It was during the ownership of Daniel Moore in 1770 that an Act was passed empowering him to bring, by means of a tunnel through the mountain range and an aqueduct, the water of the Wag Water (the Agua Alta of the Spaniards) to his estate, which means now serve in part to supply the town of Kingston with water. It was entitled “An Act to enable Daniel Moore, Esquire, to take up a sufficient quantity of water for turning mills for grinding sugar-canes, out of or from Agua Alta River, commonly called Wag Water River, in the parish of St. Andrew; and to convey the same to his works on the plantation in the said parish, called Constant Spring.” In 1898 the original brick-lined tunnel, which is about half a mile in extent, was straightened in parts, and converted into a concrete pipe of six feet diameter. The proposal to supply Kingston with water from the Wag Water was first made, it is interesting to note, as early as 1798. In 1811 there were on the estate 401 slaves and 22 head of stock. As the result of legal proceedings of a protracted character the estate about 1832 became the property of Mrs. Jasper Farmer Cargill (_née_ Jane Marston), when there were 312 slaves and 31 head of stock; the only estate in the lowland district of St. Andrew with more slaves being Hope. It later passed into the hands of Chrystie and Porteous, merchants of Kingston, the memory of this ownership still living in the title Porteous’s Pen, applied to a lower and now distinct part of the property. In the ‘seventies it was owned by a Captain Carson, a son of a member of the above-named firm. In the year 1888 the American Hotels company was formed in Jamaica, principally with Jamaica capital, and properties were acquired and two or three hotels were started, Constant Spring amongst the number. When the Jamaica Exhibition of 1891 was in preparation, the Government, thinking there was not enough hotel accommodation, passed the Hotels Companies law, and the directors of the Constant Spring hotel, as it was not paying as well as was anticipated, mortgaged it to the Government, to whom they subsequently handed it over. Golf links and tennis courts now usurp the place of cane-fields. The hotel since that date afforded a pleasant temporary home for numberless visitors to the island. At the commencement of the nineteenth century Constant Spring estate was the place selected for his experiments in the improvement of the manufacture of sugar and rum by Dr. Bryan Higgins (miscalled “Wiggins” in Gardner’s “History of Jamaica”), the celebrated physician and chemist, who came to Jamaica in 1797 at the instance of the West India Committee (as related in the issue of the “Circular” for November 6, 1906).
