the oak abounds they are cheaper than bark, and, if 

 properly managed, they yield heat more permanently. 

 After being raked into heaps, the leaves should 

 immediately be carried to some place near the hot-

 house. In getting them into the pine pits, if they 

 appear dry, water them again, treading them in 

 layers exceedingly well till the pits are quite full. 

 Then cover the whole with tan to the thickness of 

 two inches, and tread thoroughly till the surface be-

 After this, the leaves require no farther trouble the 

 whole season through, as they will retain a constant
