dules enrich 
the soil and 
insure a big 
crop. 
CULTURE—Alfalfa Seed may be sown either in spring or fall at the rate of 12 to 20 pounds per acre. Sow with 
oats, barley or other grains as a nurse crop, sowing only about half the amount of grain per acre, so that the grain 
will not be too thick to smother out the alfalfa. 
Alfalfa is the great hay crop for America and can be successfully grown in many localities. Alfalfa is of two types, 
the Domestic or Common which has a long tap root which penetrates into the soil for a distance of 8 to 10 feet and 
the Grimm Type, which has a spreading root system. The Grimm type is considered the hardiest although on cer¬ 
tain soils and in certain localities the Hardy Common varieties will stand extremes of heat and cold equally well. 
All our Alfalfa Seed is especially selected for Adaptability and Hardiness. 
DOMESTIC ALFALFA —Fancy Domestic High Alti¬ 
tude Seed. Hardy anywhere, high purity and

GRIMM ALFALFA— State Sealed and Certified Seed. 
[ Grimm Alfalfa is the hardiest of the hardy al¬ 
falfas and differs from the domestic or common 
variety in that it has a spreading root system in¬ 
stead of the long tap root which is sometimes 
broken when the ground bulges, during the spring 
freezes, thus causing the plant to die. Highest 
grade seed.

Clovers 
ALS1KE OR SWEDISH CLOVER —Grows well on low, wet 
land where Red Clover does not thrive. Alsike being a 
perennial, will last for a good many years, either for 
hay or in pasture. It makes fine hay of high feeding 
value. It is very valuable in pastures, especially on wet 
or heavy soil. Sow 6 to 10 pounds of seed per acre if 
used alone. Postpaid: Lb., 40c; 10 lbs., $3.50; 25 lbs., 
$ 8 . 00 . 
RED CLOVER, Medium —Colorado-grown seed. This is the 
common Red Clover, so extensively grown. It is a bien¬ 
nial in most places, living but two years if allowed to 
seed. It is usually sown early in the spring on winter 
wheat or with oats or barley, but can be sown in July 
or August quite successfully. Sow 8 to 11 pounds per 
acre. The seed we offer is the highest grade. Postpaid: 
Lb., 35c; 10 lbs., $3.00; 25 lbs.. $7.00. 
KED CLOVER, Mammoth —Also called “Pea Vine’’ Clover. 
This variety grows larger and coarser than the Medium 
and is often used for plowing under to enrich the soil 
for which purpose it is very valuable. American grown 
seed. Postpaid: Lb., 35c; 10 lbs., $3.00; 25 lbs., $7.00. 
LESPEDEZA (Korean Clover) —Korean Lespedeza is an 
annual Legume with very fine stems. In general ap¬ 
pearance It resembles Alfalfa. It grows about 15 inches 
high. Where the stand is scattered the plants branch 
profusely. Where the stand is thick the plants have an 
upright growth like Red Clover or Alfalfa. 
Lespedeza grows on poor soils and increases the fertility 
as well as improves the physical condition of the soil. It 
is an annual but will reseed itself each year so that only 
one sowing is necessary for a permanent pasture. For 
pasture about 8 pounds of seed is required per acre. On 
tilled land for hay or for a seed crop 10 to 12 pounds per 
acre should be sown. Korean Lespedeza is palatable to all 
classes of live stock, particularly cattle. It will stand 
close grazing by cattle and still set enough seed to main¬ 
tain a stand. Postpaid: Lb., 25c; 10 lbs., $2.25; 25 lbs., 
$4.75. 
SWEET CLOVER —The culture of sweet clover is practic¬ 
ally the same as for alfalfa. Sweet clover, however, will 
grow on rough land where alfalfa would not do well. It 
makes an immense growth and if cut before it is too 
ripe makes excellent hay. It is also valuable for pasture 
for hogs, sheep and cattle. Like Red Clover this is a 
biennial and should be renewed every other year. The 
seed may be sown in the late fall and winter, or early 
spring as well as in the summer. For summer sowing 
use scarified seed. Seed not scarified germinates slowly 
and often lies in the ground a long time without sprout¬ 
ing. Sow 12 to 20 lbs. per acre. 
YELLOW BLOSSOM SWEET CLOVER —Is a biennial like 
the White Blossom Sweet Clover and differs from that 
variety only in that it is ten days earlier. Does not grow 
as tall, is more spreading in habit, makes finer hay or 
pasture. Postpaid: Lb., 25c; 10 lbs., $2.25; 25 lbs., 
$4.50.
