THE PLANT WORLD 139 



and single-hearted efforts now being made for plant preservation by 

 Rhodora and Boston botanists generally, there is no doubt that we were 

 in the wrong, and we wish to withdraw absolutely any personal imputa- 

 tions tliat we may have unwittingly made. While our opinion as to the 

 expediency' of inserting such an advertisement in the pages of a botan- 

 ical journal remains unchanged, we now know that in their motives the 

 editors and owners of Rhodora were thoroughly sincere, and entirely 

 guiltless of any thought of sacrificing plant life for pecuniary consid- 

 erations. 



The reasons for admitting the advertisement have already been set 

 forth in Rhodora, and it has been demonstrated, we think, beyond ques- 

 tion that the localities enumerated are not sufficiently exact to endanger 

 the plants, or if exact stations are given they are for such species as 

 exist in the Aroostook region in countless abundance. And another 

 claim made by the journal is that by means of this advertisement summer 

 travel may ultimately be more or less deflected from such places as Mount 

 Washington, where the alpine flora is really in danger of extinction. 

 On the other hand, as we have observed, from the standpoint of expe- 

 diency alone we consider the admission of the advertisement unwise, 

 because of the effect it may have on persons elsewhere, who may chance 

 to read of the abundance of a certain species in Maine and may think 

 it no harm to pluck the plant freely in Vermont or New Hampshire, 

 where it may be rare. But this is a matter largely of individual opin- 

 ion, and we are rejoiced that in respect to the main issue we can join 

 hands heartily with our New England friends and with the Society 

 for the Protection of Native Plants, for which we wish all possible 

 success.

In this book are described and illustrated the insect galls occurring 

 in the British Isles, so far as the author has at present been able to get 

 them determined with the exception of those occurring on oak, which are 

 so numerous that they have been reserved for separate treatment. The 

 galls are arranged in four groups, as follows : Koot-galls, stem-galls, leaf- 

 galls and flower-galls. In the discussion of each gall the name of the 

 organism causing the gall is given and botanical name of the host.
