These astronomical facts had a bearing on our entomological operations, since we had to grow accus-tomed to the fact that the most promising hunting-grounds were slopes with a north-cast aspect. Faithful to our own science rather than to the associa-tion of which we were members, we had decided to go on to Durban by the same steamer, and put in as many days collecting as possible on the Natal Coast. This left us but a day and a half at Cape Town, in which to get a glimpse of its fauna and flora, and we were truly fortunate in that the Southern spring smiled upon us and provided, if indeed few insects, at any rate what Mr. Boswell would have termed "some fine prospects."
