a short time and after they disappear, the 
Black Leaf 40 or Clotragard may be dis¬ 
continued. The spraying of the plants with 
Clotracide must, however, be continued 
every week during the entire season as 
long as the leaves remain green. (Full 
description and prices on Clotragard and 
Clotracide will be found in this catalog.) 
The leaf eating insects, slugs and 
skeletonizers, can be very easily controlled 
by the addition of the Clotragard as men¬ 
tioned above or by adding one heaping 
tablespoonful of Arsenate of Lead to the 
gallon of Clotracide solution. If leaf eating 
insects appear at the same time as green 
lice, both the Arsenate of Lead and Black 
Leaf 40 may be used in the same solution, 
or 4 tablespoons Clotragrad may be used 
instead. We recommend Clotragard for 
both sucking and leaf eating insects, Clo¬ 
tragard being a Rotenone spray, is both 
a contact poison and a stomach poison, 
and therefore takes the place of both 
Arsenate of Lead and Black Leaf 40. 
Clotracide and Clotragrad when used to¬ 
gether make a combination spray that is 
the most effective control for all Rose 
diseases we have ever used here in our 
gardens.

WATERING, CULTIVATING AND FEEDING ROSES 
Roses are living, breathing, drinking, 
eating things and to insure great quantities 
of blooms and to withstand the attacks of 
the insects and diseases mentioned, they 
should be kept well fed, and watered. 
Watering is the most important of all and 
the most neglected. 
Roses as well as other "ground" plants 
require oxygen at the roots as well as at 
the tops. An ideal condition of the soil 
would be one dry enough so the roots 
could get plenty of air and wet enough so 
that the roots could get plenty of water for 
best development. Soil always too wet is 
just as fatal to good, vigorous growth as 
soil too dry. Therefore, proper watering is 
a very difficult condition to- control and is 
the main reason for many failures in grow¬ 
ing Roses and other plants. 
To water properly, run a stream of water 
about the size of a lead pencil into the 
bed all day or all night from a hose with-
