Fruit is coming to occupy an increasingly important place in the diet. This statement is true not only for fresh fruit, but also for themany cooked products of which fruit forms an important part.More accurate information regarding the cooking properties of our various kinds of fruits is desirable from the viewpoint of both producer andconsumer.It is believed that the data presented in this paper on the Cooking Qualities of Certain Apple Varieties add to the general fund of information on this subject. The material upon which this article is basedwas presented as a thesis to the Faculty of the Oregon Agricultural Collegeas part fulfillment of the requirements for a Master's Degree in Home Economics by Harriet B. Gardner. A. B. Coaniay, Director.

Besides possessing a pleasing flavor and a small amount of food value, apples have a distinctly healthful influence upon the body, and should be used mole in the diet than they are now. In the hope of gaining definite knowledge of the cooking qualities of the more common varieties of apples grown in Oregon, a series of systematic experiments were carried out in the Oregon Agricultural College in 1913-14. Object In conducting the investigation three distinct objectswere kept in view. First, to determine the relative value ofa number of varieties of apples for certain cooking purposes, including sauce, pies, dumplings, jelly, andmarma- lade.It is hoped that the results obtained will aid the housewife in selecting varieties for her particular needs. Second, to determine some of the general principles underlying these cooking properties and to trace the relationship of cooking in generalto the dessert quality of the apple. Third, to ascertain if differences in the cooking quality are associated with differences in the gross morphology and cell structure of t.he fruit. Materials Used The materials used in the investigation consisted in fruit of medium grade of 71 varieties of apples, a large percentage of whichare standard commercial sorts.Most of this fruit was grown at Corvallis, Ore., thoughsome was obtained elsewhere.Following is a table giving the names of the varieties and t.he season when each is most likely to be at its prime. METHODS OF PROCEDURE The apples were first washed, then weighed.To insure uniformity in results, one pound ten ounces, as purchased, was the weight taken each time for sauce, marmalade, and jelly.The apples were then pared and weighed 7 TABLE I.SEASON WHEN VARIOUS APPLES ARE AT PRIME FOR COOKING.
