ANNUAL REPORT OF THE SECRETARY OF 

 AGRICULTURE FOR 1900. 



Secretary Wilson begins his report 

 with a complimentary reference to the work 

 of his predecessors which has brought the 

 Department of Agriculture to its present 

 state of efficiency. He declares his own 

 aims to bring the Department scientists to 

 the help of the producers, to ascertain what 

 we import that they can produce, with a 

 view to encouraging its growth ; to search 

 the world for grains, fruits, grasses and 

 legumes, that they may be domesticated 

 here and be an improvement on what we 

 have ; to secure new and improved varieties 

 of plants by cross-fertilization ; to cooperate 

 with the experiment stations in all the 

 States and Territories in research of practi- 

 cal value to the people of all sections ; and 

 to seek out new markets for our surplus 

 products. 



Mr. Wilson emphasizes the manner in 

 which this Department differs from others. 

 He says its appropriations should be re- 

 garded as an investment, for the reason 

 that it makes direct returns therefor by 

 adding to the wealth of the country, thus 

 adding yearly largely to the profits of the 

 farmers and others as the result of its in- 

 vestigations. He instances as money-sav- 

 ing or money-making agencies the Weather 

 Bureau ; the meat inspection ; the patho- 

 logicalinvestigations of plants ; the services 

 of the entomologist ; the services of the
