WHITTEN’S ETTER-VALUE 
GIANT DLUEBERRIES 
Cultivated VasUetiei. 
One of the greatest opportunities ever offered to the fruit 
grower! Get started now with this grand fruit! The best 
money-making proposition that the Nursery Trade has ever 
offered! 
The fruit is large, about the size of grapes, and is borne 
in thick clusters, all over the compact bushes which often 
get 8 feet tall. The enormous size of the berries and their 
unspeakably delicious flavor make them in big demand on 
every roadside stand and commercial fruit market. Every¬ 
body likes Blueberries, in dozens of different ways, so you 
do not need to worry about the market getting slack at times 
as it does with most all other kinds of fruit. 
Cultivated Blueberries require an acid soil, good drainage, 
and moderate supply of moisture. Almost every farm has a 
bit of low, sour soil which does not raise good crops. These 
worthless spots can be turned into real money-makers when 
planted to Blueberries. If you do not have acid soil, this 
condition can be easily induced by mixing with your surface 
soil well-rotted leaves, pine needles, sawdust or soil from 
the bottom of old wood piles. The very best thing, however, 
is our SODUS ACID HUMUS, which is listed at the bottom 
of this page. Write to the U. S. Department of Agriculture at 
Washington, D. C., for bulletin on Blueberry culture. 
We are listing Blueberries in 1-yr. plants, and 2-yr., 3-yr., 
4-yr., and 5-yr.-old bushes. The 3-yr., 4-yr., and 5-yr.-old 
bushes will bear the first season. If you want berries at 
once, plant these larger grades. 
The demand for Blueberry plants so far exceeds the supply 
that we may be sold out of some varieties when your order 
is received. We therefore reserve the right to substitute 
another variety of equal merit, if out of the kind you order. 
We are listing seven varieties as follows: Pioneer, early; 
Rancocas, Harding, Jersey, Concord and Adams in the mid¬ 
season varieties; Rubel for a late variety. 
Rancocas and Rubel are the best commercial varieties, 
being the thriftiest growers and the heaviest producers.

Soilmaster 
Soilmaster is a decomposed, 
concentrated leaf-mold and 
decayed vegetation. This is 
the humus to use on lawns, 
around shrubs and in your garden. Holds seven times its 
weight in moisture, and is a good fertilizer. Rejuvenates 
gardens, lawns, shrubbery and trees; is a natural plant 
food, a natural soil builder; far superior to stable manure, 
has the same fertilizing value, is clean, odorless and does 
not burn; and can be applied any time and anywhere. Is 
ideal for the farm home, garden or suburban home. Requires 
less water after application than other 
fertilizer as it holds moisture for an 
indefinite period. Makes the soil mel¬ 
low and prevents baking. Soilmaster 
goes farther, lasts longer and is more 
economical; two-bushel bag, which is 
approximately 100 pounds, is enough 
for 100 square feet of lawn or 8 good 
sized shrubs or ornamentals. You are 
assured of a three-years' growth in 
two years' time by using this humus. 
Note testimonial. 
Gentlemen: 
Kent, Ohio. 
As a result of our many years spent in the care of 
thousands of fine trees, we know that lawn trees must 
be supplied with artificial food—more especially with 
humus. 
After vigorous tests and use extending over a period 
of 4 years, we are glad to say that Soilmaster has 
proven itself to be an ideal form of humus. Results 
following its use have been uniformly satisfactory 
and at times quite amazing. 
We therefore take pleasure in recommending the 
use of Soilmaster. Inasmuch as it is taken from the 
natural soil deposit, there seems to be no danger of 
overfeeding or burning in its generous use. 
Sincerely yours, 
The Davey Tree Expert Company. 
Signed, M. L. Davey, President. 
Sodus Acid Humus 
Sodus Humus will hold moisture and has the 
same fertilizer value as Soilmaster—the only 
difference between the two is that one is sour 
and the other is sweet. We recommend this 
Humus for Evergreens, Rhododendrons and Blueberries, or any shrub or ornamental that requires an 
acid soil.
