drawings and defcriptions. One particu- 
lar advantage, which this mode has over 
the common one, is, that no attendance 
will be neceffary from the firtt fetting to 
work to the completion of the fame, nor 
even then will the neglect of a few hours 
be produétive of the leaft injury to the 
work. But, in the common method of 
boring, attendance muft be conftantly 
given by one or two perfons, either to 
prefs forward the cutters by hand and Je- 
ver, or frequently to change the pofition 
of the levers in the axis of the pinions, 
and to raife the weights, &c. and, fhould 
any neglect occur in the finifhing cour‘e, 
the cylinder, at leaft, muft be bored again, 
if it be not irreparably injured.

ing the building, utenfil, or apparatus de- 
ficned, that their fides or edges, when 
made and completed fhall join and fit to 
each other on an exact radius of a circle, 
terminating at its center, fo that, when 
all the faid parts are put together, with or 
without mortar or cement, the faid feveral 
clumps will form a direét circle, bearing — 
preflure inwards on the principle of an 
arch ; and that, when the feveral layers,. 
courfes, or ditin& circles thereof fhall be 
fitted and adjafted in their proper places, 
fuch will form what is termed a broken 
joint in the wall or fhell, fo that the fame 
will alternately clamp or join the courfes 
next adjacent to them together, to prevent 
their removal fideways ; and, being fitted 
to each other on their flat fides, alternate 
male and female, by means of fhoulderings 
and abutments, the wall or fhell of the build- 
ing, pipe, tunnel, &c. of which they are 
made is clamped together in one entire com- 
bination, capable of refifting the preflure of 
confiderable force in every direétion. The 
method is adapted to the building of cot-

and of eight foreign aflociates. . The 
feétions to be compoled and defignated as
