1. All money, securities and other property, real and personal, heretofore received by either of the state boards or hereafter received by the commission by way of gift, bequest or devise, may be retained by the commission and, except in so far as the purpose or manner of using the same is otherwise specifically designated or restricted by the terms of any such gift, bequest or devise, may be used in the commission’s discretion in either state for any park purpose; and the commission may likewise retain and use all revenue and income arising solely from such money, securities and other property so received by way of gift, bequest or devise or from facilities or operations financed solely by funds so received. In the case of revenue and income arising partly from specific property received by way of gift, bequest or devise or from specific facilities or operations financed partly by funds so received, the commission may likewise retain and use such proportion of such revenue and income as the amount of gifts, bequests or devises, or the proceeds thereof, invested in each such property, facility or operation, bears to the total amount invested therein. The legislature of either state may from time to time by law specifically made applicable to the commission prescribe other terms and conditions upon which or purposes for which any gifts, bequests or devises thereafter made of money, securities or other property may be accepted for use in such state or used in such state or prescribe a different manner of administering gifts, bequests or devises thereafter made in such state and the disposition of all revenues or income arising therefrom.

2. Either state may from time to time by law require the commission to render to any designated official or official body of such state such reports and such estimates of revenues and expenditures as may be specified in such law.
