 begins to gain ground on the powers of life, and

 it. This may be a difficult tafk, but is neceflary, 

 as life entirely depends upon it. 



Heat, though lefs frequently an object of our care 

 in this refpect than cold, neverthelefs demands our 

 attention. Though feldom of long duration, the 

 heat is fometimes exceflive. I have feen it in the 

 (hade, and in a fituation expofed to no reflected

 laborious work even in the (hade, and mud be dill

 rays, which is of neceflity the cafe with thofe who 

 work in the harveft.
