Pours the diviner brightness to the cheek;
Makes the heart bound more swiftly to its bliss,
And bids the rushing blood the magnet seek—
Out from their bounds swell nerve, and pulse, and sense,
The veins in tumult would their shores o'erflow;
Body to body rapt—and charmèd thence,
Soul drawn to soul with intermingled glow.
Mighty alike to sway the flow and ebb
Of the inanimate Matter, or to move
The nerves that weave the Arachnèan web
Of Sentient Life—rules all-pervading Love!
Ev'n in the Moral World, embrace and meet
Emotions—Gladness clasps the extreme of Care;
And Sorrow, at the worst, upon the sweet
Breast of young Hope, is thaw'd from its despair.
Of sister-kin to melancholy Woe,
Voluptuous Pleasure comes, and with the birth
Of her gay children, (golden Wishes,) lo,
Night flies, and sunshine settles on the earth![15 - Literally, "the eye beams its sun-splendour," or, "beams like a sun." For the construction that the Translator has put upon the original (which is extremely obscure) in the preceding lines of the stanza, he is indebted to Mr Carlyle. The general meaning of the Poet is, that Love rules all things in the inanimate or animate creation; that, even in the moral world, opposite emotions or principles meet and embrace each other. The idea is pushed into an extravagance natural to the youth, and redeemed by the passion, of the Author. But the connecting links are so slender, nay, so frequently omitted, in the original, that a certain degree of paraphrase in many of the stanzas is absolutely necessary to supply them, and render the general sense and spirit of the poem intelligible to the English reader.]
The same great Law of Sympathy is given
To Evil as to Good, and if we swell
The dark account that life incurs with Heaven,
'Tis that our Vices are thy Wooers, Hell!
In turn those Vices are embraced by Shame
And fell Remorse, the twin Eumenides.
Danger still clings in fond embrace to Fame,
Mounts on her wing, and flies where'er she flees.
Destruction marries its dark self to Pride,
Envy to Fortune: when Desire most charms,
'Tis that her brother Death is by her side,
For him she opens those voluptuous arms.
The very Future to the Past but flies
Upon the wings of Love—as I to thee;
O, long swift Saturn, with unceasing sighs,
Hath sought his distant bride, Eternity!
When—so I heard the oracle declare—
When Saturn once shall clasp that bride sublime,
Wide-blazing worlds shall light his nuptials there—
'Tis thus Eternity shall wed with Time.
In those shall be our nuptials! ours to share
That bridenight, waken'd by no jealous sun;
Since Time, Creation, Nature, but declare
Love—in our love rejoice, Beloved One!

TO THE SPRING

Welcome, gentle Stripling,
Nature's darling, thou—
With thy basket full of blossoms,
A happy welcome now!
Aha!--and thou returnest,
Heartily we greet thee—
The loving and the fair one,
Merrily we meet thee!
Think'st thou of my Maiden
In thy heart of glee?
I love her yet the Maiden—
And the Maiden yet loves me!
For the Maiden, many a blossom
I begg'd—and not in vain;
I came again, a-begging,
And thou—thou giv'st again:
Welcome, gentle stripling,
Nature's darling thou—
With thy basket full of blossoms,
A happy welcome, now!

NATURAL HISTORY OF SALMON AND SEA-TROUT

[On the Growth of Grilse and Salmon. By Mr Andrew Young, Invershin, Sutherlandshire. (Transactions of the Royal Society of Edinburgh. Vol. XV. Part III.) Edinburgh, 1843.]

[On the Growth and Migrations of the Sea-Trout of the Solway. By Mr John Shaw, Drumlanrig. (Ibid.) Edinburgh, 1843.]

The salmon is undoubtedly the finest and most magnificent of our fresh-water fishes, or rather of those anadromous kinds which, in accordance with the succession of the seasons, seek alternately the briny sea and the "rivers of water." It is also the most important, both in a commercial and culinary point of view as well as the most highly prized by the angler as an object of exciting recreation. Notwithstanding these and other long-continued claims upon our consideration, a knowledge of its natural history and habits has developed itself so slowly, that little or nothing was precisely ascertained till very recently regarding either its early state or its eventual changes. The salmon-trout, in certain districts of almost equal value with the true salmon, was also but obscurely known to naturalists, most of whom, in truth, are too apt to satisfy themselves rather by the extension than the increase of knowledge. They hand down to posterity, in their barren technicalities, a great deal of what is neither new nor true, even in relation to subjects which lie within the sphere of ordinary observation,—to birds and beasts, which almost dwell among us, and give utterance, by articulate or intelligible sounds, to a vast variety of instinctive, and as it were explanatory emotions:—what marvel, then, that they should so often fail to inform us of what we desire to know regarding the silent, because voiceless, inhabitants of the world of waters?

But that which naturalists have been unable to accomplish, has, so far as concerns the two invaluable species just alluded to, been achieved by others with no pretension to the name; and we now propose to present our readers with a brief sketch of what we conceive to be the completed biography of salmon and sea-trout. In stating that our information has been almost entirely derived from the researches of practical men, we wish it to be understood, and shall afterwards endeavour to demonstrate, that these researches have, nevertheless, been conducted upon those inductive principles which are so often characteristic of natural acuteness of perception, when combined with candour of mind and honesty of purpose. We believe it to be the opinion of many, that statements by comparatively uneducated persons are less to be relied upon than those of men of science. It may, perhaps, be somewhat difficult to define in all cases what really constitutes a man of science. Many sensible people suppose, that if a person pursues an original truth, and obtains it—that is, if he ascertains a previously unknown or obscure fact of importance, and states his observations with intelligence—he is entitled to that character, whatever his station may be. For ourselves, we would even say that if his researches are truly valuable, he is himself all the more a man of science in proportion to the difficulties or disadvantages by which his position in life may be surrounded.

The development and early growth of salmon, from the ovum to the smolt, were first successfully investigated by Mr John Shaw of Drumlanrig, one of the Duke of Buccleuch's gamekeepers in the south of Scotland. Its subsequent progress from the smolt to the adult condition, through the transitionary state of grilse, has been more recently traced, with corresponding care, by Mr Andrew Young of Invershin, the manager of the Duke of Sutherland's fisheries in the north. Although the fact of the parr being the young of the salmon had been vaguely surmised by many, and it was generally admitted that the smaller fish were never found to occur except in streams or tributaries to which the grown salmon had, in some way, the power of access, yet all who have any acquaintance with the works of naturalists, will acknowledge that the parr was universally described as a distinct species. It is equally certain that all who have written upon the subject of smolts or salmon-fry, maintained that these grew rapidly in fresh water, and made their way to the sea in the course of a few weeks after they were hatched.

Now, Mr Shaw's discovery in relation to these matters is in a manner twofold; first—he ascertained by a lengthened series of rigorous and frequently-repeated experimental observations, that parr are the early state of salmon, being afterwards converted into smolts; secondly,—he proved that such conversion does not, under ordinary circumstances take place until the second spring ensuing that in which the hatching has occurred, by which time the young are two years old. The fact is, that during early spring there are three distinct broods of parr or young salmon in our rivers.

1st, We have those which, recently excluded from the ova, are still invisible to common eyes; or, at least, are inconspicuous or unobservable. Being weak, in consequence of their recent emergence from the egg, and of extremely small dimensions, they are unable to withstand the rapid flow of water, and so betake themselves to the gentler eddies, and frequently enter "into the small hollows produced in the shingle by the hoofs of horses which have passed the fords." In these and similar resting-places, our little natural philosophers, instinctively aware that the current of a stream is less below than above, and along the sides than in the centre, remain for several months during spring, and the earlier portion of the summer, till they gain such an increase of size and strength as enables them to spread themselves abroad over other portions of the river, especially those shallow places where the bottom is composed of fine gravel. But at this time their shy and shingle-seeking habits in a great measure screen them from the observance of the uninitiated.

2dly, We have likewise, during the spring season, parr which have just completed their first year. As these have gained little or no accession of size during the winter months, owing to the low temperature both of the air and water, and the consequent deficiency of insect food, their dimensions are scarcely greater than at the end of the preceding October: that is, they measure in length little more than three inches.—(N.B. The old belief was that they grew nine inches in about three weeks, and as suddenly sought the turmoil of the sea.) They increase, however in size as the summer advances, and are then the declared and admitted parr of anglers and other men.

3dly, Simultaneously with the two preceding broods, our rivers are inhabited during March and April by parr which have completed their second year. These measure six or seven inches in length, and in the months of April and May they assume the fine silvery aspect which characterizes their migratory condition,—in other words, they are converted into smolts, (the admitted fry of salmon,) and immediately make their way towards the sea.

Now, the fundamental error which pervaded the views of previous observers of the subject, consisted in the sudden sequence which they chose to establish between the hatching of the ova in early spring, and the speedy appearance of the acknowledged salmon-fry in their lustrous dress of blue and silver. Observing, in the first place, the hatching of the ova, and, erelong, the seaward migration of the smolts, they imagined these two facts to take place in the relation of immediate or connected succession; whereas they had no more to do with each other than an infant in the nursery has to do with his elder, though not very ancient, brother, who may be going to school. The rapidity with which the two-year-old parr are converted into smolts, and the timid habits of the new-hatched fry, which render them almost entirely invisible during the first few months of their existence,—these two circumstances combined, have no doubt induced the erroneous belief that the silvery smolts were the actual produce of the very season in which they are first observed in their migratory dress: that is, that they were only a few weeks old, instead of being upwards of two years. It is certainly singular, however, that no enquirer of the old school should have ever bethought himself of the mysterious fate of the two-year-old parr, (supposing them not to be young salmon,) none of which, of course, are visible after the smolts have taken their departure to the sea. If the two fish, it may be asked, are not identical, how does it happen that the one so constantly disappears along with the other? Yet no one alleges that he has ever seen parr as such, making a journey towards the sea "They cannot do so" says Mr Shaw, "because they have been previously converted into smolts."

Mr Shaw's investigations were carried on for a series of years, both on the fry as it existed naturally in the river, and on captive broods produced from ova deposited by adult salmon, and conveyed to ingeniously-constructed experimental ponds, in which the excluded young were afterwards nourished till they threw off the livery of the parr, and underwent their final conversion into smolts. When this latter change took place, the migratory instinct became so strong that many of them, after searching in vain to escape from their prison—the little streamlet of the pond being barred by fine wire gratings—threw themselves by a kind of parabolic somerset upon the bank and perished. But, previous to this, he had repeatedly observed and recorded the slowly progressive growth to which we have alluded. The value of the parr, then, and the propriety of a judicious application of our statutory regulations to the preservation of that small, and, as hitherto supposed, insignificant fish, will be obvious without further comment.[16 - Mr Shaw's researches include some curious physiological and other details, for an exposition of which our pages are not appropriate. But we shall here give the titles of his former papers. "An account of some Experiments and Observations on the Parr, and on the Ova of the Salmon, proving the Parr to be the Young of the Salmon."—Edinburgh New Phil. Journ. vol. xxi. p. 99. "Experiments on the Development and Growth of the Fry of the Salmon, from the Exclusion of the Ovum to the Age of Six Months."—Ibid. vol. xxiv. p. 165. "Account of Experimental Observations on the Development and Growth of Salmon Fry, from the Exclusion of the Ova to the Age of Two Years."—Transactions of the Royal Society of Edinburgh, vol. xiv. part ii. (1840.) The reader will find an abstract of these discoveries in the No. of this Magazine for April 1840.]

Having now exhibited the progress of the salmon fry from the ovum to the smolt, our next step shall be to show the connexion of the latter with the grilse. As no experimental observations regarding the future dimensions of the détenus of the ponds could be regarded as legitimate in relation to the usual increase of the species, (any more than we could judge of the growth of a young English guardsman in the prisons of Verdun,) after the period of their natural migration to the sea, and as Mr Shaw's distance from the salt water—twenty-five miles, we believe, windings included—debarred his carrying on his investigations much further with advantage, he wisely turned his attention to a different, though cognate subject, to which we shall afterwards refer. We are, however, fortunately enabled to proceed with our history of the adolescent salmon by means of another ingenious observer already named, Mr Andrew Young of Invershin.

It had always been the prevailing belief that smolts grew rapidly into grilse, and the latter into salmon. But as soon as we became assured of the gross errors of naturalists, and all other observers, regarding the progress of the fry in fresh water, and how a few weeks had been substituted for a period of a couple of years, it was natural that considerate people should suspect that equal errors might pervade the subsequent history of this important species. It appears, however, that marine influence (in whatever way it works) does indeed exercise a most extraordinary effect upon those migrants from our upland streams, and that the extremely rapid transit of a smolt to a grilse, and of the latter to an adult salmon, is strictly true. Although Mr Young's labours in this department differ from Mr Shaw's, in being rather confirmatory than original, we consider them of great value, as reducing the subject to a systematic form, and impressing it with the force and clearness of the most successful demonstration.

Mr Young's first experiments were commenced as far back as 1836, and were originally undertaken with a view to show whether the salmon of each particular river, after descending to the sea, returned again to their original spawning-beds, or whether, as some supposed, the main body, returning coastwards from their feeding grounds in more distant parts of the ocean, and advancing along our island shores, were merely thrown into, or induced to enter, estuaries and rivers by accidental circumstances; and that the numbers obtained in these latter localities thus depended mainly on wind and weather, or other physical conditions, being suitable to their upward progress at the time of their nearing the mouths of the fresher waters. To settle this point, he caught and marked all the spawned fish which he could obtain in the course of the winter months during their sojourn in the rivers. As soon as he had hauled the fish ashore, he made peculiar marks in their caudal fins by means of a pair of nipping-irons, and immediately threw then back into the water. In the course of the following fishing season great numbers were recaptured on their return from the sea, each in its own river bearing its peculiar mark. "We have also," Mr Young informs us, "another proof of the fact, that the different breeds or races of salmon continue to revisit their native streams. You are aware that the river Shin falls into the Oykel at Invershin, and that the conjoined waters of these rivers, with the Carron and other streams, form the estuary of the Oykel, which flows into the more open sea beyond, or eastwards of the bar, below the Gizzen Brigs. Now, were the salmon which enter the mouth of the estuary at the bar thrown in merely by accident or chance, we should expect to find the fish of all the various rivers which form the estuary of the same average weight; for, if it were a mere matter of chance, then a mixture of small and great would occur indifferently in each of the interior streams. But the reverse of this is the case. The salmon in the Shin will average from seventeen pounds to eighteen pounds in weight, while those of the Oykel scarcely attain an average of half that weight. I am, therefore, quite satisfied, as well by having marked spawned fish descending to the sea, and caught them ascending the same river, and bearing that river's mark, as by a long-continued general observation of the weight, size, and even something of the form, that every river has its own breed, and that breed continues, till captured and killed, to return from year to year into its native stream."

We have heard of a partial exception to this instinctive habit, which, however, essentially confirms the rule. We are informed that a Shin salmon (recognized as such by its shape and size) was, on a certain occasion, captured in the river Conon, a fine stream which flows into the upper portion of the neighbouring Frith of Cromarty. It was marked and returned to the river, and was taken next day in its native stream the Shin, having, on discovering its mistake, descended the Cromarty Frith, skirted the intermediate portion of the outer coast by Tarbet Ness, and ascended the estuary of the Oykel. The distance may be about sixty miles. On the other hand, we are informed by a Sutherland correspondent of a fact of another nature, which bears strongly upon the pertinacity with which these fine fish endeavour to regain their spawning ground. By the side of the river Helmsdale there was once a portion of an old channel forming an angular bend with the actual river. In summer, it was only partially filled by a detached or landlocked pool, but in winter, a more lively communication was renewed by the superabounding waters. This old channel was, however, not only resorted to by salmon as a piece of spawning ground during the colder season of the year, but was sought for again instinctively in summer during their upward migration, when there was no water running through it. The fish being, of course, unable to attain their object, have been seen, after various aerial boundings, to fall, in the course of their exertions, upon the dry gravel bank between the river and the pool of water, where they were picked up by the considerate natives.

No sooner had Mr Young satisfied himself that the produce of a river invariably returned to that river after descending to the sea, than he commenced his operations upon the smolts—taking up the subject where it was unavoidably left off by Mr Shaw[17 - Mr Young has, however, likewise repeated and confirmed Mr Shaw's earlier experiments regarding the slow growth of salmon fry in fresh water, and the conversion of parr into smolts. We may add, that Sir William Jardine, a distinguished Ichthyologist and experienced angler, has also corroborated Mr Shaw's observations.]. His long-continued superintendence of the Duke of Sutherland's fisheries in the north of Scotland, and his peculiar position as residing almost within a few yards of the noted river Shin, afforded advantages of which he was not slow to make assiduous use. He has now performed numerous and varied experiments, and finds that, notwithstanding the slow growth of parr in fresh water, "such is the influence of the sea as a more enlarged and salubrious sphere of life, that the very smolts which descend into it from the rivers in spring, ascend into the fresh waters in the course of the immediate summer as grilse, varying in size in proportion to the length of their stay in salt water."
