Abstract
THE Royal Society for the Protection of Birds has just added to its attractive series of coloured ibod-charts of birds, pictorial representations of the pro portions of useful, harmful and neutral work (so far as human interests are concerned) done by the jack daw, kestrel, nightjar and yellow-hammer. The cards, which are issued at 4d. each post free, or 4s. 4d. for the series of 16, are telling exhibits for use in museums or school-rooms. Recently the Ministry of Agriculture and Fisheries has issued Advisory Leaflets describing the characteristics and habits of the barn owl, wood peckers, starling, swallow, martins and swift, lap wing and wagtails. A leaflet in the same series describes some simple nest boxes for the encourage ment of the breeding of useful birds in gardens, orchards and allotments. They cost Id. net each.
