I hose who want bright, thick, velvety lawns; or golf courses and putting 
greens which will stand the hard usage — all who have difficult grass-growing 
problems to solve have long realized that the most desirable invigorator 
would be a proper combination of 
LIIVIE 
for lightening clay soil and sweetening 
sour ones — for increasing the vigor 
and brightness of the grass while de¬ 
creasing the growth of weeds. 
and HUMUS 
for enabling clay soils to absorb and 
hold moisture and warmth; for over¬ 
coming the lack of moisture of light, 
sandy soils and tendency of such lawns 
to burn out quickly. 
the right combination of these ideal grass invigorators has never seemed 
possible, until the recent discovery at Pope’s Creek, Maryland, of a wonderful 
deposit of naturally combined 
“ CALCIUM-HUMUS ” 
as we have called this natural grass invigorator. Analyses by the most dis¬ 
interested authorities indicate that nature has done here—probably over a 
period of thousands of years—what man has unsuccessfully attempted again 
and again. 
HUMUS —that first essential to plant life; and CALCIUM are combined 
here in their most efficient proportions. On this property was grass of remark¬ 
able luxuriance and beauty — similar to the Kentucky blue grass — while for 
miles around there were no lawns of this highly satisfactory character. It was 
this fact that first indicated the treasure under ground—the rare, natural com¬ 
bination of “CALCIUM-HUMUS.” 
Throughout the East and wherever soils are deficient in limestone; along 
the Coast and wherever light sandy soils predominate; in the clay districts 
and wherever friability and warmth of soil is lacking, “CALCIUM- 
HUMUS” is first aid to the lover of fine lawns, flower beds, etc. 
It costs only half as much as the average lawn dressing — requires only a ton 
to the acre for good results on the average lawn—is odorless and easy to apply, 
and of lasting benefit to all vegetation; but particularly grasses. 
“CALCIUM-HUMUS” is not “just another fertilizer’’ — rather a soil 
stimulant which makes active and effective those elements of plant life found 
in every soil.

mower as often as the grass shows irregu¬ 
larities and becomes too thick. In the dry 
summer weather raise the cutting knives 
of the lawn mower to avoid cutting too 
close and drying the roots. Do not cut 
after fall is well established, as the grass 
should leave its own winter protection, but 
let this not be too long. Lawn mowers 
have been improved and they now come 
with ball bearings and large, efficient cut¬ 
ting edges. Most kinds may be equipped 
with a device for catching grass clippings 
and keeping the lawn in trim condition. 
If you would know what sort of grass 
to use for different conditions, you can do 
no better than consult a reliable seeds¬ 
man, whose lawn mixtures he will guar¬ 
antee as he does his reputation. But the 
following description of grass plants, com¬ 
piled by Mr. Luke J. Doogue, will be of 
help: 
Kentucky Blue Grass — Poa pratensis. Fine 
for lawns; grows slowly but vigorously almost 
everywhere but on an acid soil. 
Red Top — Agrostis vulgaris. Shows results 
more quickly than Blue Grass; will thrive on a 
sandy soil; fine in combination with Blue Grass. 
English Rye Grass — Lolium perenne. Grows 
quickly and shows almost immediate results; 
good to combine with the slow-growing Blue 
Grass. 
Various-leaved Fescue — Festuca heterophylla. 
Good for shady and moist places. 
Rhode Island Bent— Agrostis canina. Has a 
creeping habit; good for putting-greens, sandy 
soils. 
Creeping Bent — Agrostis stolonifera. Creep¬ 
ing habit; good for sandy places and to bind 
banks or sloping places. Combined with Rhode 
Island Bent for putting-greens. 
Crested Dog’s-tail — Cynosurus cristatus. Forms 
a low and compact sward; good for slopes and 
shady places. 
Wood Meadow Grass— Poa neinoralis. Good 
for shady places; is very hardy. 
Red Fescue— Festuca rubra. Thrives on poor 
soils and gravelly banks. 
White Clover— Trifolium repens. Good for 
slopes; not to be recommended for a lawn. 
Sheep Fescue — Festuca ovina. Good for light, 
dry soils. 
To introduce the ready-made lawn, use 
a combination of Kentucky Blue, Red 
Top and English Rye. The Blue Grass is 
slow, but the Rye and Red Top produce 
speedier results. The first month will see 
the newly seeded space a carpet of green. 
In time the Rye passes, the Red Top con¬ 
tinues to cover, while the Blue Grass 
grows sturdier each day until it crowds 
everything out by virtue of its own 
strength. Use 12 pounds of Kentucky 
Blue Grass, 5 pounds of Red Top and 3 
pounds of English Rye Grass to the 
bushel, and sow 3E2 to 4 bushels to the 
acre. 
For shady places Kentucky Blue Grass, 
Wood Meadow Grass, various leaved 
Fescue, and crested Dog’s-tail. Use 35 
per cent of the first two and 15 per cent 
of the last two. 
For conditions that require a quick¬ 
growing grass, and something that will 
bind and make a holding upon slopes un¬ 
der difficult conditions, the following is 
recommended; Kentucky Blue Grass, 30 
per cent; R. I. Bent, 30 per cent; Creep¬ 
ing Bent, 25 per cent; Sheep Fescue, 10
