The encouragement given to the importation of the materials of manufacture by bounties, has been principally confined to such as were imported from our American plantations.
The first bounties of this kind were those granted about the beginning of the present century, upon the importation of naval stores from America. Under this denomination were comprehended timber fit for masts, yards, and bowsprits; hemp, tar, pitch, and turpentine. The bounty, however, of £1 the ton upon masting-timber, and that of £6 the ton upon hemp, were extended to such as should be imported into England from Scotland. Both these bounties continued, without any variation, at the same rate, till they were severally allowed to expire; that upon hemp on the 1st of January 1741, and that upon masting-timber at the end of the session of parliament immediately following the 24th June 1781.
The bounties upon the importation of tar, pitch, and turpentine, underwent, during their continuance, several alterations. Originally, that upon tar was £4 the ton; that upon pitch the same; and that upon turpentine £3 the ton. The bounty of £4 the ton upon tar was afterwards confined to such as had been prepared in a particular manner; that upon other good, clean, and merchantable tar was reduced to £2:4s. the ton. The bounty upon pitch was likewise reduced to £1, and that upon turpentine to £1:10s. the ton.
The second bounty upon the importation of any of the materials of manufacture, according to the order of time, was that granted by the 21st Geo. II. chap.30, upon the importation of indigo from the British plantations. When the plantation indigo was worth three-fourths of the price of the best French indigo, it was, by this act, entitled to a bounty of 6d. the pound. This bounty, which, like most others, was granted only for a limited time, was continued by several prolongations, but was reduced to 4d. the pound. It was allowed to expire with the end of the session of parliament which followed the 25th March 1781.
