THE ^HAWAIIAN 



rOREST£R I AGRICULTURIST 



Vol. IV. MARCH, 1907 No. 3 



The work of Dr. N. A. Cobb at the H. S. P. A. Experiment 

 Station is Hkely to prove of great value to the agricultural in- 

 dustries of Hawaii, and the Territory is extremely fortunate in 

 having the opportunity to benefit by the knowledge of such an 

 authority on plant pathology. Dr. Cobb will remain in the 

 islands until June 30, during which time he will be actively 

 engaged in determining the plant diseases which have become 

 established here. At the expiration of this period he will 

 proceed to Washington, and will take with him such material 

 as he has not opportunity to work up in Honolulu. An ex- 

 cellent occasion is now afiforded to get plant diseases examined 

 and reported upon, whether obscure and little known ones or 

 those of more general prevalence. To this purpose Dr. Cobb 

 has issued an invitation to all interested in the subject to for- 

 ward to him specimens for examination. The importance to 

 agriculture of a wide response to the circular, which appears in 

 this issue, is very great, as the data gathered by this means 

 will afford knowledge not only of the presence of various plant 

 diseases, but will help to determine the range of their distri- 

 bution and will form a basis for determining the best means 

 to successfully combat them. 



Upon his arrival at Washington, Dr. Cobb will assume 

 control of the new office of Crop Technology, of the Bureau 

 of Plant Industry, United States Department of Agriculture. 



This number contains the first of a series of special articles 

 on entomology, to be complete in four or five issues, by Mr. 

 Jacob Kotinsky, of the Division of Entomology, Board of Ag- 

 riculture and Forestry. Mr, Kotinsky has long been a regular 

 contributor to our pages upon entomological subjects, but the 

 articles now commencing are upon special matters, and the 

 series will be complete in itself. 



We have recently received from Mr. Jared G. Smith, a 

 most interesting paper upon Cassava cultivation. Pia is a 

 well-known Hawaiian food, and the product of cassava is also 

 one of the chief comestibles of the inhabitants of the West 

 Indies. Mr. Smith's article will appear in the next number.
