A SINGLE HILL OF KELLOGG'S PREMIER IN FULL FRUIT 
BEFORE this hill was photographed, most of the leaf stems were removed so that the berries would be exposed 
to the camera. You will note that this hill is loaded with buds, blossoms, and berries in all stages of develop- 
ment. To give you an idea of the size of this hill and berries, let us say that the hill was nearly as large as a bushel 
basket. If the full size and true color of these berries could be shown, you would agree with us that Kellogg's 
Premier is the greatest of all extra-early varieties, and that plants of this variety are cheaper and more desirable 
at $10 per thousand than plants of any other extra-early variety at $3 per thousand. 
large crop of strawberries with only one-half the 
required amount of fertility. We refer to straw- 
berries as being grown, which in a sense is true, 
but in reality, they are built from materials 
which go to make up a strawberry. Nature does 
the building; we supply the building material, 
and the more material we supply, the more straw- 
berries nature will build for us. The materials 
employed by nature in building strawberries are 
nitrogen, phosphorus, and potassium, and if these 
elements are supplied, nature will not disappoint 
us. 
Fortunately, most soils contain a sufficient 
amount of phosphorus and potassium, which 
makes it necessary for us to supply only nitrogen 
and humus. The most economical way of supply- 
ing these requirements is either through stable 
manures or any of the legume crops, such as cow 
peas, soy beans, vetch, clover or alfalfa. Here- 
tofore, we have recommended the use of acid 
phosphate or bone meal for the phosphorus, and 
sulfate of potash for the potassium, but on ac- 
count of the European war these materials have 
become very expensive; in fact, their high cost 
at the present time makes it unprofitable to use 
them. For this reason, we have experimented 
with manure alone, with results equally as good 
as when we used the commercial elements. We 
also have experimented by plowing under clover, 
vetch, and alfalfa, without the use of any manure, 
and the results of these experiments convince us 
that when manure cannot be obtained, these 
legumes take its place with very good results. 
When we plow under either stable manure or a 
legume crop, we increase the bacteria in the soil, 
which in turn liberates the phosphorus and po- 
tassium which nature has stored there. 
To make one acre do the work of two, we should 
apply to that acre not less than twenty two-horse 
loads of stable manure or plow under a legume 
crop. Fall plowing unquestionably gives the best 
results, but when this cannot be done, plow as 
early in the spring as soil conditions will permit. 
When soil is plowed in the fall and manured in 
the winter, and replowed in the spring, it natu- 
rally is in better condition than if plowed only in 
the spring. But whether you plow in the fall or 
spring, don't fail to pulverize the soil finely be- 
fore setting out the plants, and if the soil is of a 
loose nature, it should be rolled quite firmly. 
This pressing down of the soil may be done either 
with roller or float. Floating or rolling binds
