While at Dundee Mr Leslie carried out a further extension of the 
East Pier of Leith, and designed and executed the Wet Dock at 
Montrose and Harbour Works at Arbroath, Kirkcaldy, and various 
other places. He also constructed locks for the Monkland Canal, 
Glasgow, and built a handsome bridge across the Kiver Leven 
in Fife. 
In conjunction with Mr Jardine, the engineer of the Edinburgh 
Water Works, he in 1836 prepared the first water scheme for 
supplying Dundee from the Monikie District. 
In 1846 Mr Leslie removed to Edinburgh, and shortly after that 
he succeeded Mr Jardine as engineer to the Edinburgh Water 
Company. In 1849-50 he designed and carried out a plan for 
taking empty boats afloat up an inclined plane at Blackhill, for 
the Monkland Canal, Glasgow, thereby saving both time, labour, 
and much water, as compared with the usual method of lockage. 
In 1852 Mr Leslie, in connection with Mr J. M. Kendel and Mr 
Mackain, was engineer for a scheme for supplying Glasgow with 
water from Loch Lubnaig, for the Glasgow Water Company. This 
scheme, however, did not pass, having been keenly opposed by the 
Corporation of Glasgow, who shortly after that took over the 
control of the Water Works from the Company. 
The first of the more important works carried out by Mr Leslie, 
after his appointment as engineer to the Edinburgh Water Com- 
pany, was the construction of the Torduff, Clubbiedean, Bonally, 
and Loganlea Beservoirs, and the heightening of the embankment 
of the Glencorse Reservoir. 
In 1856, under Mr Leslie’s care, the Bill for appropriating the 
Colzium Springs was carried through Parliament, and under its 
provisions the Harperrig Reservoir, for providing compensation to 
the Water of Leith, was constructed ; and in 1863 a further supply 
was introduced under his superintendence from the Crosswood 
Springs. 
In 1870, when the Corporation of Edinburgh took over the 
business of the Water Company, the newly-constituted Water 
Trust elected Mr Leslie consulting engineer, and at the same time 
appointed Mr J. W. Stewart resident engineer. Mr Leslie was 
instructed to report on all the available sources of additional supply 
for the city, which had already been reported on by Mr Stewart,
