The upper layer may be used advantageously as bedding 

 and as an absorber of liquid manure ; the lower layer ought 

 to be composted with lime or ashes before it is incorporated 

 in the soil. Both samples are of a good quality.

The ashes were obtained from the burning of the surface 

 growth of a swamp meadow lately in part underdrained. 

 Bogs, tussocks, and a few inches thickness of the turf, fur- 

 nished the ash. The dried-up condition of the vegetable 

 matter explains the presence of but a small quantity of pot- 

 ash. The ash may prove beneficial upon adjoining grass 

 lauds.
