46. Annual loss due to insect pests of 

 the United States.' — " In no comitry in 

 the world do insects impose a heavier tax on 

 farm products than in the United States. 

 The losses resulting from the depredations 

 of insects on all the plant products of the 

 soil, both in their growing and in their stored state, together with 

 depredations on live stock, exceed the entire expenditures of the 

 national government, including the pension roll and the mainte- 

 nance of the army and the navy." This loss for the year 1904 

 was estimated at $795,100,000, and this does not include the 

 expense involved in applying insecticides.
