By the Smith-Hughes Act of February 22, 1917, both teachers and supervisors, as well as training for teachers and supervisors in the fields of agriculture, home economics, industrial and trade subjects, were provided.[63] The Federal Board for Vocational Education consisted of the Secretaries of Agriculture, Commerce, and Labor, the United States Commissioner of Education, and three citizens appointed for terms of three years, at $5,000 a year. One of these three is to represent the agricultural interests, one the manufacturing interests, and one labor. The board was given power to make studies, among other subjects, of home management and domestic science. While instruction under the first of these Acts may be given by means of home demonstrations, it is limited under the second Act to such as can be given in schools and classes. This Act provides for co-operative effort between the Federal government and the states. The large sum of $200,000 for the support of the board, and considerable sums for certain minimum contingencies, were appropriated. Major appropriations were provided for, beginning with $500,000 for paying salaries for teachers and supervisors in agriculture, and increasing by $250,000 until the sum of $3,000,000 was reached, to be distributed in proportion to rural population among the states on condition that the states take appropriate action consenting to the Act and appropriating dollar for dollar (Section 2). A similar appropriation was provided for the teaching of trade, home economics, and industrial subjects, beginning with $500,000, increasing by $250,000 annually, until the amount of $3,000,000 was reached, this to be appropriated in proportion to the urban population in the various states. Certain minima were prescribed, and it was laid down that not more than 20 per cent of the amount allotted for salaries should go to teachers of home economics (Section 3). No part of the appropriation is to pay for buildings or for work done in private institutions (Section 11). In the same manner as in the earlier Act an initial appropriation of $500,000 was made toward meeting the cost of training teachers and supervisors in agricultural trade, home economics, and industrial subjects, these to increase by installments of $200,000 and then by $100,000, until $1,000,000 was reached, to be distributed among the states in proportion to population. Certain conditions were prescribed as to the action to be taken by the states, and the appropriation by the state of "dollar for dollar" toward the training of these persons was required.
