What three Weeds can do.

Three weeds of moderate size and growth will occupy, says the "Prairie Farmer," as much ground, draw as much nutriment from it, take m as much of the life giving sunlight and of the food bearing atmosphere as a good stalk of corn. It must be a very rich "soil that can stand the full draft of two crops growing on it at the same time, one of corn and one'of weeds, and yet stint neither of them. The rays of sun so necessary to the life and growth of nearly all vegetation, of all crops, come to the planet m direct lines, and if interrupted by the stalks or leaves of weeds, cannot go around them to reach' the corn. The carbonic acid of the air is the great supplier of the main portion of all crops, both stalks, ■ leaves, and roots ; but this carbonic acid exists m very small quantities m the air, only about one quart of it m 2500 quarts of air, Air must be moving quite rapidj to bring m enough of this gaseous carbonic acid to supply the wants of a rapid growing cornstalk. A whole gallon, of the carbonic acid weighs only 113 small grains, of which it takes 7000 to. weigh a pound. Now, if weed leaves stand along with or near corn leaves, they steal away a good deal of this carbonic acid that the corn leaves want, and it is only when the wind is blowing strongly that enough comes to m,eet the wants of both cornstalks and weeds. The practical lesson of this is that every weed growing with or near the corn is robbing it of the very things ib wants from the soil and from the air, and is also stealing some of its needed .sunlight. Sixty to seventy cornstalks yield on an average about a bushel of corn. Two hundred weeds on the same ground use all the materials that' are needed by cornsbalks, enough to produce a bushel of corn. He must be- a poor, slow worker indeed, who cannot with a hoe cut and kill 2000 weeds m a day if "lie takes them when small. The evident lesson from this is that after we have used the horse implements to kill out what weeds we can without going down to disturb the young roots of corn, it would pay grandly to have men go over the ground with hoes and remove the • last weeds which are left. If one man kills 2000 weeds m a day,. he has destroyed a sufficient number of; thieves to steal from the'so'il, the air, and the sunlight, which would support stalks enough to yield ten bushels of corn, worth 12s or 16s. If the weeds are not large enough and growing thickly enough to rob the com of all its needed earth, air, and sunlight, yet every weed that does grow is doing something to diminish the health, vigour, growth, and ultimate yield of porn.
