5. This bill will injuriously interfere with existing colleges in the different States, in many of which agriculture is taught as a science and in all of which it ought to be so taught. These institutions of learning have grown up with the growth of the country, under the fostering care of the States and the munificence of individuals, to meet the advancing demands for education. They have proved great blessings to the people. Many, indeed most, of them are poor and sustain themselves with difficulty. What the effect will be on these institutions of creating an indefinite number of rival colleges sustained by the endowment of the Federal Government it is not difficult to determine. Under this bill it is provided that scientific and classical studies shall not be excluded from them. Indeed, it would be almost impossible to sustain them without such a provision, for no father would incur the expense of sending a son to one of these institutions for the sole purpose of making him a scientific farmer or mechanic. The bill itself negatives this idea, and declares that their object is "to promote the liberal and practical education of the industrial classes in the several pursuits and professions of life." This certainly ought to be the case. In this view of the subject it would be far better, if such an appropriation of land must be made to institutions of learning in the several States, to apply it directly to the establishment of professorships of agriculture and the mechanic arts in existing colleges, without the intervention of the State legislatures. It would be difficult to foresee how these legislatures will manage this fund. Each Representative in Congress for whose district the proportion of 20,000 acres has been granted will probably insist that the proceeds shall be expended within its limits. There will undoubtedly be a struggle between different localities in each State concerning the division of the gift, which may end in disappointing the hopes of the true friends of agriculture. For this state of things we are without remedy. Not so in regard to State colleges. We might grant land to these corporations to establish agricultural and mechanical professorships, and should they fail to comply with the conditions on which they accepted the grant we might enforce specific performance of these before the ordinary courts of justice. 6. But does Congress possess the power under the Constitution to make a donation of public lands to the different States of the Union to provide colleges for the purpose of educating their own people?
