are passed over by the ordinary collector; so that it is still probable for the present enumeration to be extended. If instructions were given for these small birds to be sent home in spirit much more would be known about them; for the tired waggon-traveller to keep awake and skin these small creatures is a thing to be hoped for rather than expected. In all orders, the smaller the species the more difficult to acquire—at least, in South Africa, where many a good sportsman, both Boer and Briton, will cheerfully take the trouble to procure you an animal of size, but will resent being asked to collect and skin Warblers.
We have heard of pianos accompanying our military columns to help while away the monotonous expeditions over a lonely veld. We would propose that this series of faunistic books should be supplied to every mess-room, whether peripatetic or otherwise.
