ORGANIZATION OF COLLABORATIVE WORK. 



In continuation of the cooperative experimental work with su^ar 

 beets carried <>n in IIMMI" l>y this liureau in collaboration with certain 

 experiment stations and the Weather Bureau, the following letters 

 were addressed to the experiment stations of North Carolina, Iowa, 



Michigan. I'tali. Indiana, Wisconsin. Kentucky, and to the two New 

 York stations in the spring of 1901:

IM.KK SIR: For the collaborat ive work in the study of the influence of environ- 

 ment on the composition of the sugar beet for the present year, I have decided to 

 use seed No. 5772, Dippe's Kleinwan/lebener Klite, and 20 pounds of this seed 

 marked "special" have been sent to you for such collaborative work. 



The area planted need not exceed an eighth of an acre, unless you desire a larger 

 area or a number of plots. This matter is left entirely to your own judgment, and 

 the residue of the seed you can dispose of as you like. I suggest, however, that the 

 special plot be seeded very heavily, so as to be sure of a good stand, and that enough 

 of the seed be reserved for replanting in case the first planting should not germinate. 



I will send you in a few days a blank giving some special points in regard to tin- 

 study of the environment which I should be glad to have you observe during 

 the season.

DEAR Siu: In connection with the collaborative study of the influence of environ- 

 ment on the composition of the sugar beet, I desire to make a careful chemical and 

 physical analysis of the soils of the plots used for the growing "f the heet>. 



I therefore ask that you take a representative sample of the soil and subsoil of the 

 plot on which you grow the No. 5772 "special" seed during the present year. After 

 getting such a sample, reduce it in si/e by quartering or otherwise, so as to secure a 

 representative subsample weighing about 1 pounds, and scud under the inclosed 

 frank by mail to my address. 



II. \V. \VII.KY. Cfamfct, 



On March 20, 1901, the seed was mailed to the stations named by 

 the Section of Seed and Plant Introduction, and on March L':I the 

 following letter was addressed to the cooperating stations:

DEAR SIR: In order that I may be put into direct communication with the otlicial 

 of your station who will be in personal charge of the collaborative work mi the study
