Annual Report of the 
through each of the plats, to carry away water that formerly flowed 
over them all, after heavy rains. 
These plats have been in cultivation to corn during the entire 
four years. The following table gives the yield of each, in bushels 
of ears, weighing 75 pounds:

The yield this year shows the benefit of deep cultivation in dry 
seasons, while the smaller yield last year, on the deeply plowed 
plats, illustrates the injurious results, in a wet season, of deeply 
plowed plats in a retentive subsoil, with no outlet for the superflu¬ 
ous water. 
GRAPES. 
The vineyard belonging to the University Farm has about 900 
Concord vines in the third year of bearing. From these vines, 
there were harvested this year 4,500 pounds of grapes, some vines 
yielding 28 pounds. 
ORCHARD. 
The orchard of 500 trees of a few standard varieties, has made a 
fair season's growth, but few of the trees have borne. 
My thanks are due John Ferry, esq., Superintendent of the 
University Experimental-Farm, for his aid and attention in con¬ 
ducting these experiments.
