occur at various depths, but in the cases already noted, between 
the limits of 10 feet and 90 feet. A large tar oe, “however T, 
of the instances on record, have been found at about 80 feet in 
depth, immediately beneath the vance clays that constitute 
the last of the drift series in this re region 
Through all portions of the peat above mentioned, sand and 
pebbles are scattered. The pebbles are mostly of small size, 
seldom larger than a pea, but occasionally three or four inches 
in diameter. They agree in general character with the gravel 
ntry. 
+ the lower extremity of the peat bed, the formation thins

at were brought from the eastward by a torrent-like stream 
deposited over a precipitous bank. 
In pockets of the gravel and also in the clay that ne 
covers the peat, small quantities of vivianite, “blue earth,” 
phosphate of iron, are found. From one of ‘the largest accu- 
mulations of this substance, a tusk or tooth was take 
described as resembling a ‘hog’ s as ale that it was much 
larger. It may also be added that two mastodon tusks, each 
measuring eight feet in length, sate ie in the spring of 
1870, from the northern part of the same drift bed to which the 
peat belongs and at about the same level. 
The reference of the phosphoric acid of the vivianite to ver- 
tebrate bones will, therefore, hardly be questione 
From the above named facts, we seem warranted in conclud- 
ing that the coniferous wood in question grew in the region 
where we find it buried. The amount of the wood renders this 
em and she nature of the remains forbids any other sup- 
ition. In this connection, it is only needful to recall the
