In the introductory chapter the problem of this study was set forth in terms of certain questions concerning objectives in dramatics in the high schools of Virginia. The subsequent chapters recorded a search for data which might yield acceptable answers to these questions. Thus, Chapters II and III related the manner in which a list of objectives has been formulated. Chapter IV recorded the development of an instrument for discovering whether the objectives listed were those toward which dramatics activities were being directed in a given group of schools. It also gave the statistical results obtained from its use in 61 Virginia high schools. The chapter is to present an interpretation and summary of these data. Logic would suggest that the interpretation of data begin with a consideration of the questions. / M.S.

Since this study is largely an analytical appraisal, its purpose is not to solve any specific problem of fluid milk marketing, but to bring into focus problems that warrant a detailed and objective analysis. The procedure followed was divided into two parts. The first phase involves a review of the literature related to the regulation and control of the production, distribution and pricing of milk. Secondly, a study of the Lynchburg, Virginia milk market was made to determine the problems that have been encountered in this particular market. In addition, some appraisal is made of the role the control program has played in the production, distribution and pricing of milk in this market. / M.S.

In this course of their work J. Risi and A. Labrie (1) found that guaiacol and vanillin were among the products derived from the sap of the sugar maple. By using a five percent sucrose solution and equal quantities of vanillin and guaiacol, a little calcium malate and manganese acetate, they obtained an amorphous powder possessing no odor of vanillin or guaiacol but having an odor greatly resembling the odor of the extracts of the sugar maple. This work is an investigation of the actual products of the reactions involved and the mechanism pertaining thereto. It is proposed to study this problem by carrying out the experiment of Risi and Labrie except that the constituents guaiacol, vanillin and sucrose will be used first one at a time, then two at a time and finally all together in an effort to determine the reaction and its mechanism. The following conclusions have been drawn from the work done: 1. The author has been unable to duplicate the work of Risi and Labrie by following their brief directions. 2. Several modifications of their procedure failed to produce the product described. 3. No change was found when each component was used alone in any of the modifications. 4. No change was found when the components were used two at a time in any of the modifications used. 5. No change was found using all three components in any of the modifications used. / M.S.

The object of this study is to determine the factors that influence the fleece value, the experimental procedure, necessary to discover these points, and the effect of culling sheep toward fleece improvement. The clean yield per fleece and the grade of wool were thought to be of equal importance in earning a greater return per fleece. In making such a comparison, wool samples were taken from twelve Hampshire ewes and twelve South-Down ewes, of which the wool represented Three-eighth Blood and Half-blood respectively. Concentrations were given to the fact that there might be some difference in the production of clean yield between young ewes and old ewes. The samples were subdivided into two age-groups within each breed of sheep. For convenience, these wool samples, taken from ewes ranging from yearling to four years old, were grouped into “Young Group”, and those samples taken from ewes over four years old were grouped into “Aged Group”. The work done will be reported in detail in later chapters. The most important factors that influence clean yield were staple length and grease fleece weight. When staple length or grease fleece weight increased the clean yield also increased due to: (1) the material increase from the increased staple-length and the increased grease fleece weight; (2) the decrease of shrinkage percentage, which is associated with the increase of staple length. Other factors ranged from moderate importance to non-importance in relation to clean yield. (a) Density of fiber was moderately important in relation to clean yield; (b) Body weight was slightly associated with clean yield; (c) Crimp was rather important in wool uniformity than in clean yield; (d) Fineness is extremely important in wool quality instead of clean yield. Fleeces from aged sheep over four years old were lighter in clean yield than fleeces from young sheep. Finer wool fleeces were much less in clean yield than coarse-wool fleeces. Farm return was in favor of coarser wool per fleece. Major emphasis should be placed on the average record of staple length and grease-fleece weight, less emphasis on body weight, and on crimp, in a culling program of all ewes. Intensive measurement should be done on all characters of wool of all rams. If two ewes produce equal amounts of grease fleece, and equal length of staple, the older one should be culled. / M.S.
