A rule which can be safely applied, to all tropical climates is that the dry season is best for either collecting, sport, or travel. Never collect in the rainy season if you can help it. Animal life is doubly hard to find, specimens are desperately difficult to preserve, and field work is very trying on the patience and the constitution.
In the Arctic regions, hunting and collecting must be done in midsummer, or not at all. While it is true that in the torrid and temperate zones there is a certain amount of work to be done all the year round, there is always a particular season which may be regarded as the harvest-time.
Collecting by Amateurs.—There is one kind of collecting which should be discouraged in every possible way, and that is the postage-stamp style of collecting by boys who have no real love for natural history. Boys in their teens often make collections of bird-skins, eggs, and nests in precisely the same spirit that prompts them to gather coins, postage stamps, and autographs—"to see who can get the most kinds." This vicious propensity is apt to involve a very good boy in a useless and inexcusable warfare against the feathered tribes. Many a time I have been saddened by the sight of drawer upon drawer, full to overflowing, of poorly made skins of our most beautiful songbirds,—hundreds of them in a single collection, perhaps not worth ten cents apiece in any market,—each skin merely recording the important fact that it was shot on a certain day in a certain place. There is a way to prove whether a juvenile collector has really a love for the study of birds. Let the one who furnishes the sinews of war—parent, guardian, or elder brother—demand that he shall mount every good specimen he kills, and be able to tell all about its habits, food, economic value, etc. This will in any event result in great good. If the collector is not really absorbed in the study of bird-life, the labor such a course involves will soon deter him from indiscriminate slaughter; and even if he is destined to become a distinguished member of the A.O.U., it will be all the better for him to be taught to place a high value on every bird, living or dead.
Shooting Birds as a Pastime.—I cannot, without being profane, find language strong enough to adequately express my abhorrence of the damnable practice some parents have of providing thoughtless boys with shot-guns and ammunition for the slaughter of birds and small mammals, just for the fun (!) of the thing, or to become proficient in the use of the gun. For the killing of birds for food, or to mount for the cabinet, or to study intelligently, there is some excuse; but for the slaughter of birds as a boyish pastime there is no excuse whatever, and either boys or parents who have such a disregard for life as to make it possible should be fined as heavily as can be done under the law. Firearms and their users are multiplying at such a frightful rate that it seems highly probable the time will come when there will be no more wild birds or quadrupeds left upon the face of the earth.
It is a good thing for a boy to be taught to shoot, and skill in the use of a rifle may fairly be regarded as an accomplishment; but the taking of life is not in the least necessary to its acquirement. If a boy wants to shoot for the sake of becoming an expert with the gun, give him a rifle and a target, or a shot-gun and clay pigeons, that he may start in the right direction. Do this, and the chances are ten to one that he gets ten times the sport and twenty times the benefit out of rivalry at the target that he would out of roaming over the country and killing every bird he can discover. Even in the immediate vicinity of Washington a song-bird can hardly raise a note without attracting a boy with a gun.
Poisoning and Trapping Mammals.—Inasmuch as there are in print a number of good books that treat this subject exclusively, I may be spared the labor of taking it up here. The reader must be assured, however, that traps and strychnine are very valuable allies in collecting, and he who ignores them will lose much. Above all things, carry with you plenty of strychnine, use it industriously, and it will bring you many a fine carnivore you would not get otherwise. Poison a skinned carcass by cutting gashes an inch deep in the rump and other fleshy portions, and putting strychnine in them. Also cut up chunks of meat in little cubes, put poison in the centre of each, and scatter them around for the benefit of the wily wolf and fox, the fat and festive badger, the wary golden eagle and raven, and other meat-eaters in general. On our hunt for buffaloes in Montana, Mr. W. Harvey Brown was our Borgia, and his industry and strychnine laid low some of the finest small specimens we obtained, including specimens of all the species mentioned above. After putting out poison, search the vicinity thoroughly for two or three days, and the chances are your efforts will not be in vain.
Dr. C. Hart Merriam and his collectors have reduced the trapping of the very small mammalia to an exact science, the like of which I venture to say has never been seen before. They use three kinds of traps—the Lamb steel-trap, No. 0; the Cyclone, and the Climax. These are all small, all may be used with bait, or quickly modified to serve as runway traps, for arvicolas and the like. Boiled oatmeal mixed with corn meal is the standard bait used for small rodents. For shrews, small carnivora, and omnivorous rodents, meat baits are used, such as birds' heads, intestines, pieces of skin, and meat—in fact anything fleshy.
