Varieties. In spite of the fact that most eastern growers advise inter¬ 
planting of different varieties to insure perfectt fertilization we see no need 
of taking such precautions in Colorado. The Lucretia is practically the 
only variety grown in our best dewberry sections, yet we see no tendency 
toward imperfect fertilization. The variety seems perfectly satisfactory and 
there seems to be litt’e occasion for testing new ones. The Lucretia stock 
varies considerably and could no doubt be improved by proper selection. 
From the literature on the subject it would seem that only one other variety, 
the Mayes, gives promise of equaling the Lucretia. 
Insects and Diseases. So far the dewberry in Colorado is exceptionally 
free from the attacks of insects or plant diseases. No.insects have been re¬ 
ported as doing serious damage. The common leaf spot of the ramblers has 
been observed in on’y a few plantations, and here it seemed to be doing no 
serious damage. The work of this parastic fungus is first indicated by 
purplish spots which appear on the leaves. These spots later dry out and 
tu n a lighter color and show a few dark pustules in the center. Still later 
the diseased tissue may drop out entirely giving the leaf the appearance of 
having been ridd’ed with shot. Should it become necessary to spray for 
this it could no doubt be controlled with one of the standard fungicides. 
Yields and Returns. A dewberry plantation in good bearing will yield 
from three hundred to four hundred crates of berries per acre. Mr. Bald¬ 
ridge’s patch, set on four and one-half acres of ground but with enough 
plants for five acres, was set in 1903. In 1904 it yielded 125 crates of berries, 
in 1905, 1800 crates; in 1906, 1800 crates and in 1907, 2000 crates. It would 
probably be hard to give a satisfactory estimate of the cost of production of 
dewbemies The crate costs the grower 27 cents and picking 35 cents per 
crate, p’us probably 5 cents for overseeing and crat ; ng the fruit. Estimating 
the cost of production at $1.00 per crate this would leave 25 cents per crate 
for other work. With a yield of 350 crates per acre this would mean an 
allowance of $80.50 for other labo". irrigations, cultivating, pruning, cover¬ 
ing, etc. Possibly this is not high enough; but granting that the cost of 
production is $1.25 per crate, which is surely high enough the grower still 
nets a return of $t.oo per crate. At present the average p r ice paid for dew¬ 
berries has been $2.25 per crate F. O. B. the nearest shipping point.

The Loganberry. 
In some of our best berry sections, the Loganberry is sharing popular 
favor with the dewberry. This berry is supposed to be a hybrid of the red 
raspberry and the Western dewberry, and it resembles both. The fruit is 
a’most identical in shape with the dewberry, possibly a little shorter, but 
has the color and flavor of the raspberry; in foliage it resembles the rasp¬ 
berry and in growth it has a trailing habit midway between the two. It has 
the advantage over the dewberry in that the canes stand up better, but it is 
not generally conceded to be as good a producer. When fully ripe the 
berry is a little softer than the dewberry but apparently ships well, and so 
far it has sold for the same prices. Comparison of flavors is largely a 
matter of personal likes and dislikes but in the raw state it is- doubtful 
whether its flavor is as pleasing to most tastes as is that of the dewberry. 
Its flavor is improved by cooking and it makes a very fine sauce. As it is 
grown in a Uni ted way, it is impossible to say whether it will prove as pop¬ 
ular when g'own mo r e generally, or whether the demand is limited. It 
surely deserves a place in the home garden at least. 
Its culture is practically identical with that of the dewberry. The plant 
is a little stronger grower and may profit with a little more room. It is 
possible that the first p“uning may be’ omitted, but. on the other hand, this 
pruning may materially increase the yield by multiplying the number of 
fruiting canes. The fruit is a little harder to pick on account of a tendency 
for the calyces to ck’ng to the fruit. It is picked, packed and handled for 
market as is the dewberry.
