 seedsman, and if manure can be obtained, domestic 

 cultivation might be much more common than 

 it is. We have heard of a crop being grown in a 

 hatbox, and we have seen them flourishing under 

 the shelves in a greenhouse. Of course, some per-

 should be now and then turned for sweetening. 

 After this has subsided to moderation it will be in

 hand ; if not found violent, the spawn may be broken 

 up into pieces of two or three inches square, and put 

 into holes about three inches in depth, by six inches 

 asunder, over its surface ; after this, throw a very
