The above solutions were applied in 2 per cent, strength with the 

 exception of the sulphate of iron (1 per cent.), and the milk of lime 

 (4 per cent.). It can be seen that five of these spraying materials 

 increased to a greater or less extetit the yield of the potatos and 

 two produced a decrease, but that all of them caused some decrease 

 in the percentage of starch as compared with the unsprayed plot.

Afforestation in Scotland. By Lord Lovat and Captain Stir- 

 ling, of Kier. — This is one of the most up-to-date and valuable papers 

 on the vexed question of afforestation that has come under our notice. 

 Nothing of importance seems to have been omitted, and each subject 

 has been' carefully prepared by those who have had a practical know- 

 ledge of the formation and general management of woods and planta- 

 tions.— i. D. W. 



Ag-ricultural Education, American. A. C. True and D. J. 



Crosby {U.S.A. Dep. Agr., Office of Expt. Stn., Circ. 106, p. 28; 

 Feb. 1911 ; 8 plates). — The circular gives an account of the efforts 

 made to supply technical agricultural education in America. Courses, 

 of varying lengths, are planned to meet all requirements. One may 

 take a complete course, ending in a degree ; or a short evening or winter 

 course, enabling one to understand more clearly the reasons for the 

 daily farm operations. 



Special courses are arranged for teachers, extending over twelve 

 months or two years. 



For those distant from the teaching centres extension lectures and 

 correspondence courses are arranged. 



The extension lecturers are specially trained men, who can put the 

 facts of the case tactfully and succinctly before their hearers.
