D. 17 yielded 17.2 ozs. and D. 19 yielded 11.4028. The average for

We hence see that our results of trial have no special significance. 
EOTATO WAG. 
The rot has been quite severe with us this year. ‘The average rot 
in thirty-four plats of one twentieth of an acre each was 65 per cent. 
of the total crop, by weight, the least being 52 per cent. the great

In the five plats, D. 1, 2, 5 and 6, treated with a ton of fertilizer

By this we may infer that the rot is neither caused nor intensified 
by the fertilizer. 
FERTILIZER ON POTATOES. 
Under the same amount of fertilizer, viz. 400 lbs. per acre, and 
the conditions in all respects alike, so far as under our control, there 
was much variation which can be sought to be explained by the con- 
dition of the land as regards fertility, but unfortunately for this easy 
solution, the testing of the land by previous crops does not show the 
relation ‘between the size of crop for the two years that would be so 
comforting to the theorist. We present the average and extreme 
yields from twelve plats upon which 400 Ibs. phosphate per acre was.
