Canadian engineer . 12-in. wale on the in-side, and sloping outward at an inclination of 30 to thehorizontal. This uniformity of slope of these outer pilesconsiderably enhances the appearance of the wharft . 12-in. spacing wale was made fast along the entire faceof the wharf, between these springing piles. Mooring piles were driven as shown on the- jjlan. 1 ri< ywere braced tD the four nearest bearjng piles by means of8-in. by 8-in. struts. On the freight wharf two runways were constructed ac-cording to the details shown on the plan. Sliding stringerssupport the removal planks of the flooring over the run-way, so that when not in use the runways may be coveredin. These sliding stringers operate on rollers suspendedfrom the joists of the adjoining portion of the wharf. Theymay be handled by one man quite readily. Throe four-pile clusters were driven at each end of thewharf, the first at the outside corners as a protection to thatportion of the structure, and the two inner clusters in a line,. port Mann Wharf, from tlie River. making an angle of 45 with the face of the wharf. Theseclusters support glance booms, which were placed at thewharf ends to fend off ice in winter, and floating trees, &c.,at freshet time. Owing to the tide causing a change in thedirection of the current during the winter season, the placingof a glance boom at the west end of the wharf was alsonecessitated. The cluster piles were bound together nearthe top with ?4-inch steel cable. Below is given the bill of material for the entire wharf. CANADIAN NORTHERN PACIFIC RAILWAY.
