Garden Raiders

Sir Evelyn Howell, who lives in Cambridge, recommends to me the use of black thread to protect peas from jackdaws much in the same way as it is used to keep sparrows away from fruit bushes, and I intend trying it not only over peas but over young cabbage plants. When. I visited the cabbage patch I 'was dismayed to see havoc that seemed to have been done by caterpillars. A second glance proved that birds had nibbled the leaves of the plants until only stalks remained, for other plants wader cloches had escaped. The crime has been committed by jackdaws. They are never out of the garden and pigeons visit infrequently at the moment. The jackdaws will go short of salad until the plants can be replaced and then they may be discouraged if the thread does what we hope it will do.
