of lime which are presented to view. The greater number of the veins 
are but a line or two in width; few only attain to the same number of 
inches. No determinate direction governs them. Some of the veins, 
besides the carbonate of lime, contain small particles of sulphuret of 
lead, or galena; others, pyrites, and in some rare instances, a little sul- 
phuret of zinc, or blende. 
The first workings met with in ascending the creek, at the time I was 
there, were the most promising; and should the excavation continue for 
about 15 or 20 feet in perpendicular depth, the Trenton limestone, 
which underlies the shale, will be reached, and then an opportunity will 
be afforded of knowing the influence which the rock containing the veins 
has upon the veins themselves. 
Above these veins, on the same side of the creek, there is an inte- 
resting and beautiful cluster of veins, made up of pyrites chiefly, verify- 
ing the saying that " all is not gold that glitters." It was from amongst 
these veins that the large piece of lead ore, deposited, as we were inform- 
ed, in the office of the Treasurer of the State, was taken. Beyond this 
working, on the opposite side of the creek, others were being made; but 
as I apprehend, like all the veins of this creek, as well as all others yet 
visited, will add more to knowledge than pecuniary profit. 
The mine on East Canada creek, to which Mr. Conrad last year was 
denied admittance, was this year fully open to inspection. It owes its 
origin to one of the most interesting of the uplifts of the Mohawk valley, 
promising at no distant period to become one of the classic points of 
geology. 
From the bridge over East Canada Creek, at Manheim village, the 
aolciferous sandrock appears, forming the left ascending bank, also the 
falls of the creek; and on the right bank of the creek, at the foot of the 
falls, it rises perpendicularly, with the birdseye superimposed, the two 
rocks attaining the height of about 30 or more feet. On that side of the 
creek, the black shale comes up from the bridge, with the same small 
dip as the calciferous, namely to the southwest, and terminates abrupt- 
ly, by a curve upwards, against the calciferous and birdseye, exhibiting 
the Trenton limestone beneath at its point of curvature. Thus we have 
on the same parallel, forming the opposing sides of the same creek, two 
very different and dissimilar rocks, as to age, composition, and fossil 
contents.
