 Al ansidious Disease.
 Many farmers who have attributed their meager harvests to bad weather, lack of. fertilizer or poor soil may dud, on examining the roots, that they are covered with swellings or 'gailsi of Varying sizes, caused, by the minute eelworms or nen1atodes that are. hecominsa@ SO connson in sandy soils. I: These little parasites are ire quentfy 9ihtreduced on plants ot figs, peaches. grapes! tutc., 'oI. on .son from infested fields and multiply rapidly On a greatfRafiety ,of, crops, Severely diseased plants either die 1oan are dis tinctly stpnted.

 The farmer may choose from the following list Of crops immune or resistant to root-knot those best suit ed to his needs:' Barley, begsa1- weed, Brabham oowpea. b,oon-colll miilet, corn. crab grass, Iron coWpea, peanut, pearl nillet, rye, sorghum,
 velvet bean, wheat and Niptei oats,
 The above are safe on infested land, but the following crops sus- ccptible to 1oct-knot must be ayoid- ed: Alfalfa, asparagus. beans, beets. cantaioupe, celery, clover, cotton, cowpeas tall except Iron and Blab- ham, cuctimbers, figs, Irish potatoes, mulberries, okra, peaches, soy beans, sugar cane, sweet potatoes, tobacco, tomatoes, Vetch and watermelon.
 ln addition to these plants, most common weeds are attacked by the nsmatodes, and, if TOT no other reas- on, should therefore be kept from the fields in which it is desired to eliminate eelwo1ms.
 Good Rotation.
 TNJ, gested for fields infested with root lTuoi in the tall soW winter rye and allow it to make a good growth be- fore blowing the land fer the next crop. Turn under the rye as green manure in early spring and plant corn, later placing one of the two resiglant varieties of cowpeas, Brab- ham or Iron, in the drill. between the VOWS. The second fall SOW winter grain, preferably oats, which may bel allowed to riper or cut for hay while green. Follow this with. Brabham or Iron cowpeas which can be soWn broadcast, or better in 2-foot drills where they can be cultivated. Har- vest the cowpeas as nay and asaln soW winter gram III the tall. Flow unae, in time to plant cotton the third year F it is desired to plant cotton every fourth instead of every third year, follow the last crop or wlnler grain with d resistant coWpea (lron or Brabham) broadcast or iii the drill and cut for hay. The fourth fall plant winter grain blow under in the spring, and then, plant cotton.
