them to, whereby indeed botany came into 

 fashion. Of botany there are always these 

 two schools the pharmacist's and the gar- 

 dener's; so its professors belong essentially 

 to one or other, sometimes partly to both, but 

 never thoroughly : that is too much to ask. 

 The zoologists then ? These are hunters; 

 first out after big game with its dangers, its 

 trophies; after birds too, and their plumage. 

 Sometimes there comes to one the vision of 

 St. Hubert, and then he lays aside his gun, and 

 takes up his notebook or his camera, Darwin

 of the hunter type in fact, a born truant, 

 the stuff true poachers are made of. 



Other naturalist-hunters come down to 

 smaller and smaller deer, next to their fleas 

 and midges, and now to-day are hunting out 

 the parasites within these, and to some pur- 

 pose. Other naturalists, again, are fishermen, 

 increasingly expert, their huts and pools grow-

 the sea from its surface-plankton to abyssal 

 dredgings ; and these from Arctic to Antarctic. 

 Plainly then, the natural sciences grow up along 

 with practical life and ever learn from it anew.
