long by 6 deep and 4 wide. This saves the expense of digging and 
hauling coal. 
Subsequently, Messrs. Warth & English, whose works are on the 
opposite side of the river, obtained a similar stream of gas, which has 
been used successfully in the same way ; and more recently Mr. Dryden 
Donnally, Mr. Charles Reynolds, and some few others, produced a 
partial supply of gas to heat their furnaces in the same way. 
But the most remarkable phenomenon in the way of natural gas 
here, and we have no doubt in the whole world, is that at the works 
of Messrs. Dickinson & Shrewsbury, which has been exhibited for 
nearly two months past. In this well the gas was reached at the 
depth of one thousand feet. What the upward pressure of the gas 
to the square inch is, through the aperture, which is three inches in 
diameter, we are unable to tell, and perhaps it would be impossible to 
ascertain. It has never had a free and unobstructed vent. There is 
now at the bottom of the well an iron sinker, a long piece of round iron 
nearly filling the aperture ; on this are 600 pounds of iron, and about 
300 feet of auger-pole used in boring, in pieces of 10 and 20 feet in 
length, with heavy iron ferules on the end, screwed into each other. 
Notwithstanding all this obstruction, a stream of water and gas issues 
up through a copper tube, 3 inches in diameter, inserted into the well 
to the depth of 500 feet, with the noise and force of steam genera- 
ted by the boilers of the largest class of steamboats. It is computed 
that a sufficient quantity of gas comes from this well to fill, in five min- 
utes, a reservoir large enough to light the city of New York during 
twelve hours, When we reflect that this stream of gas has flowed, un- 
abated, for nearly two months, what must be thought of the quantity 
and the facility of manufacturing it down below! In the springs hard 
by, and in the other wells, (with perhaps the exception of that of one 
or two others,) there appears, as yet, to be no diminution in the quantity 
at any place where it has heretofore been known to exist. 
5. Bromine and Iodine:—Prof. W. W. Matuenr, at Athens, O., writes 
under date of Jan. 20, 1845—* I have found bromine and iodine in the 
bittern of the salt springs of this vicinity. They are not very abundant, 
but by improved methods of extraction, I can supply any demand for 
bromine or its common combinations; { can supply it as cheap as any 
one. I have extracted bromine pure, and formed various compounds 
with it, as bromide of iodine, hydrobromic acid, hydrobromates of 
potassa and soda, bromates of potassa, soda and of lime.” 
We with pleasure record this fact, and can add that we have received 
similar statements from Pittsburg, im. Pennsylvania, and other places in 
e west. F : F
