PROTECT YOUR LAWN 
FROM DROUGHT DAMAGE 
WITH DRUMCLIFF EXCLUSIVE “'A-A’” PROGRAM 
HERE can be no doubt that serious drought conditions have damaged many lawns 
during the past few years throughout many eastern states. In some areas water 
supply was so limited that householders were forbidden to sprinkle lawns and gardens 
with city water except during limited hours. 
One of the most practical plans for meeting this 
condition is (1) to improve the soil condition so 
that whatever water is available is retained longer 
in the soil (2) encourage turf to make deeper 
roots (3) create a more friable soil condition to 
lessen the “run off” of water which so frequently 
occurs when heavy showers fall on dense, com- 
pact, soil. 
MECHANICAL AERATION 
Soil that is largely clay becomes compact as a 
result of the spring rains, then bakes hard in the 
heat of early summer. This causes grass roots to 
remain close to the surface in the upper soil strata 
which dries out most rapidly. The first step rec- 
ommended is to break this heavy crust with a 
mechanical aerating device. The Aeri-Fork for 
small lawns or the Spike Disc Cultivator for larger 
areas. 
Aerating in this way, two or three times between 
April and November, will often cause marked im- 
provement. Aeration has been widely practiced on 
golf courses, parks, cemeteries, and other large 
lawn areas since practical motor-driven equipment 
for the purpose has been developed. Now smaller 
units for use by home-owners are available and 
DRUMCLIFF is prepared to supply you. 
This mechanical opening of the soil admits more 
air and water and also makes it possible to pene- 
trate the soil with Actumus to supply the humus 
needed to increase the power of the soil to hold 
and retain available moisture. On sandy soil or 
friable, loamy soil the aeration may not be needed 
but the application of Actumus improves any soil. 
ACTUMUS is entirely natural, and organic— 
true humus in stable and concentrated form. It 
does not burn or injure plants, roots, or soil or- 
ganisms. It is most effective in solution with wa- 
ter and easily applied with the Redi-Mix or GRO- 
GUN. These inexpensive devices are attached to 
the garden hose and spray the Actumus solution 
onto the ground quickly and easily. 
MAKES CLAY SOIL MORE CRUMBLY 
The application of Actumus to the soil has many 
beneficial effects. It causes clay soil to become 
more crumbly or friable. This is NOT a chemical 
action; it is the natural way, humus being the 
natural soil conditioner which makes the prairies 
and forests of the world such vast reservoirs of 
soil moisture. Actumus increases the water-carry- 
ing capacity of both clay and sandy soils; en- 
courages earthworms which tunnel, aerate and 
enrich the soil; developes the beneficial bacteria 
whose actions cause the soil particles to release 
natural fertility elements of the soil and make 
them available to the plant roots. 
Actumus penetrates and clings to the soil par- 
ticles and starts a chain reaction of beneficial ef- 
fects. It is recommended for improving an unsat- 
isfactory soil condition and for maintaining a high 
rate of fertility in good soil. It is effective alone 
or may be used in conjunction with pulverized 
lime-stone and other natural rock products (if 
needed) or with organic plant foods, compost, etc. 
Application may be made at any time except 
when the ground is frozen. Actumus will not de- 
teriorate either dry or in solution no matter how 
long it may be stored. It will not burn the grass 
or injure the soil or plants no matter how often 
or in what concentration it is applied. 
TEST THE “A-A” PROGRAM NOW 
Actumus is used by thousands of home-owners, 
gardeners and others in every state in a wide va- 
riety of soil and climatic conditions. Its use is 
especially indicated for lawns because it makes it 
possible to introduce much-needed humus in stable 
form into the soil WITHOUT DESTROYING EX- 
ISTING TURF. Vegetables, flowers, shrubs, fruit 
and berries respond equally to the soil improve- 
ment which Actumus brings about. 
HOW TO ESTIMATE YOUR NEEDS 
Because Actumus is not a “shot in the arm” 
plant growth stimulant, the results are long-lasting 
and cumulative. It will improve poor soil; it will 
maintain the quality of a good soil. As the soil 
condition improves, stronger rooting will bring the 
result of healthy turf with good color and top- 
growth. 
Ideal application of Actumus to lawns for the 
first time is one pound to each 450 square feet. A 
minimum initial application would be one pound 
to 900 sq. ft. The full application may be made as 
one sprinkling or as several milder applications 
at intervals of two to three weeks. Apply as a 
solution wtih one of the handy units mentioned. 
Rain or sprinkling will carry the Actumus along 
root channels to the lower soil levels. 
If you wish to test Actumus before giving your 
lawn complete coverage we suggest you mark off 
a definite area where nothing but the DRUM- 
CLIFF “A-A” program is followed. Aerate (if 
needed) with either the Spike Disc Cultivator or 
the Aeri-Fork. Then spray with Actumus solution, 
and water well to get the Actumus into the root 
zones as quickly as possible. Mow to 1% or 2 
inch height when needed. Observe the results 
compared with other portions of your lawn, espe- 
cially during and following any periods when rain- 
fall is deficient. Form your final opinion the fol- 
lowing spring after the lawn has established its 
new growth. 
EITHER IS EFFECTIVE: 
USING BOTH IS BEST 
The use of aeration or the use of Actumus will 
do much to improve a poor soil condition that is 
retarding the proper growth of a lawn. Using 
BOTH methods, however, is the best and fastest 
plan to achieve maximum drought protection and 
lawn improvement. These procedures, started now 
and continued during the summer months will also 
create an improved soil condition which will make 
subsequent re-seeding of the lawn more effective.

MECHANICAL AERATION 
SPIKE-DISC LAWN CULTIVATOR 
Especially Designed for Home Lawns 
BN This ‘‘push-model’’ aerator will cover 
a large area of lawn. The spikes cut 
small triangular pockets into the 
lawn that allow air, moisture and 
Actumus to settle into the soil. This 
unit has eight spiking discs of high 
carbon alloy steel; cultivates a swath 
16 inches wide. All metal 
handle shifts to push or pull 
position. Tray can be filled 
with stones or sand to pro- 
vide additional weight for 
deeper penetration of hard 
packed soil. The spike-disc 
is especially suitable for preparing an old lawn for reseed- 
ing. Opens and pulverizes bare areas to a greater depth 
than is possible with raking.
