_Fourth: The Economics of the Enterprise._ (a) The market of the raw material--the study of the market in relation to grades, to cost, to transportation, to quantity in cost of purchases, to time of purchase; (b) manufactured product; selection of models in relation to their use and their art values; their cost of manufacture; relation to the selling price; the relation of cost to quantity and quality; (c) the relation of the rate of wages paid in the shop to rates paid in similar industries, to cost of production, to needs of the workers; (d) necessary margin of income over expenses for the up-keep of the plant, for its extension, for the maintenance of the sinking fund and possible contribution to the expense of the school; (e) the economic value of the school to the work of the shop. _Fifth: Art and Service._ The shop will not depend upon the pupils in the school for models, but will welcome models which come from the pupils as evidence that the shop experience is a stimulating one. But it will be recognized that the pupils will have little to offer on account of their inexperience and that there is a world of designers from whom to draw and the shop is eager to command the best models which are obtainable. There will be a Jury for the determination of models to be manufactured. This Jury will receive certain instruction on the subject of toys, and will be responsible for making further study of the subject. But as has been pointed out for the last ten years by Caroline Pratt, who has given the subject scientific attention, toys are the t of little children which, they use in their effort to become acquainted with their environment, which they use in schemes of play, and which are in fact efforts on their part to try out and experience the adult life into which they are thrown.
