No Plough, No Spade The no-digging campaign advances; and now

the roller begins-to sup- plant the spade. The results of the Chertsey research experiments are awaited with wide interest. It must be remembered that the no-digging theory followed the American no-ploughing theory; and the originator of that revolution has now published a sort:of-revised" estimate of, his own.most successful practices: Ploughing in Prejudices, by 4. Faulkner (Michael Joseph, 8s. 6d.), with a blessing from Wye Agricultural College. It is all very interesting. If gardeners can spread over their soil in autumn a thin layer of well matured, almost friable compost,. roll it flat and ask the worms to help, their spring-sown seeds will do wonders. The trouble lies with the process. It is an oddity in my garden that some self-sown sweet peas have outflowered and long outlasted those sown in specially prepared ground.
