air from before the fire, and
be soonest tempered by the mixture. The same kind of shelf should
also be placed here. Another way, and not a very difficult one, is
to take out an upper pane of glass in one of your sashes, set in a
tin frame, (Plate, Fig. 2.) giving it two springing angular sides,
and then replacing it, with hinges below on which it may be turned
to open more or less above. It will then have the appearance of an
internal sky light. By drawing this pane in, more or less, you may
admit what air you find necessary. Its position will naturally throw
that air up and along the ceiling. This is what is called in France
a _Was ist das?_ As this is a German question, the invention is
probably of that nation, and takes its name from the frequent asking
of that question when it first appeared. In England, some have of
late years cut a round hole about five inches diameter in a pane
of the sash and placed against it a circular plate of tin hung on
an axis, and cut into vanes, which, being separately bent a little
obliquely, are acted upon by the entering air, so as to force the
plate continually round like the vanes of a windmill. This admits the
outward air, and by the continual whirling of the vanes, does in some
degree disperse it. The noise only, is a little inconvenient.

2. A second cause of the smoking of chimneys is, _their openings
in the room being too large_; that is, too wide, too high, or
both. Architects in general have no other ideas of proportion
in the opening of a chimney, than what relate to symmetry and
beauty, respecting the dimensions of the room;[52] while its true
proportion, respecting its function and utility depends on quite
other principles; and they might as properly proportion the step
in a stair-case to the height of the story, instead of the natural
elevation of men's legs in mounting. The proportion then to be
regarded, is what relates to the height of the funnel. For as the
funnels in the different stories of a house are necessarily of
different heights or lengths, that from the lowest floor being
the highest or longest, and those of the other floors shorter and
shorter, till we come to those in the garrets, which are of course
the shortest; and the force of draft being, as already said, in
proportion to the height of funnel filled with rarefied air; and a
current of air from the room

At his house I lay that night, and the next morning reached Burlington, but had the mortification to find that the regular boats were gone a little before my coming, and no other expected to go before Tuesday, this being Saturday; wherefore I returned to an old woman in the town of whom I had bought gingerbread to eat on the water, and asked her advice.

I had shown an obliging readiness to do her some little services, which impressed her, I suppose, with a degree of good will toward me; therefore, when she saw a daily growing familiarity between me and the two young women, which they appeared to encourage, she took me aside, and said, "Young man, I am concerned for thee, as thou hast no friend with thee, and seems not to know much of the world, or of the snares youth is exposed to.

Had he been in my opinion a good preacher, perhaps I might have continued, notwithstanding the occasion I had for the Sunday's leisure in my course of study; but his discourses were chiefly either polemic arguments or explications of the peculiar doctrines of our sect, and were all to me very dry, uninteresting,.

After dinner, when the company, as was customary at that time, were engaged in drinking, he took me aside into another room, and acquainted me that he had been advised by his friends in England to cultivate a friendship with me, as one who was capable of giving him the best advice, and of contributing most effectually to the making his administration easy; that he therefore desired of all things to have a good understanding with me, and he begged me to be assured of his readiness on all occasions to render me every service that might be in his power.

"Some time since there fell into my hands, to my great joy, about twenty-three sheets in thy own handwriting, containing an account of the parentage and life of thyself, directed to thy son, ending in the year 1730; with which there were notes, likewise in thy writing; a copy of which I inclose, in hopes it may be a means, if thou continued it up to a later period, that the first and latter part may be put together; and if it is not yet continued, I hope thee will not delay it.
