Mushroom Spawn 
Cultural instructions for growing mushrooms given free 
to every purchaser of spawn. 
BERT’S PURE CULTURE 
—This spawn is specially pre¬ 
pared for us and produces 
results where the average 
spawn proves a failure. It is 
a strong strain of spawn 
thoroughly acclimated and se¬ 
lected with reference to earli- 
nesS, size, flavor, appearance, 
prolificacy and quality of the 
mushrooms that it will pro¬ 
duce. We highly recommend 
this spawn for those who in¬ 
tend to raise mushrooms for 
the market. 
Bricks 40 cents each (5 bricks $1.76), Postpaid. 
Onions 
(Cipollo, Cebollo, Zwiebel) 
CULTURE—One ounce of seed is sufficient for 100 feet 
of drill, 4 pounds for one acre. Onion seed should be sown 
as early in the spring as possible to get the ground in shape, 
even though the weather is cold. Thorough preparation of 
the soil is one of the most essential points in successful 
onion growing. They delight in a rich, deep sandy loam, 
but excellent yields can be obtained from heavier soils 
properly fertilized. Sow the seed in rows 12 to 14 inches 
apart and about inch deep. After they are well started, 
or about 3 to 4 inches high, thin out to stand about 2 inches 
apart, keeping them well hoed and free from weeds at all 
times throughout the season.
