With respect to the labor of inmates of such of the institutions within its jurisdiction as are owned or managed and controlled by the Commonwealth or any political sub-division thereof, the committee shall, in addition to the powers and duties enumerated in the preceding section of this act, have the power and its duty shall be:—

(a) To maintain a manufacturing fund for the purposes specified in this section. The original manufacturing fund of the committee shall be the manufacturing fund paid to the committee by the Prison Board Commission, as provided in this act, together with any and all sums due and owing to such Commission, and the unexpended balance of any appropriation made for the use of such commission. To such fund there shall be added from time to time such amount or amounts as shall be appropriated by the General Assembly;

All receipts from the sale of the products, manufactured or produced by the labor of the inmates of any such institution, shall be credited to the manufacturing fund and used for the purchase of machinery, equipment, raw materials, and supplies, and for the payment of wages to such inmates;

(b) To sell to the Commonwealth or to any political sub-division thereof, or any institution, owned, managed, or controlled by the Commonwealth, or any political subdivision thereof, at not more than the prevailing market price the products of the labor of such inmates; Provided, That institutions within the jurisdiction of the Committee owned, or managed and controlled by the Commonwealth, or any political subdivision thereof, shall have the privilege of selling directly such of their agricultural products as they do not consume, but every such institution selling agricultural products shall account for and pay to such committee the proceeds of the sale of such products.

Any surplus of the products of the labor of such inmates which cannot be sold to the Commonwealth, etc., shall be sold in the open market, but any such product sold in the open market shall not be sold for less than the prevailing market price.

Should any institution desire to use the products of the labor of its inmates, other than agricultural products, it shall purchase the same from the Committee on Delinquency;

(c) From time to time to fix the compensation of such inmates for labor performed by them; Provided, That the rate of compensation to such inmates shall be based both upon the pecuniary value of the work performed and on the willingness, industry, and good conduct of the inmate performing the same;

(d) To make rules and regulations governing the payment of compensation earned by such inmates. Such rules and regulations may provide for the payment of a part of their compensation to inmates during their term of confinement to be used for such purchases as such rules and regulations shall permit. They shall also provide for the bi-monthly payment of such part of the compensation of such inmates as the committee shall determine to the dependents of such inmates, and for the payment of the unpaid balance of such compensation to such inmates at the time of their discharge, or at periodic intervals on and after their discharge; and,

(e) To establish rules and regulations for the keeping of records and accounts by all such institutions, showing the labor performed by the inmates thereof, the value of the products thereof, and the wages paid to inmates, or their dependents, or both.
