“He must now take one or two large marks, that he will be sure to know again, as close to the birds as possible; and also another, about two or three hundred yards immediately above, further inland. Having done this, let him take a very wide circle and come round upon his inland mark. He must now walk as if treading upon glass; the least rustle of a bough, or crack of a piece of rotten wood under his feet, may spoil all, especially if the weather be calm. Having got to about one hundred yards from where he supposes the birds to be, he will tell his retriever to lie down; the dog, if well trained, will at once do so, and never move. His master will then crawl forward, until he gets the advantage of a bush or tuft of reeds, and then raise his head by inches to look through it for his other marks. Having seen them, he has got an idea where the birds are, and will, with the utmost caution, endeavour to catch sight of them. I will suppose him fortunate enough to do so, and that they are perfectly unconscious of his near approach. He must lower his head in the same cautious manner, and look for some refuge at a fair distance from the birds, through which he may fire the deadly sitting shot. After creeping serpent-like to this, he will again raise his head by hair-breadths, and, peeping through the bush or tuft, select the greatest number of birds in line; then drawing back a little, in order that his gun may be just clear of the bush for the second barrel, after having fired the first through it, will take sure aim at his selected victims. Should he unfortunately not find an opening to fire through, the only other alternative is by almost imperceptible degrees to raise his gun to the right of the bush, and close to it; but in doing this the birds are much more likely to see him, and take wing. Never fire _over_ the bush, as you are almost certain to be perceived whenever you raise your head: more good shots are lost to an experienced hand by a rapid jerk, not keeping a sufficient watch for stragglers, and over-anxiety to fire, than in any other way. Having succeeded in getting the sitting shot, the fowl, especially if they have not seen from whence it comes, will rise perpendicularly in the air, and you are not unlikely to have a chance of knocking down a couple more with your second barrel; but if they rise wide, you must select the finest old mallard among them, or whatever suits your fancy. Directly upon hearing the report, your retriever will run to your assistance, and, having secured your cripples, you will reload, and, taking out your glass, reconnoitre again; for though ducks, widgeon, &c., should fly out upon the loch at the report of your gun, yet the diver tribe, if there are only one or two together, are perhaps more likely to be under water than above when you fire: but more of them by and by.
