The streams, therefore, are directed by hugenozzles so as to undermine the lower part of the bank, andthe weight of the material above brings down the sand andgravel from the working face. From here it is washedthrough the sluice way into Guilds Lake, as shown inFig. I. The trestle supporting the sluice through which thedebris is conducted to the lake also supports two 18-inchpipes carrying the water pumped from the same lake. is a general view of the site, showing how far the workhad progressed by April 27th, 1910. The trestle is shownextending through the old Lewis and Clark Expositiongrounds to Guilds Lake, where the fill is being Fig. 2. Fig. 2 shows Goldsmiths Hill from the corner ofRaleigh and Twenty-ninth Streets on March i6th, 1910, be-fore operations on it began. By November 3rd following,work was well under way, as is shown by Fig. i. Iimight be mentioned that in some places the height of thebank to be reduced was 140 feet. The pump house, a temporary structure, of course, islocated near the lower end of the trestle. Its foundationswere laid in the bottom of the lake at low water before anyfilling had been done. Now, however, the pump house isin the middle of a filled tract of several acres. The contractors, the Lewis-Wiley Company, are carry-ing on the work day and night with no interruption exceptfor Sundays. It is expected that by the spring of 1913 the so-calledGoldsmiths Hill will be no more and that its site will besuitable for no less than 300 residences, while the operationwill reclaim to the city several acres of land from GuildsLake, half a mile away.
