the upper ; the heat naturally mounting up- 
wards, and' remaining hot longeft towards 
the top ; befideSj by leaving the upper half 
imfpawned and un-earthed, the heat from be- 
low if It fhould prove a little too ftrong, finds 
vent above ; but in about a week’s time 
fpawn it wholly : the lower part having a 
week’s advanced growth, will probably fur- 
nilh a fmall gathering fome days before the 
upper half. 
However, in general, after having ob- 
ferved the neceffary precautions juft given, 
take the firft opportunity to perform the 
fpawning, lofing no time for the bed to ex- 
hauft itfclf ineffedtually without being planted. 
Let the fpawn be brought forth in a dry 
day, and be careful that it is tolerably dry in 
jtfclf j proceed to plant it in pretty middling 
lumps ; not feparating the fpawn, from the 
^ lumps
