Il is usually necessary to rake in several directions to lift aIl of the stens and the grass should be, clipped imme- diately to prevent the -stems -reclining agairi below the level of the cutter bar of the mowcr. FoIlow Procedure Carefully It is not intendcd to convey the impression that the control. of crab grass by the methond of raking and clipping is a one year 'proposition or that it wiIl be effective unless done carefully. But, this method has been uscd effcctivcly for several years on ýgolf courses and lawns with the re- suit that the second year the' amount of crab grass present bas been great- y reduced and the third ycar it bas ceascd to be. a problem of more than slight importance. At the same ime lifting and clipping the hunners produccd by the grass eliminates. bhose portions. prlilcipàlly responsible for the smotbering of the lawn'grass and the usual, injury caused: by this grass is imniediately reduced. In fact, elip>ping. the seed stems at the time the spikes 'are setting, secds so de- 'italizes the crab grass that the.plants frequcntly die without, having donc rore than slight injury to the lawn. In a few locations crabgrass is now roducinii seed stems and these areas u lIp 1111 t air.
