  if THE So1L.——The soil is derived from the Lower
ii. s Silurian limestone, and is rich in phosphoric acid. The
  land is worn, having been in cultivation many years.
Vi The subsoil is a light-colored clay, so retentive as to
. p · ' make the soil deficient in natural drainage.

4, . - ’ soil-elements besides these, and they are just as essential
i   ’ i to plant life as these three, but generally speaking all but
f , these ingredients are furnished to plants in abundance,
L` and therefore in studying what to put on our soils to
[ make them more productive, we need concern ourselves _
2 ‘ with only these three. Commercial fertilizers are manu-
, . factnred and sold for the purpose of supplying nitrogen,
< Q, phosphoric acid and potash, and the market prices de-
5,_   . _ pend upon these ingredients. Some fertilizers contain
` X * one of these ingredients, some two, and some all. Gen-
erally speaking, a commercial fertilizer is a mixture con-
taining two of these ingredients, and sometimes all, the
i'~ proportions varying greatly in the various brands and
Qp often in the same brand. lt is at once seen to be a very
  `Qs. difficult, if not an impossible task, to test all the various
l   brands sold on a given soil in order to find out those that
i produce the best effect. lt is an easy matter, however,
to hud out whether a given soil needs potash, phosphoric
_ _ acid or nitrogen or any combination of these elements for
  . a given crop. Having found out this by experiment. we
e havegonly to look to the analyses of the various fertilizers
i to tell which brands. if any, could be used to advantage
r on the soil and crop tested. If the experiment proved
» that potash was all that was needed on a given soil for
the corn crop, all those fertilizers whose analyses show
little:or,no potash would not produce favorable results,
r under whatever name sold.

tr The Experiments.
S The potatoes used for seed were Northern grown Early i  
S` Rose. They were immersed for % hour in a solution of ’ ,
O mercuric chloride before being planted. This solution  
contained 3,% ounces of corrosive sublimate (mercuric , .
te chloride, or bichloride of mercury) to go gallons of water. , !
ar After drying, the potatoes were cut and planted. (As the
al above solution is poisonous, the work of treating the po- l
it tatoes with the solution should never be done where stock
e, might get to the solution or the treated potatoes.)
to The size of the experimental plots was 1-10 acre each.
es _ After the ground was well prepared with plow and har-
u- row, the rows were marked out with a small plow. The
n, fertilizers used were scattered in the row by hand and
e- afterwards slightly mixed with the soil by a brush being V
in dragged along in the row.
n- The fertilizers were applied and the potatoes planted

  ._ From the results obtained it would appear that both
  i potash and nitrogen are needed on our soil, for potatoes;
·¤ — that potash alone greatly increases the yield; that nitro-
T, gen does to some extent, but that the best results are ob-
1 tained by a combination of the two. Trials for six years
{ ~ V have shown that potash greatly increases the yield of po-
, _ _ tatoes, when applied to our soil.
L l That this is not true for all soils is demonstrated
i   . — by the experiments of Mr. Thos. R. Walker, of ]unction
’ "i ’ City, Boyle Co. His results show that phosphoric acid
f is the element needed on his soil. Below are given the

  ‘· chief. It is a very small, black insect,* with the body
  Y rather thickly clothed with very fine erect hairs. The
  I division of its body just behind the head is coarsely and
closely punctured, so that the surface has an opaque
_ appearance. It is a rather compactly built little beetle
1 I i about 0.09 inch long. When disturbed, it leaps from the
l - , leaves by means of its thickened hind legs.
i ` Sometimes this insect riddles leaves of potatoes with
. 41,.; . very small round holes, an injury which checks the
> i growth of the plants. In 1889 the writer found that the
p I use of Bordeaux mixture was a very useful remedy for
‘ this insect, and published a note to this effect in Agricul-
_   tural Science, volume 6, 1892. More recently it has been
` recommended for the Eastern fleabeetle (Epi!rz;r mmm-
    erzk) by Professor L. R. jones, of Vermont Station. Dur-
`_   ing the past summer its injuries were observed to be
ll` ill V ‘ checked by a combination of Paris green and Bordeaux
flu mixture, or by the former alone.

Injury by Small Mammals}
S Still another injury noted in our plots was due to some
_;_ small mammal, probably a field mouse. The marks of
_ i the teeth are very plain in many cases, and occasionally
‘· the greater part of a potato is devoured. The mole has
been accused of this latter mischief. But it guilty he
_ certainly pays for all the potatoes he eats by destroying
white grubs and wire-worms. An examination of the
stomachs of I4 moles (See our Annual Report for I8€)J,>»
collected mostly on the Experiment {arm, shows that
» this animal depends very largely for Food ou earthworms
and insects, and that it is especially fond of white grubs.

Potatoes. 23
Since my paper on the food of the mole was printed I l I
have chanced upon a published observation on this point
that bears out my conclusion as to the generally in- f I
sectivorous and useful character of the mole. In the ·
Canadian Entomologist, volume 14, page 17, Professor l
E. W. Claypole, writing from Yellow Springs, Ohio, } ,
says: " In digging potatoes this year I observed the , I
runs of a mole in all directions through the ground.
It was a piece of old sod, and very much infested r
with white worms, the larvw of the cockchafer (Lach-
vzosxermz j%sm). Many of the potatoes had been part-
