We do not clearly see, and should have been glad had the author stated, in what manner he ascertained that his St Boswell's fish had not escaped the sweeping semicircles of the lower nets some days previous. We admit that there is a great deal of Sabbath desecration committed by salmon, but we also know that they travel upwards, though in smaller number and with greater risk, during all the other days of the week; and we are curious to understand how any angler, however accomplished, can carry his skill in physiognomy to such perfection, as to be able to look a fish in the face on Monday morning, and decide that it had not left the sea till the clock struck twelve on the Saturday night preceding.

"As salmon" our author continues, "are supposed to enter a river merely for the purposes of spawning, and as that process does not take place till September, one cannot well account for their appearing in the Tweed and elsewhere so early as February and March, seeing that they lose in weight and condition during their continuance in fresh water. Some think it is to get rid of the sea-louse; but this supposition must be set aside, when it is known that this insect adheres only to a portion of the newly-run fish which are in best condition. I think it more probable that they are driven from the coasts near the river by the numerous enemies they encounter there, such as porpoises and seals, which devour them in great quantities. However this may be, they remain in the fresh water till the spawning months commence."—P. 10.

We cannot think that a great instinctive movement which seems, although with a widely extended range in respect to tine, to pervade the entire mass of salmon along our universal shores, should in any way depend upon so casual an occurrence as an onslaught by seals and porpoises, or that fear rather than love should force them to seek the "pastoral melancholy" of the upper streams and tributaries. That seals are destructive to salmon, and all other fishes which frequent our shores or enter our estuaries, is undoubted; but we have no proof beyond the general allegation, that porpoises pursue a corresponding prey. Our own researches certainly lead to an opposite conclusion. The ordinary food of the cetacea, notwithstanding their enormous bulk, is minute in size; and we have never been informed, on good authority—that is, on direct testimony—that even herrings have ever been detected in the stomach of a porpoise. Yet we have careful notes of the dissection of these creatures, taken from specimens slaughtered in the midst of millions of herrings; and these notes show that the minute food with which the sea was swarming, and which formed the sustenance for the time of the smaller fishes, also constituted the food of the cetacea, which were merely gamboling through the herring shoals.

It is certainly, however, difficult to explain the motives by which the early spring salmon are actuated in ascending rivers, seeing that they never spawn till autumn at the soonest. We must remember, at the same time, that they are fresh-water fishes, born and bred in our own translucent streams, and that they have an undoubted right to endeavour to return there when it suits their own inclination. It may be, that although the ocean forms their favourite feeding-ground, and their increase of size and continuance in high condition depend upon certain marine attributes, which, of course, they can find only in the sea, yet the healthy development of the spawn requires a long-continued residence in running waters. We have ascertained, by experiment, that the ova of salmon, after being deposited, will make no progress in still water; and we cannot illustrate this portion of the subject better than by transcribing a paragraph from a letter, addressed to us in spring, (11th April 1843,) by Mr Andrew Young of Invershin, the manager of the Duke of Sutherland's extensive salmon fisheries in the north of Scotland:—"You are aware that it has been asserted by some of our wisest doctors, that salmon spawn in the sea and in lochs, as well as in rivers. However, as doctors are proverbially allowed to differ, I have this winter been trying to test the fact in the following manner: At the same time that I deposited the spawn from which I made my other experiments, I also placed a basket of the same spawn, with equal care, in a pool of pure still water from the river Shin; and I soon found that, while that which was placed in the running pools was regularly progressing, every particle put into the still water was as visibly degenerating, so that, by the time the spawn in the running pools was alive, that in the still water was a rotten mass. I must therefore say, from the above experiment, that rivers and running streams are the places fixed by nature for salmon to hatch their young." "I would also," says our correspondent in a subsequent portion of his letter, "mention an additional experiment on another point. It has been very generally asserted that intense frost injured the spawn of salmon; and in this opinion I was myself, in some measure, a believer. But as nothing but truth will stand a proper test, I turned my attention to this subject also. During the time of our severest frost, I took a basket of spawn, and placed it in a stream, where for three days it continued a frozen mass among the ice. I then placed the basket again in the running pond from whence it had been taken, and carefully watched the effect. I found that, although exposure to extreme cold had somewhat retarded the progressive growth, it had not in the slightest degree destroyed vitality. I am therefore satisfied, that unless frost goes the length of drying up the spawning beds altogether, it does not harm the spawn, further than by retarding its growth during the actual continuance of excessive cold. Thus fry are longer of hatching in a severe winter, than during an open one with little frost."

When salmon first ascend the Tweed, they are brown upon the back, fat, and in high condition. During the prevalence of cold weather they lie in deep and easy water, but as the season advances, they draw into the great rough streams, taking up their stations where they are likely to be least observed. But there the wily wand of the practiced angler casts its gaudy lure, and "Kinmont Willie," "Michael Scott," or "The Lady of Mertoun," (three killing flies,) darting deceitfully within their view, a sudden lounge is made—sometimes scarcely visible by outward signs—as often accompanied by a watery heave, and a flash like that of an aurora borealis,—and downwards, upwards, onwards, a twenty-pounder darts away with lightning speed, while the rapid reel gives out that heart-stirring sound so musical to an angler's ear, and than which none accords so well with the hoarser murmur of the brawling stream; till at last, after many an alternate hope and fear, the glittering prize turns up his silvery unresisting broadside, in meek submission to the merciless gaff.

Many otherwise well-principled persons believe that little more is required in angling than the exercise of patience. Place a merely patient man, acquainted only with pedestrian movements, upon a strong-headed horse determined to win, and give him the start at a steeple-chase, with Lord Waterford not far behind, and it will be seen before he has crossed much country, where patience is always as useful as it is praiseworthy. Place the same patient man, if he happens to have been picked up alive, and eventually recovers, in the midst of a roaring rock-bound river, and suppose him (a thing we confess, in his case, not quite conceivable) to have hooked a twenty-pound salmon at the tail of the stream, just where it subsides into some vast, almost fathomless, and far-extended pool, and that the said salmon, being rather of a restless disposition, and moreover somewhat disquieted by feeling an unaccustomed barb in his cheek or tongue, takes his 300 yards down the deep water at a single run, and then goes helter-skelter over a cataract, which had occupied him most of the preceding Sunday to ascend, after many a sinewy but unsuccessful spring! Will patience avail a man any thing in such a predicament, when he ought rather to run like an Arab, or dive like a dolphin, "splash, splash, towards the sea," notwithstanding the chance of his breaking his neck among the rocks, or being drowned while trying to round a crag which he cannot clamber over? Let us hear Mr Scrope's account of his third cast, one fine morning, when he came to Kingswell Lees.

"Now every one knows that Kingswell Lees, in fishermen's phrase, fishes off land; so there I stood on terra dura, amongst the rocks that dip down to the water's edge. Having executed one or two throws, there comes me a voracious fish, and makes a startling dash at 'Meg with the muckle mouth.'[[10]] Sharply did I strike the caitiff; whereat he rolled round disdainful, making a whirl in the water of prodigious circumference; it was not exactly Charybdis, or the Maelstrom, but rather more like the wave occasioned by the sudden turning of a man-of-war's boat. Being hooked, and having by this time set his nose peremptorily down the stream, he flashed and whizzed away like a rocket. My situation partook of the nature of a surprise. Being on a rocky shore, and having had a bad start, I lost ground at first considerably; but the reel sang out joyously, and yielded a liberal length of line, that saved me from the disgrace of being broke. I got on the best pace I was able, and was on good ground just as my line was nearly all run out. As the powerful animal darted through Meg's Hole, I was just able to step back and wind up a few yards of line; but he still went at a killing pace, and when he came near to Melrose bridge, he evinced a distressing preference for passing through the further arch, in which case my line would have been cut by the pier. My heart sunk with apprehension, for he was near the opposite bank. Purdie, seeing this, with great presence of mind, took up some stones from the channel, and through them one by one between the fish and the said opposite bank. This naturally brought Master Salmo somewhat nearer, but still, for a few moments, we had a doubtful struggle for it. At length, by lowering the head of the rod, and thus not having so much of the ponderous weight of the fish to encounter, I towed him a little sideways; and so, advancing towards me with propitious fin, he shot through the arch nearest me.

"Deeply immersed, I dashed after him as best I might; and arriving on the other side of the bridge, I floundered out upon dry land, and continued the chase. The salmon, 'right orgillous and presumptive,' still kept the strength of the stream, and abating nothing of its vigour, went swiftly down the whirls; then through the Boat shiel, and over the shallows, till he came to the throat of the Elm Wheel, down which he darted amain. Owing to the bad ground, the pace here became exceedingly distressing. I contrived to keep company with my fish, still doubtful of the result, till I came to the bottom of the long cast in question, when he still showed fight, and sought the shallow below. Unhappily the alders prevented my following by land, and I was compelled to take water again, which slackened my speed. But the stream soon expanding, and the current diminishing, my fish likewise travelled more slowly; so I gave a few sobs and recovered my wind a little, gathered up my line, and tried to bring him to terms. But he derided my efforts, and dashed off for another burst, triumphant. Not far below lay the rapids of the Slaughterford: he would soon gain them at the pace he was going: that was certain—see, he is there already! But I back out again upon dry land, nothing loth, and have a fair race with him. Sore work it is. I am a pretty fair runner, as has often been testified; but his velocity is surprising. On, on, still he goes, ploughing up the water like a steamer. 'Away with you, Charlie! quick, quick, man—quick for your life! Loosen the boat at the Cauld Pool, where we shall soon be,' and so indeed we were, when I jumped into the said craft, still having good hold of my fish.

"The Tweed is here broad and deep, and the salmon at length had become somewhat exhausted; he still kept in the strength of the stream, however, with his nose seawards, and hung, heavily. At last he comes near the surface of the water. See how he shakes his tail and digs downwards, seeking the deep profound that he will never gain. His motions become more short and feeble: he is evidently doomed, and his race wellnigh finished. Drawn into the bare water, and not approving of the extended cleek, he makes another swift rush, and repeats this effort each time that he is towed to the shallows. At length he is cleeked in earnest, and hauled to shore; he proves one of the grey-skull newly run, and weighs somewhat above twenty pounds. The hook is not in his mouth, but in the outside of it: in which case a fish being able to respire freely, always shows extraordinary vigour, and generally sets his head down the stream.

"During the whole period of my experience in fishing, though I have had some sharp encounters, yet I never knew any sport equal to this. I am out of breath even now, whenever I think of it. I will trouble any surveyor to measure the distance from the Kingswell Lees, the starting spot, above Melrose bridge, to the end of the Cauld Pool, the death place, by Melrose church, and tell me how much less it is than a mile and three quarters,—I say, I will trouble him to do so; and let him be a lover of the angle, that he may rather increase than diminish the distance, as in good feeling and respect for the craft it behoves him to do."—P. 174.
