404 The American Geologist. Doccmbcr, 1897 
suits are seen in the revival of geologiy.'il science already al- 
luded to. Geological societies, surveys and journals have mul- 
tiplied. Nearly every educational centre, if not ever}' impor- 
tant educational institution in the land has its own means of 
publishing its geological researches. The earth was never 
probed so thoroughly, and its secrets discovered so rapidly as 
to-day. 
With the present rapid scientific and intellectural develop- 
ment in the United States and in the world is a promise of 
greater progress in the future. We may e.xpect reasonably' 
that the movement now under way will not be checked till the 
utmost bound of the capacity of human progress is reached. 
We will not say that bound is in the infinite distance, but we 
are satisfied that it is as yet far ahead of us. The record of 
the years and centuries that will intervene will be marked by 
many failures as well as by victories, but at last truth only 
will reign, truth wrenched from nature in its highest expres- 
sion, based on scientific research and established and perpet- 
uated by the zeal and often by the self-sacritice of its vota- 
ries. Among these votaries the geologist, the astronomer, the 
chemist and the physicist of every name, who contributes to 
the general advance, will occupy no mean rank. 
The American Geologist has taken part, during the past 
ten years, in this movement, and has aided it so far as its ed- 
itors have had opportunity, and so far as their numerous of- 
ficial duties would permit. In this they have l)een encouraged 
during the five years last passed as during the previous five, 
by the cheerful assistance of numerous fellow-geologists who 
have tendered their papers for publication, and who have oth- 
erwise assisted them in maintaining the journal. To these the 
editors wish to express their thanks. 
In the last ten volumes of the Geologist, two hundred and 
twenty-seven contributed articles have been published, not 
the product of the editors. One hundred articles have been 
(!ontributed by the editors, as well as sixty-six articles of "Ed- 
itorial Comment;" and there have been described sixty-seven 
new species and genera. This takes no account of "Correspon- 
dence" nor of "Reviews." 
The editors can make no jjromises for the future, other 
than that which is deducible from the past. On that basis
