In the matter of collecting apparatus, the newer powders are preferable, as with them there is less chance, through absence of smoke, of losing sight of the specimen as it falls, which is often the case otherwise. It is well to have cartridge cases of different colours for ease in selection, and the sizes of shot most useful seem to be:--SSG for pigs, deer, and large monkeys; AA and II for monkeys, eagles, and other large birds; V for pigeons, and others of similar size in high tree tops; VIII for the same at moderate range, and for smaller birds and squirrels, etc., when distant; while 2 drams of powder and 1/2 ounce of XI shot--the cartridge filled out by several wads between the two--is most useful for small birds and animals up to 20 yards, and for others at proportionate distances. For such little things as sunbirds, and for snakes, lizards, or for point-blank shots, we carried auxiliary barrels, about 9 inches long, that can be slipped in and out of the gun like an ordinary cartridge, and which fired an extra long .32 calibre brass cartridge loaded with a pinch of dust shot (No. XIII). These were invaluable for obtaining the smaller specimens without smashing, and had a killing range of about 12 yards.
There is no more perfect weapon for the collecting naturalist than the three-barrelled guns that we used--shot barrels fully choked, and the third, placed beneath the others, rifled for long .380 cartridges. With one of these, the auxiliary barrel, and a proper selection of cartridges, one is ready for anything that may turn up other than the larger "big game," for the equipment is so portable that there is no temptation ever to leave part of it behind.
The only drawback to such an outfit lies in the time lost in selecting a suitable cartridge for each shot, but the perfect specimens obtained by this method are ample compensation for the extra trouble involved. Even in this way accidents sometimes happen however, as when on one occasion, while walking through some grass, a tiny button-quail sprang up, and was knocked over at close range with what was thought to be a small charge of No. XI shot. The specimen was not found at once, but as it was the first of the kind obtained (and has since proved to be of a new species), the search was persisted in until after a quarter of an hour a little purple pulp attached to a wing was discovered. The collector had forgotten which barrel contained the smaller cartridge, and, pulling the wrong trigger, had fired a full charge of No. VIII from about that distance in yards, at a wretched little bird about the size of a sparrow!
