The Geology of the Perry Basin in Southeastern Maine. By George 
Otis Smith and David White. U. S. Geol. Survey, Professional 
Paper No. 35. Pages 107, with 6 plates. 1905. 
The earliest report of Dr. Charles T. Jackson on the geology 
«of Maine, in 1837, recommended boring for discovery of coal in the 
sandstone formation bordering the west side of Passamaquoddy 
bay, in the vicinity of Perry, that formation being supposed to be a 
continuation of the bituminous coal series of New Brunswick. 
Later, on the evidence of fossil plants, the Perry beds were regarded 
by W. B. Rogers, Newberry, C. H. Hitchcock, J. W. Dawson, and 
others, as of upper Devonian age, being thus older than any known 
rocks containing commercially workable coal. But citizens of that 
district, deeming the question yet undecided, petitioned the state 
legislature two years ago for an appropriation to be expended in 
drilling for coal, which led to the special survey reported in this 
paper. 
The Perry formation is found to comprise, in ascending order, 
a lower conglomerate, a lower lava, an upper sandstone, and an 
upper lava. There has been no very marked folding and but slight 
alteration of the beds; and their age is shown to be distinctly 
upper Devonian, and probably Chemung. It is certain that they 
contain no workable coal deposits. w - U.
