XCVT REPORT OF THE SECRETARY OF AGRICULTURE. 



(2) That reservoirs located in the channels of running streams should 

 be public works. 



(3) That the first step toward national aid for irrigation should be 

 the passage of enlightened codes of water laws by the States to be 

 benefited. 



(1) That the land laws should be modified by repealing the Desert 

 Act and by requiring cultivation as well as residence on a homestead. 



(5) That the nonirrigable grazing lands should be leased in small 

 tracts so as to unite the irrigable and the pasture lands. 



DIVISION OF ENTOMOLOGY. 



The principal work accomplished by the Division of Entomology 

 during the fiscal year ended June 30, 1901, is as follows: 



ESTABLISHMENT OF SMYRNA FIG GROWING. 



The practical completion of the investigations which resulted in 

 the introduction and establishment in California of the fig-fertilizing 

 insect {Blastophaga grossorum). An assistant was sent to Fresno in 

 1900, remaining there throughout the season, making observations 

 which completed the life history of the insect and resulted in the 

 ascertaining of important facts previously unknown, although in south- 

 ern Europe the insect had been known and studied for very many 

 years. He also took active part in the practical work of handling the 

 insect and fertilizing the crop. Eleven tons of Smyrna figs were 

 raised, dried, and placed on the market, and tests made by chemists 

 and fruit experts show these figs to be superior to the imported prod- 

 uct. The insects were successfully carried through the winter of 

 1900-1901, many of them hibernating successfully without cover; and, 

 although not coming under the head of the fiscal year in question, it 

 may be interesting to add that in the autumn of 1901 the crop of 

 Smyrna figs was so abundant as to be difficult to estimate. Certainly 

 more than 50 tons were gathered, and the full crop may possibly have 

 reached as high as 75 tons. The fertilizing insect has been thoroughly 

 established at several other points than Fresno, and the Division of 

 Entomology now holds itself in readiness to see that a supply of the 

 fig insects is furnished to any fig grower after he has succeeded in 

 raising to the bearing stage caprifig trees and Smyrna fig trees. 



WORK AGAINST THE SAN JOSE SCALE. 



Several predatory insects have been imported from different for- 

 eign countries. and good results to American agriculture are expected. 

 The most important of these will doubtless prove to be an enemy of 

 the San Jose scale, which has been brought over from China.
