The material is attractively arranged, presented in a breezy, readable form, tinged with the spirit of sentiment, calculated to excite and hold the interest of the girl reader. It cannot fail to make the careless, irresponsible girl more thoughtful to untangle many perplexities for the troubled girl and to arouse ambition for personal efficiency in all girls who read it. The emphasis for gaining success is laid almost entirely upon personal efficiency. While the necessity cannot be made too clear to the girl—who is inclined to look upon her wage-earning life less as a profession than the boy—the book is disappointing in its almost total lack of recognition of the many failures in industry to meet the reasonable claims of efficiency. The absence of such information is prone to tempt the girl into industry sooner than there is financial need for her service, and does not protect her incentive or optimism, which protection is hoped for by the concealment of these facts. It is this feature which is too often damaging to the beneficial effect of many vocational bulletins published without an intimate and accurate knowledge of the trades discussed. This setting forth of disadvantages as well as advantages has been most excellently done in another recent Boston publication, Survey of Occupations Open to the Girl of Fourteen to Sixteen Years, by Harriet Hazen Dodge. This pamphlet presents both sides of the question in a most helpful, concise and scientific form. The knowledge of the “disadvantages” is needful to the educator with whom will lie the decision as to the kind of trade or industry with which education can assist and co-operate in moulding the life of the child. Vocations for Girls will be of assistance to the elementary teacher in providing an opportunity for intelligent contact with the girl worker, and suggestive material for further investigation as to the educative motive in trades and the benefit of the “occupative motive” in the girl pupil. Little or no new information is given the sociological worker concerning specific lines of work for girls, or concerning her education for wage earning and home making. The note of unquestioned recognition of the permanency of the girl’s wage-earning life which pervades every page of the book, is most welcome and all too urgently needed—both by girl and employer. But above all else, let me repeat that the book deserves a pioneer place in vocational literature, as one of the outward proofs of that which has long been felt,—that the destiny of the wage-earning child can be safely trusted to the keen interest, stimulating sympathy and sound judgment of his or her main dependence—the most potent of our social forces—the public school teacher.
