The striking point to be noted in connection with Table VIII is 

 the great difference in the rate of moisture loss between sorghum 

 and alfalfa or timothy, as indicated in Tables VIII to XI, inclusive. 



At New London, Ohio, determinations were made of the rate of loss 

 of moisture in timothy cut when in fuU bloom on July 4 and again 

 on July 6. The sky was partly cloudy on July 4 and the temperature 

 was 76° F. at noon. On July 6 the sky was clear and the thermome- 

 ter registered 80° F. at 11 o'clock a. m., 79° at 1 o'clock p. m., and 

 76° at 4 o'clock p. m. In each case the samples were scattered in 

 drying.

The data given in Table IX show that in the first 30 minutes after 

 cutting on July 4 there was a loss of 7 per cent and on July 6 in the 

 same time a loss of 6.1 per cent. In the first hour on both dates the 

 loss was 10.4 per cent, and in 5 hours the loss was 30.4 per cent on
