Keystone City Lawn 
Here is the ideal mixture for the city lawn 
builder—especially prepared for use where 
adverse soil and climatic conditions prevail, 
due to a combination of acid soils, coal smoke 
and hot summers. It has as its base a selec- 
tion of the most suitable permanent lawn 
grasses. These are combined with sturdy, 
quick growing grasses which act as a nurse 
crop and gradually disappear as the per- 
manent grasses become established. 
Keystone Shady Lawn 
A good combination of the best permanent 
grasses plus a mixture of hardy grasses 
more particularly adapted to shade. 
Mound City Lawn 
A blend of good, quick growing grasses 
for use where an immediate turf is wanted 
in soil of poor to medium fertility. It makes 
a good, seasonal lawn even if sown late in 
the spring.
