Uniform binding, attractively boxed. $5.00 per set; carriage extra. Each volume also sold separately._ In this set are included three of Professor Bailey's most popular books as well as a hitherto unpublished one,--"The Country-Life Movement." The long and persistent demand for a uniform edition of these little classics is answered with the publication of this attractive series. THE COUNTRY LIFE MOVEMENT _Cloth, 12mo, 220 pages, $1.25 postage extra_ This hitherto unpublished volume deals with the present movement for the redirection of rural civilization, discussing the real country-life problem as distinguished from the city problem, known as the back-to-the-land movement. THE OUTLOOK TO NATURE (New and Revised Edition) _Cloth, 12mo, 195 pages, $1.25 postage extra_ In this alive and bracing book, full of suggestions and encouragement, Professor Bailey argues the importance of contact with nature, a sympathetic attitude toward which "means greater efficiency, hopefulness, and repose." THE STATE AND THE FARMER (New Edition) _Cloth, 12mo, $1.25 postage extra_ It is the relation of the farmer to the government that Professor Bailey here discusses in its varying aspects. He deals specifically with the change in agricultural methods, in the shifting of the geographical centers of farming in the United States, and in the growth of agricultural institutions.
