Cropping Programs 
The Chase P.M.G. is not a “‘stunt gadget’’ to use for a short 
while in early Spring. It is a practical horticultural tool, 
which can and should be used somewhere in the garden 
throughout the whole of the 12 months. 
Most important of all, Chase P.M.Gs. are made of glass, 
the only substance suitable for the protection of plants, for 
it lets in the heat and light rays essential for growth and it 
also prevents the warm air from getting out. These qualities 
are peculiar to glass, and glass substitutes simply will not 
do, for they starve the plants‘of light and lead to yellowing 
and stunted growth. 
Please do not confuse the Chase P.M.G. with the old 
outmoded ‘‘Hotcap’’ for although it will do all that the 
hotcap can and better, it is as different in its design, in its 
use, and in the result obtained as is possible. The Chase 
P.M.G. has a definite part to play in your gardening, be it 
January or June, April or October. To give you some idea 
of what we mean, here are four sample 12 months cropping 
programs. Once you have some P.M.Gs. in your garden, 
many more combinations will immediately be apparent, but 
the samples will give you an idea how versatile the P.M.G. 1s. 
. P.M.Gs. ON A SINGLE STRIP | 
Suppose you have only a very small strip of ground and 
cannot keep moving the P.M.Gs. about from place to place. 
What is the minimum area on which they can be used and 
what is the maximum crop that can be obtained ° 
First, the minimum area. A set of 10 P.M.Gs. needs an 
area 15 feet long and 2 feet wide—30 square feet in all. If 
you are to get maximum crops you must prepare the ground 
well. The top six inches ought to be about half compost, 
‘so your compost requirements will be about a quarter of a 
cubic yard, say 2 to 3 cwt. 
Now for the crops. 
Cover the ground with the P.M.Gs, at the pea of 
February to warm it and as soon as you can, sow two rows 
of lettuce 6 inches apart with a row of radish between the 
two lettuce rows. Now sow two rows of carrots, each 3 
inches outside the lettuces, Thin out your lettuces to stand
