of soda. 5th season (commencing in 1858). 
Plot 16. 14 tons farmyard manure. 
Plot 17. 14 tons farmyard manure, and 200 lbs. ammonia salts. 
The first crop each year has always been mown for hay, and 
the after-grass eaten off by sheep, once or twice as might be 
required, a certain number, according to the amount of grass, 
being folded on each plot, and the number of days occupied in 
its consumption noted. 
Produce of Hay per acre {First Crop'). 
In Table I. (p. 530) are given the quantities of hay obtained 
per acre (first crop) from each plot in each of the four years, 1859, 
1860, 1861, and 1862; also the average annual produce, and 
average annual increase by manure, over the four and over the
