Increase the grape yield by spraying for insects and diseases, A. L. Quain- 

 TANCK and C. L. Shkar {Nehr. Uort., 7 {1911), No. 4, pp. .}-6).— This paper con- 

 tains directions for the control of the more important insect and fungus pests

 ment with coconut trees started by the Seychelles Botanic Station in 1916 is

 scribed.

The forests of Jftaryland, F. W. Besley (Baltimore: Md. State Bd. Forestry, 

 1916, pp. 152. pis. ^0). — The results are given of a forest survey of the counties

 character and extent of the forest areas and the approximate stand of timber. 



Introductory considerations deal with the present forest conditions in the 

 State as a whole, their value to the people, and how they may best be con- 

 served, native forest trees, principal and special uses of the forests, wood-using 

 industries, transportation, markets, forest planting. State forest reserves, 

 municipal forests, etc. A summary of the production of lumber, timber, and 

 by-products in 1914, together with the forest laws of Maryland, is also included. 



Forestry investigations (Minnesota Sta., Rpt. Grand Rapids Substa., 1916, 

 pp. 51-60, figs. 3). — The present condition of the forest plantation is noted and 

 data are given showing the growth of Norway, white, Scotch, and jack pines 

 planted in 1900 and 1901 at varying distances, alone, and in combination. 



Forest progress in the Drakensberg, J. S. Henkel (So. African Jour. Set.,
