Journal of the Royal Horticultural Society, vol. XXXV. 



Abs. Nature, No. 2131, Vol. 84, Sept. ist, 1910, p. 271. 



The two "Master's lectures" on the adaptation of the plant to the 

 soil, delivered by Mr. A. D. Hall before the Fellows of the Royal 

 Horticultural Society, are published in the Journal of the Society 

 (vol. XXXV, part i). Perhaps the most instructive lessons are based 

 on the reading of crop-distribution maps, from which the author 

 deduces the primary importance of the mechanical composition of 

 the soil. 



Following these articles, the Journal contains, amongst the con- 

 tributions, a paper by Mr. C. C. Hurst on the application of Men- 

 del's laws of heredity to horticulture, an account by Miss E. Ar- 

 mitage of cultivation by the peasants in Madeira, and notes on 

 insect pests in the West Indies by Mr. R. Newstead. 



Mr. Hurst quotes from recent experiments by Cambridge workers 

 iu connection with the elucidation of the complicated colours of 

 the snapdragon and variation in sweet peas, and discusses the origin 

 of " albino " orchids, which can be explained upon the assumption 

 of two complementary colour factors.
