GREAT CROPS OF STRAWBERRIES AND HOW TO GROW THEM 
Copyright 1915 by R. M. Kellogg Co., Three Rivers, Mich. 
A TEMPTING DISH OF ADVANCE (EVERBEARING) BERRIES 
AS we say in referring to Onward and Forward so we can say with regard to Advance, the similarity between Forward. On- 
ward and Advance is so marked as to render a description of one of this great trio serve for all. We advise all our custom- 
ers however to try out all three of these varieties, as under different soil and weather conditions there doubtless will be consider- 
able variation. All three of these varieties are tremendous growers of fruit from June to November. Grown at Three Rivers. 
worry stage so far as a competency is concerned. The 
fact that your book is doing a work of this kind should 
be of some satisfaction to you. 
It certainly is of large satisfaction to us. The 
ideal of service that directs the work of this 
company and enters into its every feature, ex- 
tends a helping hand to all who wish to enter the 
strawberry field. And as the strawberry field is 
one that the novice and the moneyless may enter 
with complete assurance of success, wherever 
ordinary intelligence is practised, the field is 
vastly broad and inviting. We need not say that 
we greatly appreciate the kind thoughtfulness 
that led Mr. Utley to write us as he has done. 
CUSTOMERS always should use the same name 
in writing about orders. For instance, if John 
Smith orders plants any further correspondence 
relating to that order from him should be signed 
in his name. Should his wife write and sign 
"Mary Smith" we could not be sure that her in- 
structions related to John Smith's order. By 
using one name throughout, confusion may be 
avoided. 
How Strawberries Are Made 
CONTINUOUS cropping of the land without 
proper crop rotation causes the soil to become 
acid and unproductive. Where this condition 
exists the desirable bacteria become logy and 
inactive, while the undesirable bacteria become 
more active, which aids them to get control of 
the desirable bacteria. 
There is a battle going on at all times between 
desirable and undesirable bacteria. Therefore, 
in order to get the greatest profits from our land 
we must make conditions favorable to the desir- 
able bacterial germs. 
From two to four tons of finely ground raw- 
rock limestone per acre will correct the acidity 
of the soil. It also will greatly aid in releasing 
plant food which otherwise would remain as inert 
or useless matter. Lime may be applied during 
the winter months when the farmer has plenty 
of time for that kind of work. 
To learn if your soil is acid, take a strip of 
litmus paper, which may be purchased at any 
drug store, make an opening in the soil with a 
knife or hoe blade and place a strip of litmus 
paper down in the moist soil, press the soil firmly 
against the paper, and in fifteen or twenty 
minutes remove the paper, and, if it has turned 
a red color, your soil is acid. The degree of red- 
ness will determine the degree of acidity. 
One ton of unleached hardwood ashes or two 
tons of marl per acre will serve the same purpose 
as the lime. Wood ashes also will add potassium, 
which is very beneficial to strawberries. 
Nitrogen gives the plants vigor and stamina. 
All green matter, such as stems, leaves, etc., is 
largely developed by nitrogen. In fact, the entire 
plant is dependent upon nitrogen. This im- 
portant element may be added to the soil through 
many different sources, such as manures or 
legume crops— clover, alfalfa, vetches, cow peas, 
soy beans and sweet clover. In commercial 
forms nitrogen is secured through dried blood — 
200 pounds per acre; or sulfate of ammonia— 150 
pounds per acre; or nitrates of soda — 100 to 200 
pounds per acre. The latter is generally used as 
a top dressing. One hundred pounds per acre 
scattered along the fruiting rows when growth 
starts in the spring and 100 pounds applied just
