Experiments on Lawns,

which could be advantageously obtained, or rather what was the 

 largest quantity which could be profitably employed as manure. 

 It is evident that this experiment was not carried out quite far 

 enough as the maximum of produce was not obtained. No. 38 to 

 which 240 gallons of Gas liquor, equal to 300 lbs. of Sulphate of 

 ammonia, was applied, produced a far better crop than No. 39 which 

 received 200 gallons or 250 lbs. of the salt : the increase of grass 

 being in a much greater proportion than the increased quantity 

 and cost of the manure. There appears to be little doubt that in 

 situations where Gas liquor can be had readily, and applied without 

 difficulty, it is preferable to Sulphate of ammonia ; but on the other 

 hand, the latter, though rather more expensive, can be spread more 

 easily, and is far less costly in carriage.
