 which is quite low. In 1846, it was 71° 05. July was exces-

 much worse in wet seasons than in dry. Some fields were ruined 

 by a worm in the stalk, the egg being deposited by a fly in the 

 extremity of the stem, and working downward in the pith, it 

 wilts and rots, destroying the tubers. It is a new enemy to this 

 valuable esculent. Some fields were benefited by mowing # oft 

 the tops of the vines, and thus destroying the worm. Indian 

 corn, that most valuable and nourishing grain of all the cereals, 

 flourished and grew luxuriantly. It is a plant most admirably 

 adapted to the wants of man and beasts, growing in the United 

 States from their northern to their most southern limits, and when 

 ripe for harvest, remains unharmed in the field for months, to 

 suit the convenience of the grower ; while other crops are lost il
