M. GASTON ALLARD OF ANGERS. 181 



Ecole d'Agriculture de Grand Jouan where he learned his 

 botany, which led him some years later to establish his 

 Arboretum de la Maulevrie. 



He travelled extensively for three years in Algeria, Tunis, 

 and Morocco, when he made the flora of those countries his 

 especial study at a time when travel there was a matter of 

 much difficulty and some danger. 



He settled at Angers in 1862, and a few years later began to 

 form his Arboretum, which to-day contains a full collection of 

 trees from North America, China, Japan, and the Mediterranean 

 littoral. 



He has bequeathed this collection of half a century to the 

 Pasteur Institute, and it is expected that his house will be 

 used by the Institute as a laboratory of vegetable biology. 

 Doubtless he felt that this was a more certain way to preserve 

 it to posterity than to leave it to the Angers Municipality, which 

 is an elective body. 



M. Allard's garden, though well known to British tree lovers, 

 is not, I think, so well known in France. Few of his fellow- 

 townsmen were aware of the great fame of his collection. 

 Let us hope that its new owners will bestow the same skill 

 and thought upon its care and enrichment as M. Allard 

 himself would have wished for it. 



17. Damage to Vegetation by Smoke and Fumes. 



By Alexander Lauder, D.Sc, 

 Hon. Consulting Chemist to the Society. 



The comprehensive report of the " Selby Smelter Commission " 

 (published by the U.S. Dept. of the Interior, Bureau of Mines, 

 Bulletin 98, 1915) is the most important contribution to this 

 subject which has been made in recent years. 



The report is well worthy of serious study, not merely on 

 account of the exhaustive nature of the enquiries carried out 

 and the value of the results obtained, but because of the great 

 advance which has been made by the appointment of this 

 Commission in the method of settling disputes involving scientific 

 evidence and investigation. 



The early history of the dispute which led to the appointment
