GREAT CROPS OF STRAWBERRIES AND HOW TO GROW THEM

GLEN MARY FURNISHES A SUMPTUOUS REPAST 
"pHIS notable mid-season variety is loted for its heavy yields of big, dark-red berries, and its popularity increases with each 
* succeeding season. Prominent seeos of bright yellow make a fine contrast with the dark red of the fruit, and this is a par- 
ticularly attractive combination when the berries are placed on the market. The meat is crimson, juicy and rich and of un- 
usually high flavor. As a shipper it is excelled by no other variety and consequently is grown very extensively by commercial 
growers. The Glen Mary has a powerful root system and very large foliage and it is especially popular in sections of limited 
rainfall. This is the eighteenth year we have carried this extraordinary variety in our list and the popular demand increases 
with the years. Glen Mary and Wm. Belt mak a very fine combination. Grown on both Three Rivers and Twin Falls farms. 
the winter period, when the ground is not frozen, 
and in the spring it starts up very early and 
grows with great rapidity. Be careful that the 
winter vetch is thoroughly matured. In order to 
secure best results we never plow under the vetch 
until it is in full bloom. The plowing under of 
the mass of organic matter contained in the 
clovers and vetches restores, as we say, the soil 
to its original state of fertility. 
We realize that in the case of many of our cus- 
tomers it will be found inconvenient to manure 
their ground during the winter, and we, therefore, 
suggest the following plan when the soil can be 
prepared only in the spring and just before plants 
are to be set out. Under these conditions we ad- 
vise that the soil be plowed as early in the spring 
as conditions will permit. Before plowing spread 
evenly over the ground from ten to twelve two- 
horse loads of manure per acre, mixing it thor- 
oughly into the soil with spiked-tooth, or spring- 
tooth, or Acme harrows, or with the disc. If the 
soil is very loose, it should be made firm with 
either roller or float. Or, you may plow your 
ground and make the soil flne and firm and then 
scatter well-decayed manure between the rows of 
plants after the plants have been set. Any of 
these methods will give you the desired results. 
Regarding Commercial Fertilizers 
ly^ANY growers depend entirely for their fertil- 
* ity upon commercial fertilizers. Where this 
is necessary the fertilizers may be purchased in 
prepared form, or the materials may be bought 
and mixed by the grower. Nearly all companies 
who prepare commercial fertilizers for the mar- 
ket make a brand particularly adapted to straw- 
berry growing, and will give information for the 
use of their fertilizer. We believe, however, that 
it is best to mix one's own fertilizer, and the fol- 
lowing formula will serve, especially where straw- 
berries are grown: 150 pounds sulphate of pot- 
ash, 200 pounds of dried blood and 400 pounds of 
acid phosphate or bone meal. This 750 pounds of 
mixed fertilizer will be ample plant food for one 
acre. This commercial fertilizer should he ap- 
Elied after plowing and worked well into the soil 
efore the plants are set out. It always should 
be remembered that whatever fertilizer you use
