244 The American Geologist. April, 1902. 
fortunate that the name Maxville, applied to the limestone in 
Ohio, by E. B. Andrews in 1869, has been overlooked. That 
geologist recognized the true relations of the deposit at once 
and his conclusions were confirmed in the following year by 
F. B. Meek, who had just completed the study of a collection 
made by the writer from the same limestone in northern West 
Virginia. Andrews traced the limestone through southeastern 
Ohio into Kentucky. The adoption of this name would be not 
only a recognition of the law of priority but it would be also 
a just recognition of a faithful geologist, whose work, for the 
time, was of high order. 
It is now upwards of thirty years since the writer collected 
the fossils in West Virginia upon which Meek based his de- 
terminations. No effort was made at that time to ascertain 
the distribution of the forms, but, as was the habit in those 
days, all the specimens from all parts of the deposit were 
bundled up together. For the first time, in this interyal, an 
opportunity was afforded last summer for careful examination 
of the limestone. The National road, leading from Washing- 
ton to St. Louis, and constructed in the early part of the last 
century, was macadamized in eastern Fayette county of Penn- 
sylvania with stone from this deposit, most of the material hav- 
ing been obtained from Snyder's quarries on the easterly slope 
of Chestnut (now commonly known as Laurel) ridge and seven 
miles southeast from Uniontown. The exposure in these 
quarries has been increased greatly within a few years, as 
the farmers for many miles around resort to it for limestone, 
so that now the upper part of the deposit is well shown. In 
studying this locality, no attempt was made to measure the 
overlying shales, as that work can be done only by instrumental 
survey, but the interval to the Pottsville conglomerate is ap- 
proximately 200 feet. Fully one-half of this, however, be- 
longs to the Sharon coal group, which here is continuous with 
the Lower Carboniferous as the bottom plate of the Potts- 
ville is absent. The collection of fossils was submitted to Dr. 
Stuart Weller of Chicago University, who not only gave the 
list of forms but also offered some notes respecting correla- 
tion, which will be presented in a later portion of this paper.
