On the Cultivation of the Pine Apple. 389 



rows till the latter part of January ; afterwards water was given 

 as usual, and in February several fruit began to appear ; the water- 

 ing was then withheld from the other rows for a time, in order to 

 bring them on in succession. In order to obtain bottom heat to 

 swell my fruit off, I resolved to take out the two front rows and pot 

 them, taking out the oak leaves to the bottom of the pit; the 

 space thus occasioned I filled with well-fermented horse dung, and 

 covering the latter with tan, I again plunged the two rows of 

 plants I had potted. The horse dung that I put in gave me 

 sufficient heat to swell off my fruit to a great size. I should add 

 that the surface of the soil was covered with moss, which I am per- 

 suaded was a great help in keeping the soil in a humid state with- 

 out the aid of so much water. 



I am, Sir, 

 your most obedient Servant, 



George Warren.
