After some time I drew a bill for paving the city, and brought it
into the Assembly. It was just before I went to England, in 1757,
and did not pass till I was gone.<12> and then with an alteration
in the mode of assessment, which I thought not for the better,
but with an additional provision for lighting as well as paving
the streets, which was a great improvement. It was by a private person,
the late Mr. John Clifton, his giving a sample of the utility of lamps,
by placing one at his door, that the people were first impress'd
with the idea of enlighting all the city. The honour of this
public benefit has also been ascrib'd to me but it belongs truly
to that gentleman. I did but follow his example, and have only
some merit to claim respecting the form of our lamps, as differing
from the globe lamps we were at first supply'd with from London.
Those we found inconvenient in these respects: they admitted
no air below; the smoke, therefore, did not readily go out above,
but circulated in the globe, lodg'd on its inside, and soon
obstructed the light they were intended to afford; giving, besides,
the daily trouble of wiping them clean; and an accidental stroke
on one of them would demolish it, and render it totally useless.
I therefore suggested the composing them of four flat panes,
with a long funnel above to draw up the smoke, and crevices
admitting air below, to facilitate the ascent of the smoke; by this
means they were kept clean, and did not grow dark in a few hours,
as the London lamps do, but continu'd bright till morning,
and an accidental stroke would generally break but a single pane,
easily repair'd.
