We note that the yield of D 8 is above the average for the plats, 
and not equal to the best plat, we may, therefore, surmise that the 
lessened distance of planting was an advantage. As the yield of D 
5 was decidedly larger than that of D 8, and was far superior in yield 
to the best of the twenty single eye plats, we must consider the ex- 
periment as indicating an advantage from this method of treatment. 
In D 6 we had similar seed, and similar conditions to the above 
named thronghout, with the exception of two single eyes in a hill, 
and thinned; while D 9, its intended duplicate, was treated the 
same in all but the thinning.

In this experiment we see the ill effect of crowding in D 9, by 
the increase of the unmerchantable potatoes, these being over forty- 
three per cent of the total crop, instead of the usual six to seven per 
cent of the single eyes. In D 6 the smail potatoes are but ten per 
cent, and the crop greatly increased. | 
We are thus justified in giving some countenance to the idea that 
we may expect, through thinning our plants to a single stalk, to gain 
increase of crop from single eyes by close planting. 
Moutcurep Potatozs. 
In 1882, through a series of experiments on a quite small scale, 
the hypothesis was suggested that the potato, for its best crop, re- 
quires the tubers to occupy a dry and warm position, and the roots 
a cool and moist position. A small area was covered with six inches 
of sand, another with four inches, the potato seed being Jaid on the 
ground previous to the covering. Under these circumstances the 
tubers were formed in the dry and hot sand bed while the roots occu. 
pied the moist, because mulched, soil below. The yield was,
