The present publication continues the series of annual statistical reports by the Office of Education on land-grant colleges, which first began for the academic year 1869-70. Data on enrollment, earned degrees conferred, income, expenditures, endowment, and physical plant facilities of the 69 land-grant colleges and universities for the year ended June 30, 1955 are presented in this bulletin. This series is distinguished, first, by its long history of 86 years, and second, by the scope of information regarding the individual colleges and universities in the land-grant group. To a greater extent than previously, the Office of Education is coordinating its data collection from the land-grant colleges and universities with the program of data collection from all institutions of higher education. This procedure facilitates comparisons with other groups of institutions and makes the data more useful generally. Certain features of the present report deserve mention. First, there is provided a summary of the numerous laws (dating from 1862) under which Federal funds are allotted to the land-grant institutions. Second, the text has been expanded to call the reader's attention to various important figures of the tables. Third, two new tables have been included on degrees conferred by the land-grant institutions (tables 10 and 11). Finally, data have been systematically introduced to show the relative magnitude of the land-grant component in American higher education. Thus, the 69 land-grant institutions, constituting 5.1 percent of the 1,344 4-year institutions of 1954-55, included 20.3 percent of the total resident college-grade enrollment in 4-year institutions in November 1954, conferred 39.3 percent of all doctoral degrees granted in the year ending June 30, 1955, and were responsible for 54.2 percent of all expenditures for organized (separately budgeted) research in the fiscal year 1955. The summary of legislation presented in the Appendix was prepared in consultation with Lloyd E. Blauch, John Hesphey, Walworth Brown, and Luke M. Schruben. (Contains 30 tables and 10 footnotes.)
