The trout in our streams rarely exceed a pound in weight: this may, in some degree, be accounted for from the circumstance, that the Devon and Cornish rivers are very rapid, consequently, the insects which fall from the bushes, are carried so swiftly down the stream, that whilst a fish is engaged in seizing on one, the others pass rapidly by: the same remarks may, in times of flood, apply to worms, &c. In more tranquil rivers a fly seldom escapes; it lights, or is blown on the water, is immediately espied, and the fish, whilst occupied in seizing one, has half-a-dozen in his eye, each awaiting his leisure in calm repose. That our trout will increase rapidly, under favorable circumstances, I can testify from my own experience. I knew several that were placed in a pond, in August, which averaged from eight to ten ounces; in the July following, I caught the same fish with a fly, which averaged from one pound to one pound and a half.

Before taking leave of trout, I must notice a fly which may be used with success after sunset, in the months of July and August. It is called the white moth, and has often given me sport as late as ten and eleven on fine moon-light nights. Choose an open place on a tranquil portion of the river; the fly may be thrown with less nicety than in the day-time, and catching a fish does not alarm the neighbouring fry, who will frequently seize the moth immediately after the water has been disturbed by the efforts of the captured fish to rid itself from the hook.

Fly-fishing for salmon is seldom pursued in these counties. The fish meets with such a host of formidable enemies as soon as it quits the sea, that comparatively few ascend our rivers. The intent of the proprietors of our fisheries appears to be the annihilation of this prince of fishes. The most impracticable weirs are constructed, over which it is almost impossible for a fish to leap; in the pools immediately below, the rapacious fisherman casts his net every tide; whilst above, if perchance a fish does succeed in evading the cunning of his netting foes, a host of spearmen are on watch by night, as well as by day, to immolate the persecuted wanderer.

Laws exist, restricting the capture of salmon, within certain months; but that which in this case is truly everybody’s business, is considered nobody’s; consequently, in season and out of season are they caught, sold, and devoured, as openly as if no penalties were incurred by the act. That food, which under proper regulation would soon become abundant and reasonable, can only now be placed on the tables of the affluent.

The preservation of salmon I hold to be a question of national importance; so much so, that I consider conservators should be appointed to protect them, as well from the unlawful proceedings of the owners of fisheries, as from the unscrupulous acts of the poacher. Weirs should be so constructed as to admit of their ascending whenever the waters are swollen by floods; hutches should be kept open at least forty-eight hours during the week.

Besides the perils which await the parents on their journey from the sea, their young are also in imminent danger on their route towards the sea. The millers take them in traps, by thousands, and dispose of them by the gallon to the neighbours; indeed, at times they are taken in such vast quantities that pigs are regaled upon their delicate flesh.

Man is not content with employing his own ingenuity in capturing this delicious fish, he calls to his aid the sagacity of the dog, which we find becomes, by practice, as expert a fisherman as his master: numerous instances of this are on record. The following are well-established facts:—In the work by the Reverend William Hamilton, an interesting account is related of the assistance afforded by a water-dog to some salmon fishermen, when working nets in shallow pools. The dog takes his post in a ford where the water is not very deep, and at a distance below the net; if a salmon escapes the net, the fish makes a shoot down the river, in the direction towards the sea; the dog watches, and marks his approach by the ripple on the water, and endeavours to turn the fish back towards the net, or catch him; if he fails in both attempts, the dog then quits the water, in which the pace of the fish is too fast for him, and runs with all his speed down the bank to intercept the fish at the next shallow ford, where another opportunity, and a second diverting attempt, occurs.

Dogs are occasionally used in Glamorganshire, when trying for salmon. They appear to take great pleasure in the pursuit, exhibiting by turns the most patient watchfulness, persevering exertion, or extraordinary sagacity, as either quality may best effect the wishes of the master.

In some parts of Wales, where the rivers are narrow, the salmon are caught in a net drawn by men on each bank; dogs are trained to swim over from side to side, with the head and ground lines of the net, as required.

A clever poacher at Totnes, allows that he has killed many salmon in the night, on the Dart, by setting a trammel net at the lower end of the deep pools, by sending in a dog at the upper end of the pool, which dog he had trained to dive like an otter. The fish, as soon as the dog dived, immediately dashed down the stream, and were taken in the net at the lower end of the pool.
