The Legislature of these years made very considerable additions to the power of the Trustees; allowing them to borrow money on the credit of the town, to purchase and hold real estate for erecting market-houses, wharfs, &c., to levy a tax on exchange brokers, to tax hacks, drays, &c., to appoint harbor and wharf masters, and make rules governing the lading and unlading of vessels, to collect wharfage fees, to appoint inspectors of flour, &c. The first use made of this new power was the purchase of ground for a wharf. Rowan owned a slip of ground lying north of Water Street, commencing at Second and terminating at Seventh Street. A similar slip, lying between Seventh and Eighth streets, was already the property of the city. This slip the city agreed to add to Rowan's, and also to pave the whole as a wharf, using the stone in Rowan's quarry, situated on the premises, and for the wharf so constructed they agreed to give to Rowan and to his heirs _forever_, in semi-annual payments, one-half the receipts of this wharf. They also agreed that, if at any time Gray's wharf, lying east of Second Street, should be bought, both parties might unite in the purchase and Rowan should receive as before one half the profits of the entire wharf. This contract; made with but a single dissenting voice on the part of the Trustees, that of Jeremiah Diller, must have been the result of either a very low state of finances or of very injudicious precipitation. Rowan's heirs, it is understood, now get but one fourth of the wharfage, but even this would have been a sum better gained to the city than lost by a want of proper judgment or foresight.
