The 4 acres experimented upon was ploughed in February for 
oats ; the seed, potato oats, was put in with the drill on the 
17th March, 1854, the land being in fine condition for receiving

lot No. 1 commenced making the best appearance, lot No. 2 
next, lot No. 4 next, and lot No. 3 considerably behind in 
appearance. Tiie 4 lots continuing that appearance till harvest, 
last harvest being remarkably fine weather, each lot was cut 
* Capable of yielding 13*73 of Ammonia.
