POTATOES. 



The largest crop of potatoes ever grown in the United States was 

 produced in 18S3. With a small enlargement of area the yield ad- 

 vanced from 78 to 1)1 bushels per acre, making a productof 20S,1G4,425 

 bushels, or thirty-eight millions in excess of the previous crop. The 

 average yield per acre for a series of years, as estimated and recorded, 

 is 84 bushels. 



The effect of last year's abundance was to reduce the price from 57 

 cents for the previous crop to 42 cents. 



HAY. 



A marked increase of area in meadows was reported of over three 

 millions of acros, and the conditions so unfavorable to wheat were es- 

 pecially advantageous to grass. The yield was therefore increased from 

 1.18 to 1.32 tons per acre and the product was the largest ever reported, 

 40,864,009 tons. 



METEOKOLOG IOAL INFLUENCES OF THE SEASON. 



As has been hinted above, there was a deficiency of heat for early 

 maturity of maize in the belt of principal production, and for the de- 

 velopment of other summer crops, and in some districts an excess of 

 moisture in the planting season. The study of the influence of tem- 

 perature and rainfall on production is important in explanation of the 

 causes producing obvious results, and the following tables, compiled 

 from Signal Service records, are presented for the purpose of facilitating 

 such investigation.
