To this the writer would add the testimony of a lady who has used this work with several classes of young girls and young ladies. She remarked that she had never known a school-book that awakened more interest, and that some young girls would learn a lesson in this when they would study nothing else. She remarked, also, that when reciting the chapter on the construction of houses, they became greatly interested in inventing plans of their own, which gave an opportunity to the teacher to point out difficulties and defects. Had this part of domestic economy been taught in schools, our land would not be so defaced with awkward, misshapen, inconvenient, and, at the same time, needlessly expensive houses, as it now is. The copyright interest in these two works is held by a board of gentlemen appointed for the purpose, who, after paying a moderate compensation to the author for the time and labour spent in preparing these works, will employ all the remainder paid over by the publishers, to aid in educating and locating such female teachers as wish to be employed in those portions of our country, which are most destitute of schools. The contract with the publisher provides that the publisher shall guaranty the sales, and thus secure against losses from bad debts, for which he shall receive five _per cent._ He also shall charge twenty _per cent._ for commissions paid to retailers, and also the expenses for printing, paper, and binding, and make no other charges. The net profits thus determined shall be divided equally, the publisher taking one half, and paying the other half to the Board above mentioned.
