2'.i2 lln American Geologist. April, 1894 
Mount Logan, bo named by Prof. I. C Russell in honor of 
Sir Wm, Logan, the founder of the Geological Survey of 
Canada, has been found to excel in bight every mountain peak 
that has been measured in North America. A party under 
Mr. J. E. McGrath was sent out by Supt. T. ('. Mendenball, of 
the U. S. Coast and Geodetic Survey, in ]<s'.)2, to take such 
measurements of angles and distances as would determine the 
hight of Mt. St. Elias. In doing' this measurements were made 
on Mt. Logan, twelve miles toward the northeast from Mt. St. 
Elias. These have recently been computed at Washington 
and result in transferring the honor from Mt. Orizaba in 
Mexico to Mt. Logan. There are three peaks having alti- 
tudes 19,497 ft.. 19,514 ft. and 19,255 feet. Mt. Logan is 
therefore 1,500 feet higher than Mt. St. Elias and 1.200 feet 
higher than Orizaba (Am. Geologist, vol. xn. pp. 213-217, 
Oct.. 1893). 
The International < ongress of Geologists, sixth session, 
to convene at Zurich 29th of August, will continue to Sept. 
2d. having simultaneous sectional meetings and daily general 
ions. The second circular of the arranging committee, 
issued in February, gives the general program and the details 
of the proposed excursions, the latter being intended to be, 
evidently, the chief feature of the meeting. Five excursions 
on foot will take place before the meeting at Zurich and four 
after it. each under a competent guide, the cost of which va- 
ries from ten to fifty dollars. The conductors of these excur- 
sions will lie Dr. II. Schardt, Dr. Aug. Jaccard, M. Louis 
Rollier, Dr. C. Schmidt. Dr. Muhlberg, Dr. Alb. Heim and Dr. 
A. Baltzer. These are intended for those who are hardy 
enough to endure the labor and hardship of actual travel and 
exploration, with hard beds and frugal diet. Two longer ex- 
cursions in the Alps are arranged, one before and one after 
the session, each occupying thirteen days, the former costing- 
sixty dollars and the latter eighty. These are under the di- 
rection of Prof-. Kenevier and Golliez, of Lausanne, and the 
travel will be principally by railroad, by steamboat and by 
stage, occasionally on horse or afoot for short trips aside. 
The excursions which take place before the meeting will start 
from different cities in the western or northern part of Switz- 
erland and will converge at Zurich. Those which occur after 
the session will radiate from Zurich through the Alps and 
unite finally at Lugano, where the close of the Congress will 
take place. These excursions will enable the participants to 
visit the principal classical regions of Swiss geology. The cost 
of membership in the Congress is fixed at five dollars, the pay- 
ment of which i- the only condition. This sum should be 
Bent to the treasurer, M. ("asp. Escher-Hess, Bahnhofstrasse, 
Zurich.
