upper division of this system is represented by conglomerates, sand- 
stones, and marls. The Early Carboniferous rocks are the Calciferous 
sandstone series with associated extrusives of basalt, trachydolerite, 
trachyte, tuffs, and ashy conglomerates and intrusives of essexite, 
teschenite, and analcite dolerite, monchiquite and analcite basalt. 
Following the Calciferous is the Carboniferous limestone series, in the 
middle of which is the Edge coal group, the most important strata 
from an economic point of view in the district. The Upper Carboni- 
ferous is represented by the Millstone grit, which is followed by but a 
slight representation of the true coal measures. At the close of the 
Paleozoic, dikes and sills of dolerite were intruded. During the Pleis- 
tocene, glaciation affected the entire region. 
The petrology of the igneous rocks is thoroughly discussed, and 
numerous analyses are given. The economics of the area consist 
largely of non-metallics, of which coal is the principal product.

2. The sea-level canal upon which estimates were made is to be 
sixty feet wide with a minimum depth of six feet. Its length is 21.76 
miles, a portion of which is along present waterways, and whatever 
excavating will have to be done will be in unconsolidated material. 
The estimated cost for the right of way, excavation, bridges, and dis- 
posal of material is between $2,152,404 and $2,784,887.
