6. Charcoal fires in pots are used chiefly in the shops of
handicraftsmen. They warm a room (that is kept close, and has no
chimney to carry off the warmed air) very speedily and uniformly; but
there being no draught to change the air, the sulphurous fumes from
the coals [be they ever so well kindled before they are brought in,
there will be some] mix with it, render it disagreeable, hurtful to
some constitutions, and sometimes, when the door is long kept shut,
produce fatal consequences.

To avoid the several inconveniencies, and at the same time retain all
the advantages of other fire-places, was contrived the Pensylvania
fire-place, now to be described.

This machine consists of

A bottom-plate, (i) (_See the Plate annexed_.)

A back plate, (ii)

Two side plates, (iii iii)

Two middle plates, (iv iv) which, joined together, form a tight box,
with winding passages in it for warming the air.

A front plate, (v)

A top plate (vi)

These are all cast of iron, with mouldings or ledges where the
plates come together, to hold them fast, and retain the mortar used
for pointing to make tight joints. When the plates are all in their
places, a pair of slender rods, with screws, are sufficient to bind
the whole very firmly together, as it appears in Fig. 2.

There are, moreover, two thin plates of wrought iron, viz. the
shutter, (vii) and the register, (viii); besides the screw-rods O P,
all which we shall explain in their order.

(i) The bottom plate, or hearth-piece, is round before, with a
rising moulding, that serves as a fender to keep coals and ashes from
coming to the floor, &c. It has two ears, F G, perforated to receive
the screw-rods O P; a long air-hole, _a a_, through which the fresh
outward air passes up into the air-box; and three smoke-holes B C,
through which the smoke descends and passes away; all represented
by dark squares. It has also double ledges to receive between them
the bottom edges of the back plate, the two side-plates, and the two
middle plates. These ledges are about an inch asunder, and about
half an inch high; a profile of two of them, joined to a fragment of
plate, appears in Fig. 3.

(ii) The back plate is without holes, having only a pair of ledges on
each side, to receive the back edges of

Thomas was bred a smith under his father; but, being ingenious, and encouraged in learning (as all my brothers were) by an Esquire Palmer, then the principal gentleman in that parish, he qualified himself for the business of scrivener; became a considerable man in the county; was a chief mover of all public-spirited undertakings for the county or town of Northampton, and his own village, of which many instances were related of him; and much taken notice of and patronized by the then Lord Halifax.

[10] My mother, the second wife, was Abiah Folger, daughter of Peter Folger, one of the first settlers of New England, of whom honorable mention is made by Cotton Mather,[11] in his church history of that country, entitled _Magnalia Christi Americana_, as "_a godly, learned Englishman_," if I remember the words rightly.

His ducking sobered him a little, and he went to sleep, taking first out of his pocket a book, which he desir'd I would dry for him.

I never went out a fishing or shooting; a book, indeed, sometimes debauch'd me from my work, but that was seldom, snug, and gave no scandal; and, to show that I was not above my business, I sometimes brought home the paper I purchas'd at the stores thro' the streets on a wheelbarrow.

postponing the further prosecution of it at that time; and my multifarious occupations, public and private, induc'd me to continue postponing, so that it has been omitted till I have no longer strength or activity left sufficient for such an enterprise; though I am still of opinion that it was a practicable scheme, and might have been very useful, by forming a great number of good citizens; and I was not discourag'd by the seeming magnitude of the undertaking, as I have always thought that one man of tolerable abilities may work great changes, and accomplish great affairs among mankind, if he first forms a good plan, and, cutting off all amusements or other employments that would divert his attention, makes the execution of that same plan his sole study and business.

Our articles of agreement oblig'd every member to keep always in good order, and fit for use, a certain number of leather buckets, with strong bags and baskets (for packing and transporting of goods), which were to be brought to every fire; and we agreed to meet once a month and spend a social evening together, in discoursing and communicating such ideas as occurred to us upon the subjects of fires, as might be useful in our conduct on such occasions.

But, if the demand was not directly from the crown, that phrase was found not so proper, and some other was to be invented.

He was zealous and active in endeavouring to procure subscriptions for it, but the proposal being a novelty in America, and at first not well understood, he met but with small success.

He had been brought up to it from a boy, his father, as I have heard, accustoming his children to dispute with one another for his diversion, while sitting at table after dinner; but I think the practice was not wise; for, in the course of my observation, these disputing, contradicting, and confuting people are generally unfortunate in their affairs.

David Hume,[100] too, who was some years after secretary to Lord Hertford, when minister in France, and afterward to General Conway, when secretary of state, told me he had seen among the papers in that office, letters from Braddock highly recommending me.

Our axes, of which we had seventy, were immediately set to work to cut down trees, and, our men being dexterous in the use of them, great despatch was made.

If you were a Servant, would you not be ashamed that a good Master should catch you idle? Are you then your own Master, _be ashamed to catch yourself idle_.
