COLORADO EXPERIMENT STATION 
Varieties. In spite of the fact that most eastern growers advise inter¬ 
planting of dififerent va’deties to insure perfect fertilization we see no need 
of taking such precautions in Colorado. The Lucretia is practically the 
on’y variety grown in our best dewberry sections, yet we see no tendency 
towa’'d imperfect fertilization. The variety seems perfectly satisfactiry and 
the-e seems to be little occasion for testing new ones. The Lucretia stock 
var’cs 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 Co’o“ado is exceptionally 
free from the attacks of insects or plant diseases. No insects have been re- 
po"ted as doing serious damage. The common leaf spot of the ramblers has 
been observed in only 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 
turn a b'ghter color and show a few dark pustules in the center. Still later 
the d scased tissue may drop out entire’y giving the leaf .the appearance of 
having been riddled with shot. Should it become necessary to sp"ay for 
this it could no doubt be controlled with one of the standard fungicides. 
Y.elds 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 yie’ded 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 
dewberries. The crate costs the grower 27 cents and picking 35 cents per 
crate, plus nrobab’y 5 cents for overseeing and crating the fruit. Estimating 
the cost of production at $1.00 per crate this would leave 25 cents per crate 
fo- olhe’* work. With a yield of 350 crates per acre this would mean an 
allowance of $80.50 for other labor, irrigations, cultivating. p:'uning, cover¬ 
ing etc. Possibly this is not high enough; but granting that the cost of 
production is $1.25 per crate, which is sure’y high enough, the grower still 
nets a rctirm of $t.oo per crate. At p-esent the average price paid for dew¬ 
berries has been $2.25 per crate F. O. B. the nearest shipping point. 
The Loganberry. 
In som'e of our best berry sections, the Loganberry is sharing popular 
favor with the dewberry. This berr}' is supposed to be a hybrid of the red 
ras]ibcrry and the Western dewberry, and it resembles both. The fruit is 
almost identical ni shape with the dewberry, possibly a little shorter, but 
has the color and flavo:- of the raspberry; in foliage it resembles the rasp¬ 
berry and in g-owth 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 conceeded to be as good a producer. When fuTy ripe the 
be"ry is a little softe:- than the dewberry but appa"ently ships well, and so 
far it has sold for the same prmes. 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 imp"oved by cookbig and it makes a very fine sauce. As it is 
grown in a lim'ted way, it is impossible to say whether it will prove as pop- 
u’ar when grown mo"e generally, or whether the demand is limited. It 
surely deserve a place in the home garden at least. 
Its culture is practically identical with that of the dewberry. Th(^ plant 
is a litt’e stronger grower and may p"ofit with a little more room. It is 
possible that the first p^unmg may be omitted, but, on the other hand, this 
pruning may materially increase the yield by multiplying the number of 
fruiting canes. The f 'uit is a little harder to pick on account of a tendency 
fo- the calyces to cling to the fruit. It is picked, packed and handled for 
market as is the dewberry.
