. Some common insects and insects of Nebraska corn fields and potato patches... However, one man who fails todestroy the thistles growing on his place can infest the entire neighborhoodbecause of the tumbling nature of the weed. BUFFALO-BUR(Genus-Solanum) The buffalo-bur is a native of the west but has gradually worked eastuntil it is found in all parts of Nebraska. It resembles the horse nettle, and, like it, is related to the potato. However, it differs in that it has veryspiny burs, in place of smooth berries, and has yellow flowers, also moreand stranger spines than are generally found on the horse ruettle. The bursbecome fastened to rabbits and other animals, by which means the blaok, irregular seeds are scattered far and wide. As the plants are somewhatbushy, they sometimes break loose at the surface of the ground and tumblelong distances, scattering their seeds as they go. As the buffalo-bur is an annual, it can be destroyed by cutting beforespeeding. The seeds are found in alfalfa and clover. The plants are seldomfound in fields that are thoroly cultivated..

Both are found alongroadsides, low ground and waste places, but the smaller ragweed is verycommon in cornfields. The greater ragweed grows from four to eight feethigh but the smaller species seldom attain a height to exceed four feet. Thestems of both kinds are very rough and the leaves divided. The flowers arepale green in color and curing a certain stage in their development willleave a red stain on the skin if pressed between the thumb and first finfeer.The brown, urn-shaped, beaked, tapering seeds are found in oats, wheat, barley, and other grains, from which they are especially hard to separate. Theseeds retain their vitality for many years. This weed may be eradicated bypulling, mowing, burning, or any other method that will either preventseeding or destroy all see
