The trend in this direction can be seen in many ways. The growing prevalence of camping has increased the demand for articles of food ready for use, and even tea, coffee, and soups are delivered hot for the benefit of pleasure seekers.[304] The development of Western resources by Eastern capitalists has also increased the demand for such articles, and at least one housekeeper among the Black Hills of South Dakota, one hundred miles from a railroad station, speaks casually of doing her marketing in Chicago, and a housekeeper in North Carolina gives frequent and elaborate lunches through caterers in Philadelphia. The tendency even among persons of moderate means is more and more towards the employment of caterers for special afternoon and evening entertainments, although in villages and small towns this course as yet involves the employment of persons from large cities. The practice is not uncommon for the women connected with church organizations to hold every Saturday afternoon sales for the benefit of the society, of all articles of food that can be prepared the previous day for Sunday dinners and teas.[305] The most important medium for the sale of such commodities is the Woman’s Exchange.[306] It has already become an economic factor of some little importance, and it will become of still greater importance when it is taken out of the domain of charity and sentiment and becomes self-supporting on a business basis. One of its most valuable results is that it has set a high standard for work and has insisted that this standard be reached by every consignor, not only once or generally, but invariably. It has maintained this standard in the face of hostile criticism and the feeling that a charitable organization ought to accept poor work if those presenting it are in need of money. It has shown that success in work cannot be attained by a simple desire for it or need of it pecuniarily. It has taught that accuracy, scientific knowledge, artistic training, habits of observation, good judgment, courage, and perseverance are better staffs in reaching success than reliance upon haphazard methods and the compliments of flattering friends. It has raised the standard of decorative and artistic needle work by incorporating into its rules a refusal to accept calico patchwork, wax, leather, hair, feather, rice, splatter, splinter, and cardboard work. It has taught many women that a model recipe for cake is not “A few eggs, a little milk, a lump of butter, a pinch of salt, sweetening to taste, flour enough to thicken; give a good beating and bake according to judgment.”
