D. 1t may he broadly stated that tho
weight at the cropis prnportionate to the
weight per acre OF the sets, nnd that snail
sets VIII produce the same crop as an equal
weight per acre of lnrgc scts. The fact il,
however, of limited application. Ms II weight

sized potatoes, could not he got into the
ground, except by planting them so close ns
to be prtjudcal to the crop. The adyan.

q. Weight for weight. cut scts produce az
nearly as possible the same weight per acre
as whole potatoes, but. for the reasons given
above, the weight of the sets should not be
reduced by subdivision.
I. smaller sets give larger produce in
proportion to their weight than ,ae larger
sets.
.. When the intervals between the scts in
rows are diminished to less than foot. the
produce of each individual set is propor
tionatey diminished. Though this is no.
necessarily accompanied by a diminution of
the weight Of the crop. no increase in tho
produce of each individual set is caused bv
placing the sets at intervals wider than =
foot

precedence throughout the experiments; and
"I the several varieties of Flnke, "Spencer's
King of Flukes, 'and"The Queen nf Flukes,"
are much more prolific than the ordinary
variety.
As 10 the manure best aGapted 20 tho po
tato, 1t Was found by DR.. Lang that all nj
trogenous dressings tried in Devonshirr
were rather preiudcul than otherwise, rs
regards the potato disease, but that wood
and salt were beneficial.
Experiments with regard to manures wore
carried on under the direction of Prof. Voc
lekcr. and on examining them the following
deductions have been made: .
]. The best crop was Obtained by the usc
OF rotten harnyard manure
.. Super phosphate and crude potash salts
"A purely mineral manuring gave n nearly
equal increase. The mixture OF superphos-
phatc and crude potash salts appear to I've
specially useful for root-crops on light land
g. Common salt enhances the efficiency of
the supcrphosphate and potash salts, bn.
when used alone it slightly diminishcs the
crop.
T. Potash sal.s applied alone though by
no means the most desirable manure fnr
p"tatoes, nevertheless had a better effect
than common salt for while the crude pot
ash-salts gave an increase OF nearly G cwt.
per acre, common salt produced : cwt. and
a. lbs. less than the unmanurcd plots, on the
average.
