can also be used. They love moist, clayey, or loamy 
soils. In gravelly or sterile soils in the northern 
part, Canada blue-grass outranks its better-known 
relative. 
ATLANTIC COAST 
From Maine to Maryland and Virginia blue-grass 
does not thrive near the coast. ‘The slight elevation, 
heavy rainfall, and moist clay soils do not seem adapted 
to its best development. Redtop and the bent grasses 
are here at their best. They supersede blue-grass in 
lower New England and at other points along the coast. 
Over part of this area the soil is normally somewhat 
acid, a condition apparently not harmful to species of 
Agrostis. At Washington, D.C., redtop is being used 
exclusively in new seeding on the Public Grounds. 
SOUTHERN STATES 
Bermuda grass is the standard lawn grass in most 
ofthis region. It has all the characters of a good lawn 
_ grass except that it is not resistant to frost. The first 
heavy frost of autumn changes it from a beautiful 
green to a light brown color, and thus it remains until 
late in the following spring. Scarifying the sward with 
the disk-harrow in the fall and sowing a winter grass, 
such as Italian rye-grass, has been recommended and 
has proved successful in some trials. St. Lucie grass, 
a variety of Bermuda, and St. Augustine grass, a 
coarser, creeping species of the Florida coast, are also 
used. Korean lawn-grass is similar to St. Augustine 
grass. All these are not frost resistant, or at best but 
little more so than Bermuda.
