method, being considered. Interesting charts show the shifting of centers of wool production in the United States from 1840 to 1900, and the complementary and the competing character of some of the common farm crops in their demands for the time of the farmer. Suggested chapter headings for a course in agricultural economics are given. 17. Physiological Effect on Growth and Reproduction of Rations Balanced from Restricted Sources. (Hart, Steenbock, McCollum, and Humphrey) This bulletin presents the results of four years of experimentation on the value of chemically balanced rations for cattle derived from single plant sources-wheat, oats, corn, and a mixture of all three. Heifers were fed rations from these restricted sources, but which were balanced to satisfy the requirements of the present theory of rutrition, i. e., adequate digestible nutrients and adequate available energy. The heifers fed the ration from the wheat plant produced weak, undersized calves, and showed a low milk production, while those receiving rations from the corn plant produced large vigorous calves and maintained a high power of milk secretion. The oat ration gave results inferior to the corn ration but superior to the wheat ration, and the mixture, results which were nearer those obtained with wheat. The investigations, which are being continued, have not so far shown to what factor the superiority of the corn ration over the wheat ration is due. An important fact is that the mixed ration from all three plants proved inferior to both the corn and the oat rations. It proved to be impossible to change a corn-fed animal to the exclusive wheat ration, without death, but a wheat fed animal improved markedly on the corn ration. The data show that there is a decided physiological value of various feeds, and that the feeding value cannot be expressed in terms merely of digestible nutrients and of energy value. 18. A Sclerotium Disease of Blue Joint and Other Grasscs. (Stout) During the past five years the fungus, Sclerotium rhizodes, has been found upon various grasses, especially blue joint. That this fungus may assume considerable economic importance is shown by the fact that in 1911 it destroyed or dwarfed 47 per cent of the blue joint plants on one marsh meadow near Madison. Among the grasses infected to a lesser degree are Kentucky Blue Grass, Timothy, and Wild Barley. The fungus was found in the roots, leaves, stems, and buds of the same plants, and was perennial in the soil and in the underground parts of the infected plants. The fungus appeared to spread only through infection of the underground parts of the plants. So far no means has been found of controlling the fungus. CIRCULARS OF INFORMATION 17. Draft Horse Judging. (Alexander) A condensed illustrated manual of the art of judging draft horses. Some of the subjects considered are the purpose and the use of the score card, the score card for draft horses, instructions for scoring, and common unsoundnesses to be noted. 18. The Curing and Testing of Seed Corn. (Moore) The importance of selecting seed corn in the field, properly curing it, and then testing each ear before planting. is emphasized. Methods are fully described for properly curing small lots of seed, and plans are given of a building for curing large lots. A simple seed corn tester is described. 19. The Control of Quack Grass and Canada Thistles. (Stone) On many farmis, 25 per cent of the crop-producing capacity has been destroyed by weeds. 'The two weeds considered are those which are preeminently troublesome such farms. Descriptions of the plants and their habits are given together with methods of eradicating them on both large and small areas. on 20. The Control of Moisture in Cheese. (Sammis, Laabs, and Suzuki) This circular presents the practical results of the investigations reported in Research Bulletin No. 7. The effects upon the moisture content of cheese curds, which result from varying proportions of fat or water in milk, and from different temperatures, sizes of curd knives, proportions of rennet, degrees of acidity, and pressure, are discussed. 21. Distribution of Licensed Stallions in Counties of Wisconsin. (Alexander) This circular shows the improvement in the horse-breeding industry of the state brought about by the Wisconsin Stallion Law. A list of the stud books recognized by the U. S. Department of Agriculture, and a list of those not so recognized, are given, also the laws pertaining to horse breeding in Wisconsin. The circular contains a complete directory of owners of all licensed stallions in the state, with the name and breed of the stallion. 22. Chemical Analyses of Licensed Commercial Feeding Stuffs. (Woll) In this circular is presented the annual report of the inspections made under the State Feeding Stuffs Law. A list is presented of the 229 manufacturers or dealers who took out licenses for the sale of 943 different brands of feed, and the guaranteed and the actual composition of 873 samples of feeding stuffs analyzed during the year is given, together with a discussion of the various feeds. 23. A Catechism on Bovine Tuberculosis. (Russell and Hastings) By questions and answers this circular fully explains the cause, effect, and mode of distribution of bovine tuberculosis. The tuberculin test, the only means with which the disease can be detected in all stages, is likewise described, directions are given for applying the test and interpreting the results, and the methods of controlling tuberculosis in cattle are also discussed. 24. Commercial Feeding Stuffs and Fertilizers for Sale in Wisconsin, 1911. (Woll) A list of the manufacturers of concentrated commercial feeding stuffs and of commercial fertilizers, who took out licenses in accordance with the State Feeding Stuff's Law is here given, together with the names of the various brands of feed licensed. 25. Analyses of Licensed Commercial Fertilizers, 1911. (Woll) This circnlar gives a list of the commercial fertilizers licensed for sale in this state, with the names of the manufacturers and the guarantees for valuable fertilizer ingredients. The results of the analyses of these and other brands of fertilizers are also shown. 26. Standard and Undesirable Types of Potatoes. (Milward) This circular, a large chart, shows the standard and also the undesirable types of Burbank, Early Rose, and Rural New Yorker potatoes, and emphasizes the advantages of establishing community potato growing centers in which only one standard variety of potatoes would be grown. A supplement shows the standard types of⚫ the Green Mountain, Peerless, Early Ohio, Irish Cobbler and Triumph potatoes.
