RED RASPBERRIES. 
• Only very brief descriptios are given of the following varieties of rasp¬ 
berries on accout of the lack of space; these are given in their order of im¬ 
portance. 
Marlboro. —This variety is of only ordinary quality but noted for their 
firmness both on the bushes and hold up well in shipping. 
Cuthbert. —A good berry for home use, having fine quality but generally 
too soft for shipping long distances. 
Loudon. —Canes vigorous, quite hardy, and productive. A good berry 
for local market or home use. 
Turner. —This variety is very hardy and vigorous. Fruit, sweet and of 
excellent flavor. 
Golden Queen. —In all characteristics this is a Cuthbert except that it 
bears yellow fruit. A few for home use are desirable. 
BLACK-CAP VARIETIES. 
Gregg. —Best known late variety. Very good shipper and an excellent 
variety for evaporating when picked by hand. 
Kansas. —Fruit similar tp Gregg ripening a week earlier, juicy, of excel¬ 
lent flavor and firm enough to ship well. 
Ohio. —The great evaporating raspberry of the present day. Quality 
poor as it is very seedy but yields more pounds of evaporated fruit per 
bushel than any other sorts. 
PURPLE CANE VARIETIES. 
Shaffer. —An excellent canning variety. 
Philadelphia. —This represents the red raspberry more closely than 
some of the other purple cane varieties. Propogated by suckers, yields 
but sparingly. 
Columbian. —This is of the Shaffer type and ripens a little later. 
PROPAGATION. 
Propagation of the raspberry varies according to which species 
it belongs. The red raspberries are propagated from the suckers 
which come up from the parent root. As a rule most of the red va¬ 
rieties throw up enough suckers to insure plenty of young plants. For 
this reason careful cultivation has to be resorted to in order to avoid 
injuring the root system of the old plant. . For when it is injured it acts 
only as a stimulant to throw more shoots and often requires a severe 
pruning to keep them down. The old plant can be separated by di¬ 
vision thus obtaining extra plants for planting purposes, but as a rule 
this is not as good a plan as to use the young shoots with the roots at¬ 
tached. 
The black raspberry is propagated by tip layerage. This is done by 
covering the tips along the latter part of July or the first of August. 
They take root at this point and generally establish themselves well 
enough so that the next spring they can be separated from the par¬ 
ent stock by cutting the cane off near the ground. 
The purple cane varieties vary somewhat in their mode of prop¬ 
agation according to the variety. The most of them however resemble 
the black-cap in this respect and are propagated by tip layerage.
