GREAT CROPS OF STRAWBERRIES AND HOW TO GROW THEM

WARREN, ONE OF THE BEST OF THE EARLY VARIETIES 
QNE of the recent originations that belong in the high-quality class. The late S. H. Warren of Massachusetts never origi- 
nated a poor variety in his long experience as an originator. To use his own words, his last origination was his best origi- 
nation. The Warren" is an exceptionally heavy yielder of large, luscious, higly-colored and uniformly shaped berries. The 
plants are exceptionally vigorous with strong, leathery foliage of very dark green. The calyx is of light green and adds great- 
ly to the productiveness of this variety. This variety won the silver medal of the Massachusetts Horticultural Society in 1912. 
This is a notable honor because there is no other society in the United States whose medals are moi-e highly prized. This un- 
usual distinction of itself is a guaranty of preeminence as to quality and fruiting power. Grown only at our Three Rivers farm. 
pistils of the female or pistillate varieties) there 
would be little fruit of any kind produced. This 
law of the sexes relates to all forms of vegetable 
life. J. H. Hale the world's peach king finds, 
for instance, that when the Elberta peach tree 
is set in close proximity to the Hale peach tree 
the crop of Elberta peaches is largely increased, 
as a result of the pollen supplied to its bloom by 
the Hale tree. Just as important is the pollen- 
ation of the strawberry bed. And therefore we 
ask your especial attention to what we have to 
say on that point, which we shall try to make 
very clear to the beginner in strawberry culture. 
First. Remember that Bisexual varieties com- 
prise in their own constitution both sexes; that 
is, male and female are combined in one plant 
and therefore they are perfect-flowering plants, 
requiring no mating in order to produce large 
crops of fruit. The word bisexual means two- 
sexes, or a plant having both stamens and pistils. 
The importance of proper mating may not be 
overestimated. 
Second. Remember that all Pistillate varieties 
must be mated if one would secure a full crop of 
fruit, as these plants secrete no pollen whatever 
and depend for fertilization of their bloom upon 
the bisexual plants. 
Third. While the bisexuals will yield large 
crops of fruit without mating, our experience of 
many years convinces us that it is better to set 
several varieties of bisexuals, as the exchange of 
pollen between bisexuals is beneficial and encour- 
ages still larger yields. 
All varieties in this book that are marked ( B ) are 
bisexual and are self-fertilizing; they also ferti- 
lize the bloom of the pistillate varieties. All 
plants marked (P) are pistillates and must be ma- 
ted. The better way to mate a pistillate variety 
is to place one row, or two rows, or as many as 
three rows, if so desired, of pistillates between 
rows of an early and a late bisexual. Take, for 
instance, the greatest of the pistillates — our Kel- 
logg's Prize. An ideal arrangement for this pis- 
tillate variety would be to place the Kellogg's 
Prize between rows of Kellogg's Premier and of 
a late bisexual such as Pearl or Chesapeake, or 
Joe Johnson. In this way both the early and the 
late bloom of Kellogg's Prize will be perfectly 
pollenized. You may set one row, or two rows, 
or three rows of Kellogg's Prize between the bi- 
sexuals as suggested. 'That is to say, pollen will 
be perfectly distributed over at least three rows 
of pistillates when such an arrangement is made 
as is here indicated. Please remember that this 
is simply an example given to show the proper 
mating of all pistillate varieties, and you may set 
any pistillate on our list between bisexuals of 
your choice and be sure of securing a full crop of 
fruit from the pistillate as well as from the bi- 
sexual varieties. 
We shall always be glad to give special infor- 
mation regarding the mating of different varie-
