ficult to secure satisfactory results unless 
the soil is open and warm. If necessary, 
under-drainage by means of tiling should 
be resorted to. This is a technical subject 
governed largely by local conditions, and 
anyone having work of this sort to do 
should make a special study of its engineer¬ 
ing phase with reference to the problem. 
Lawn soils not in the limestone regions 
are apt to be somewhat acid. This condi¬ 
tion should be corrected by an application 
of air slaked lime at the rate of thirty 
bushels to the acre. This is best applied as 
a winter dressing. 
Seed Mixtures 
To the average buyer the various trade 
mixtures of lawn seed on the market smack 
of the alchemy of the Middle Ages. There 
is something awe-inspiring in the elaborate 
number of varieties they combine into one 
package of seed and the relative efficacy 
claimed for each special combination. To 
clear the subject in your mind here is an 
analysis of what to use, and where: 
The map in Figure 2 graphically shows 
the regions to which the principal lawn 
grasses are adapted. There are three divi¬ 
sions. The first or Northern, shown by the 
unshaded portion on the map, embraces 
those States where Kentucky blue grass is 
the standard for practically all situations. 
The chief exceptions to its full use are in 
the Atlantic coast region where the moist 
clay soils are inclined to be acid. Here you 
will find redtop and the other bent grasses 
as the basis for lawns. 
In the extreme northern part of the 
United States, in some localities are found 
rather gravelly and sterile soils. Upon 
these the growth of Canada blue grass has 
been found to excel that of the Kentucky. 
In some arid portions of the Great Plains 
region the grasses which are native to the 
special localities grow better than others. 
The second or central division is shown 
by the cross-hatching on the map. In this 
group of States no distinct line'of demarca¬ 
tion between the grass areas exists. The 
blue grasses predominate in the northern 
part, but Bermuda grass supersedes them in 
the southern and warmer parts of the 
States. Those contemplating the building 
of lawns in this section should carefully 
study the varieties in common use in their 
particular locations and make use of the 
grass which is giving the best results. 
Grass in the South 
The third or southern division, shown by 
the shaded portion of the map, is the region 
where Bermuda grass is the standard for 
lawns. A few other varieties are used in 
special cases, but Bermuda grass has thus 
far exceeded all others for common use. 
The chief exception to the general use of 
Bermuda grass in this region is St. Augus¬ 
tine grass. This has proved to be better 
adapted to shady conditions than the other 
and is consequently becoming more popular 
for this particular use.

In Fig. 2 the country is divided according to the regions to which 
the principal lawn grasses are adapted. The unshaded portion con¬ 
sists of those States where Kentucky blue grass is the standard for 
virtually all situations. In the gray areas Kentucky blue predomi¬ 
nates in the north, and Bermuda grass in the south. The black 
sections are those for which Bermuda grass is the standard sort 
Additions to the map in Fig. 3, for a loam soil in sun, are: Rhode 
Island, 7 lbs. Kentucky blue, 7 lbs. redtop, 7 lbs. Rhode Island bent. 
7 lbs. white clover. Connecticut, Kentucky blue, R. I. bent, white 
clover. Massachusetts, 45% fancy Kentucky blue, 20% fancy red- 
top, 15% R. I. bent, 15% Italian rye grass, 5% white clover. Md..
