EXPERIMENTS WITH POTATOES.

4. That the best culture of this plant requires that 
it be kept doing its best during the growing season, and 
not allowed to suffer a check, the result of which is 
supertuberation and the presence of ugly excrescences 
on the tubers. 
5. That it is of importance in the care of seed to 
avoid its starting into growth too early in Spring, and 
the shriveling of the tuber before planting. Keep intact 
the main shoot from each eye. 
6. That no rule can be laid down as to quantity or 
frequency of irrigation needed to mature this crop. 
Each must decide for himself, according to the character 
of the soil, its location in reference to seepage, the rain¬ 
fall during the growing season, etc. 
7. That in regard to varieties, the most desirable 
are such as produce medium-sized tops, bear their tubers 
close in the hill, necessitating deep planting, and show¬ 
ing a breeding in favor of the maximum early develop¬ 
ment of tuber, with a minimum vigor of top. The kinds 
making a good exhibit this year may be depended upon 
as being prolific croppers, particularly on soils adapted 
to the best culture of this plant. 
8. That the fertilizer experiment exhibits nearly a 
doubling of the crop in favor of bone meal. That the 
use of land plaster gave an increase of over thirty bush¬ 
els per acre over the bone superphosphate and clay kal- 
somine. 
EXPERIMENTS WITH TOBACCO. 
Experiments have been conducted at this Station for 
the past two years with varieties of tobacco sent out by 
the Department of Agriculture, Washington, D. C. 
The work done in 1886 was on too small a scale to de¬ 
termine definitely the question as to its availability as a 
farm crop in this State.
