. The Indiana weed book. Weeds. 20 THE INDTANA WEED BOOK. first a laborious one, but each year gradually lessens until in time it takes but a few hours, whereas at first it may have taken a week. A perennial with running rootstocks close to the surface can often be in great part eradicated by several shallow plowings and harrowings in summer, thus allowing the sun to reach and dry up the underground parts; or it may be killed by covering deeply with soil in early spring and so smothering out the perennial por- tion, that is, preventing it from forming leaves to store up future nourishment. Another method of dealing with perennial weeds is to crowd them out with clover, rye or some early and rapidly grow- ing crop. Many weeds are killed out more easily in this than any other way. General Rules foe Exterminating Weeds and Keeping the Farm Clean. 1. Sow clean seed.—Examine carefully all seeds purchased, especially those of clover and grasses, to see that they do not have weed seeds mixed with them. It is far better at any time to pay a high price for clean seed than a low price for seed that will stock the farm with weeds. If the farmer cannot buy clean seed he should raise it upon a tract of ground especially prepared and kept clean for the purpose. In the list which follows a Fig. 4. Linen tester. brief description of the seeds of each of the worst weeds is given. A linen tester, which costs about 40 cents, will enable one to recognize, after a little practice, 80 per cent, of the seeds of Indiana weeds. A pocket Coddington lens of one-half inch focus, costing about $, is still better and will enable one to see the finer points of all seeds. These lenses can be had of the Bausch & Lomb Optical Co., Ro- chester, N. Y. 2. Rotate the crops.—Too many farmers of Indiana keep on year after year '' raising more corn to feed more hogs to buy more land to raise more corn," etc. Not only this, but they raise corn on the same land, especially if it be bottom gr
