EXPERIMENT STATION RECORD. 



This cooperative experinieut was almost flni)licate<l by another at Waipahu, 

 where the elevation is approximately the same but the rainfall estimated to be 

 about 35 in. per annum. Here Mit Afifi and Seabrook produced the highest 

 yields of lint, 101^ and 87^ lbs. per acre, respectively. Early plantings inva- 

 riably excelled late plantings in yield. 



t At the station 30 standard cotton varieties have been planted. In a test of 

 1,200 buds inserted 31 per cent have made satisfactory growth, and from 10 to 

 60 per cent of the cuttings made took root. In minor trials under more 

 favorable conditions the percentage of successful cuttings exceeded 80. 



Eighth biennial report of the state engineer to the governor of Idaho, 

 1909-10, D. G. Martin (Bicn. Rpt. State Enyin. Idaho, 8 {liW9-10), pp. 367, 

 figs. If ) . — This is a report of work done under a cooperative agreement between 

 the state board of land engineers and the Irrigation Investigations of this Office. 



The author states in detail the soil and other conditions under which the 

 work was done. " Throughout the investigation the amount of water producing 

 the greatest yield is considered as the one most nearly approaching the proper 

 amount for the soil and crop in question." The following table states the 

 principal results obtained :

Report of general work on the Buncombe and Transylvania test farms, 

 R. W. CoLLETT (Bill. N. C. Dcpt. Agr., I91I, Feb., Sui). pp. J,-1G, figs. II).— The 

 Buncombe and Transylvania test farms are described and their work briefly 

 outlined. 



At the Buncombe farm the work with fertilizers " has shown, as a rule, that 

 the soils on this farm do not respond profitably to applications of nitrogen or 

 potash, but respond readily to applications of phosphoric acid. . . . Two extra 

 cultivations gave 10 bu. increase of corn per acre." Three years experimental
