Review of Recent Geologicdl Literature. 271 
Jefferson City, Mo., Sept. 15, 1897. 
Mr. Chamberlain, Editor '^Jonrnal of Geology,'' 
Chicago, Illinois. 
Dear Sir: — A malicious article in your issue for July and August 
under the head of editorials, has recently fallen under my eye. I sent 
the paper to a friend without noting your initials or street, but trust 
this will reach you. 
Primarily, truth is the only objective of science. Since you have ig- 
noi-ed truth entirely in your one-sided editorial, just as your client has 
ignored fundamental facts and definite knowledge in his so-called Geo- 
logical Survey of Missouri, I will say to you that notwithstanding your 
scurillous attack I am still here and ready to cope with either of you on 
any scientific question. As a partisan, a slanderer or a liar, I cannot 
hope to compete with you successfully. But on scientific questions, I 
am always ready for you. 
While your client is on record, in his so-called Geological Reports of 
Iowa and Missouri, and you are on record as his willing champion, the 
only favor I ask is that you persevere until you get all of your kind com- 
mitted. Should you escape the criminal prosecution you so richly de- 
serve for malicious libel and coyotes will count, I shall hope to get be- 
fore the public, ere long, with scalps enough to make myself solid with 
the tax-payers of Missouri. 
The present broad-minded Board gave your friend a fair opportunity 
to get out of Missouri without exposing his incompetency. He failed 
to utilize the opportunity and the office had to be declared vacant. He 
left his tracks, not only in his reports, but in Kansas City, St. Joseph 
and finally in your contemptible editorial. Now if it should transpire, 
despite your partisan effort, that Missouri has eliminated an incubus, a 
parasite or a "scientific" fraud, it will not be the first instance wherein 
a supercilious parasite has unwittingly dug his own grave. It remains 
for an unbiased public to determine whether oi- not yovi and he have 
earned that logical fate. 
I will now renjind you that "every dog has bis day." This is my day 
and the time is not far distant when your client will wish he had carried 
his tracks along with him. That you and he have run up against the 
wrong man, is only a question of time. You can make the most of your 
opportunity and I will pursue the even tenor of my way. 
I am. Sir, 
Jno. a. Gallaher, State Geologiat.
