to see that a low-priced mixture, with a large percentage of chaff, 
is not a good purchase. 
A lawn may be seeded down either in the spring or fall. If 
made in the spring, the work should be done as soon as possible 
after the soil is in a friable condition. From the latter part of 
March until the middle of May conditions are usually suitable. 
When the lawn is made in the fall, weather conditions largely de- 
termine the time of seeding. The seed may be sown at any time 
from the latter part of August until the beginning of October, 
but not during a period of drought unless there are ample facili- 
ties for watering artificially. 
As soon as the grass is between two and three inches high it 
should be mown. The lawn mower should be sharp and the 
blades set as high as possible. If the ground is soft or sandy it 
is a good plan to roll the grass lightly a day or two before mow- 
ing. This will compact the soil around the grass roots and pre- 
vent the grass from being pulled up when the mower is used.
