"The open fire has its place as a method of heating single rooms or small houses or as an adjunct to other heating systems. Even when not actually needed, it adds much to the enjoyment of home life, if the fireplace is properly built. Comparatively few understand the principles involved in the construction of chimneys and fireplaces, and even experienced builders make mistakes which not only affect the efficiency of the heating unit but frequently create a menace to life and property. This bulletin is designed to give the householder and prospective builder, and especially the farmer or other rural resident who builds or superintends the building of his own home, a working knowledge of the principles to be observed in planning and building chimneys and fireplaces, which if the are observed will go a long way to promote the comfort of the home and insure the safety of the property."--Page ii.
The bean crop of the Southwest suffers severe injury from the bean ladybird, which sometimes ruins entire crops. It is restricted to beans for food and attacks all kinds. Both beetles and their larvæ devour all parts of the plant -- leaves, flowers and pods -- but the chief injury is to the foliage. The pest can be controlled in small areas by hand-picking the overwintered beetles and by brushing the larvæ or young from the plants during hot, dry weather. On a larger scale it may be controlled by spraying with arsenite of zinc, arsenate of lead, or arsenate of lime. Clean cultivation should be practiced and early and late planting."--[2]
