produce larger yields.

Early white potatoes, early cabbage, water melons, musk-melons,
tomatoes and other early truck and market garden crops are also grown
on light soil holding from five to seven per cent. of water. The main
crop of potatoes and cabbage and the canning crop of tomatoes are
grown on the loam soils holding from ten to eighteen per cent. of
water. Such soils produce a later though much larger yield.

Upland cotton produces best on a deep loam that is capable of
furnishing a uniform supply of about ten or twelve per cent. of water
during the growing season.

Sea Island Cotton grows best on a light, sandy soil holding only five
per cent. of water.

On light, sandy soils the Upland Cotton produces small plants with
small yield of lint, while on clay and bottom land, which are apt to
have large amounts of water, the plants grow very large and produce
fewer bolls, which are very late in maturing.

Corn, while it will grow on a wide range of soils, produces best on
loam or moist bottom lands holding about fifteen per cent. of water
during the growing season.

The grasses and small grains do best on cool, firm soils holding
eighteen to twenty-two per cent. of water.

Sorghum or "Molasses Cane" grows best on good corn soil, while the
sugar cane of the Gulf States requires a soil with twenty-five per
cent. of water for best growth.

While the amount of water which a soil will hold is determined largely
by texture, it is also considerably influenced by the amount and
frequency of rainfall and the location of the soil as to whether it be
upland or bottom land.

The average percentage of water held by a soil during the growing
season may be approximately determined in the following manner:

Sample the soil in one of the following methods:

Take to the field a spade, a box that will hold about half a bushel,
and a pint or quart glass jar with a tight cover. If a cultivated
field, select a place free from grass and weeds. Dig a hole one foot
deep and about eighteen inches square. Trim one side of the hole
square. Now from this side cut a slice about three inches thick and
one foot deep, quickly place this in the box and thoroughly break
lumps and mix together, then fill jar and cork tightly.

Another method is to take a common half-inch or two-inch carpenter's
auger and bore into the soil with it. Pull it out frequently and put
the soil which comes up with it into the jar until you have a sample
