REPORT OF THE COMMISSIONER OF AGRICULTURE. 



PRODUCTION AM) EXPORT OF CORN AND WHEAT. 



The object of Diagram XXI is to present to the eye a comparative 

 view of the recent production and exportation of corn and wheat, to 

 illustrate the preponderating volume of the one and large proportion 

 exported of the other. The period is seven years of plenty, in which 

 ihe average estimated product of corn is 1,510,000,000 bushels, and of 

 wheat 436,000,000. There was exported in this period an average of 

 72,000,000, while of wheat the exports averaged 141,000,000. This left 

 for consumption an average of 1,438,000,000 of corn and 295,000,000 of 

 wheat. This gave, for bread and seed, nearly G bushels of wheat per 

 capita. The ligiues are as follows*

PRODUCT AXD EXPORT OF CEREALS. 



Diagram XXII compares the production of cereals in 1879 with the 

 exportation from that crop between July 1, 1S79, and June 30, 1880. 

 The squares which represent the quantities produced of the several 

 grains are drawn to a scale of 3,000,000 bushels per square inch. 

 The design is to present to the eye at a single glance an idea of the 

 respective volumes of the different crops and the proportions of each 

 exported. Every one who knows the facts is aware of the great pre- 

 ponderance of the corn crop ; but there are few to whom the exact pro- 

 portion, presented so clearly to the natural eye, does not prove a rev- 

 elation to the mental vision. It is seen that the maize makes a larger 

 show than the other five combined, and that the three minor crops, 

 barley, rye, and buckwheat, taken together, only make 3 per cent, of 

 all. The proportions are thus shown in figures:

PRODUCT PER HEAD OF ALL CEREALS. 



The, design of Diagram XXIII is to show the comparative produc- 

 tion of cereals in Europe and in the United States. The latest avail- 

 able statistics of annual production are used. The European average 

 is 16.1 bushels per head; that of the United States more than three
