The merchants of Halifax, on 20th July, petitioned the Governor respecting the state of trade, etc., stating that they were agreed to take gold and silver coins at the following values, viz: A Guinea, £1 3 4, Halifax currency; a Johannes, at £4; a Doubloon, at £3 17 6; an Eagle, at £2 10; the old French Guinea, at £1 2, and all the other decimal parts of the same coins at a proportional value; English and old French Crowns, at 5s. 6d; Spanish Dollars, (including those which heretofore passed current at 4s.) at the rate of 5s. At this time British silver was unknown at Halifax--Spanish silver was the current coin. It came up from the West Indies and Spanish America in the course of trade, and the British Government found it more convenient for various reasons to pay their troops stationed here in Spanish silver than to import British coin for that purpose. The names attached to this petition were William Bowie, Garret Miller, Starr & Shannon, Charles Loveland, Moody & Sinclair, Alexander McDonald, William A. Black, Martin Gay Black, John Albro, Charles Boggs, Henry Ford & Co., Henry Austin, Michael Forrestall, Jonathan and John Tremaine, John W. Pyke, Matthew Richardson, Richard Tremain, Samuel Head, M. D., Kidston, Dobson & Telford, H. Taylor, John Liddell & Co., Capel Hines, Jas. Ewing, George W. Mitchell, Prescott Lawson & Co., James Fraser, Winkworth Allen, Smith & Thom, Scaiffe & Baine, R. Lyon, Sr., Andrew Belcher, Forsyth, Black & Co., Lawrence Hartshorne, Charles Hill, Forman Grassie & Co., John Lawson, James Leaver, William Minns, John Osborne and John Owen. A proposition concerning some alteration in Water Street, near the Ordnance Yard, was made by Captain Gustavos Nichols of the Royal Engineers. It was understood that the town would not agree to the proposal unless the Military authorities surrendered a road in continuation of Hollis Street, southward. The subject had been mooted for a long period previous to this time, but no arrangement could be agreed on between the military and the town authorities. Captain Nichols' letter makes an offer according to the plans therein enclosed. This letter and plans are not now forthcoming among the City or Provincial Records, and therefore the particulars of the proposition made by the Engineer Department cannot now be understood. Copies of these plans may possibly exist at the Lumber Yard and Engineers' office.
