ties, and numerous well preserved corals and other fossils. It 
is entirely destitute of stratification, and therefore somewhat 
expensive in working; but its density renders it a valuable 
material for filling piers, macadamizing streets and the like, 
for which it will eventually be required. The rock rises in 
detached points from fifty to sixty feet above the lake, sur¬ 
mounted by drift. In the drift sand at Moody's, occur calca- 
\ 
reous and ferruginous concretions of immense size, affecting 
the most fantastic shapes imaginable. They have been formed 
by the filtration of iron and lime among the sand, which by 
some chemical affinities have been attracted so as to bind the 
loose materials together around certain centers. They are 
interesting objects in themselves, and might be used with pic¬ 
turesque effect in landscape gardening. Four miles west of 
the city, near Wauwatosa, the running kilns are in operation, 
the rock is softer and on the west is flanked by some soft fine¬ 
grained encrinal ledges inclining at a high angle. The face 
of the- quarries here is over forty feet. They are immediately 
contiguous to the Bailroad, furnishing ready transportation 
without cartage. The cheapness with which lime may be 
burnt here, its superior quality, and the facilities of transpor¬ 
tation, render these quarries highly valuable. 
The quarries of Emanuel Chase, Esq., one mile east of the 
last, lie immediately below the coralline beds, in what I have 
termed the flag beds of the Niagara. The rock is here in 
regular strata from three to thirteen inches thick, with thin 
shaly partings, or compact with conclioidal fracture; even 
textured of a bluish gray color and intersected by smooth 
seams, the main direction of which is East 30° South. The 
seams are occasionally studded with crystals of pyrites and 
calc spar, and cavities with spar occur. Dip N. E. 15° to 20°. 
Face of quarry about twelve feet. No flints or fossils are 
found. Fractured layers of no value alternating with firm 
stone. This quarry yields excellent stone for steps, window 
caps, pillars, &c. It is easily worked, splitting into blocks of 
almost any size required, and dresses handsomely. The Rail¬ 
road passes within a few feet of the quarry. Thus quarry
