c. That the committee be authorized to 
draw upon’ the secretary-treasurer for its 
expenses of printing, ete., up to a limit of 
$20.00. 
The Society voted to approve this plan with the 
proviso that the Committee should submit to the 
mempers by mail a preliminary printed report, and 
should be guided by any opinion submitted by a 
majority of the members. The president appointed 
Messrs. Ganong, Lloyd and Atkinson such a com- 
mittee. The preliminary report of the committee is 
now ready, and will be sent to members of the So- 
ciety and to others known to be interested. Others 
wishing to see the report may obtain copies by ap- 
plication to the writer. The appearance of the final 
report will be announced through SCIENCE.

THE MICHIGAN ACADEMY OF SCIENCE. 
THe seventh annual meeting of the 
Michigan Academy of Science was held at 
the University of Michigan, Ann Arbor, 
Mareh 28th, 29th, and 380th, under the 
presidency of Professor Chas. E. Barr, of 
Albion College. 
The general session of Thursday after- 
noon, March 28th, was devoted to the geolog- 
ical and archeological surveys of the State. 
The Secretary read a paper by Mr. Harlan 
Smith, of the American Museum of Natural 
History, on ‘An Archeological Survey of 
Michigan,’ and Mr. Geo. W. Bates, presi- 
dent of the Detroit Archeological Society, 
presented a second paper by Mr. Smith, on 
‘The Antiquities of Michigan, Their Vaiue 
and Impending Loss.’ This paper described 
many of the archeological remains of Mich- 
igan, and urged that steps should be taken 
to preserve them. (At a later meeting the 
Academy endorsed a bill now before the 
Legislature, providing for an archeological 
survey of the State.)

[N. 8. Vou. XIII. No. 329. 
Dr. A. C. Lane presented a paper (read 
by the Secretary) on ‘Recent Work of the 
State Geological Survey,’ and Mr. Frank 
“Leverett, of the U.S. Geological Survey, 
gave an account of ‘Glacial Investigations in 
Michigan.’ These papers showed that the 
Government and State Surveys are cooper- 
ating, and supplementing each other’s work 
in many respects. The State Survey is de- 
voting itself chiefly, in the lower peninsula, 
to the study of marl, and to a correlation of 
the various coal seams; in the upper penin- 
sula to a correlation and study of the cop- 
per-bearing lodes. Mr. Leverett’s paper 
presented certain economic and scientific 
results of the U. S. Geological Survey, par- 
ticularly in the mapping and interpreta- 
tion of topographic features, and in varia- 
tions in the structure of glacial deposits. 
The successive positions of the margin of 
the glacial ice were shown to be marked by 
moraines or massive belts of rolling coun- 
try which are found to sweep around the 
basins of Lake Michigan, Saginaw Bay 
and Huron-Hrie. These carry on their 
outer borders more or less extensive plains 
of gravel and sand, which were formed by 
the outflowing waters of the melting ice- 
sheet. The distribution of these moraines 
and bordering gravel plains indicates that 
the first counties of Michigan to be uncoy- 
ered by the melting back of the ice are 
Branch, St. Joseph, Kalamazoo and Cal- 
houn, and the water from the ice then 
flowed to the Kankakee River, past South 
Bend, Ind. The ice margin melted back 
from these counties toward the lake basins 
to the west and north and east, and after a 
time it shrunk within the present limits of 
the Great Lakes. The lake history con- 
nected with the present system of Great 
Lakes is very complicated and as yet but 
partially worked out. 
The Academy then divided into sections 
of botany, zoology, sanitary science and 
agriculture, and sectional meetings were
