1878. ] Proceedings of Scientifie Societies. 639 
The following extracts convey an idea of the summer work of 
78: 
Natural History—Members of the Club are requested to care- 
fully observe and record any facts, features, or phenomena in- 
teresting to them, which are connected with the Botany, Zoology, 
Geology, or Meteorology of any mountainous region. Oppor- 
tunity will be given at sectional meetings for the presentation and 
discussion of such items, with the hope “that interesting facts may 
be gathered and collated. 
‘or good general directions, the report of the first Councillor 
in this department, Dr. T. Sterry Hunt, published in Appalachia, 
No. 1, is heartily recommended. Those interested in Botany are 
requested to use Mann’s Lists and Catalogue, which may be ob- 
tained from the Secretary. 
Any reports, communications, inquiries, or specimens designed 
for use in this department of the Club, may be sent to the Coun- 
cillor, William H. Niles, Councillor of Natural History, Cam- 
bridge, Mass. 
Topography.—t. If inclined to do any work with plane-table, 
camera, micrometer-level, barometer, or theodolite, communicate 
with the department concerning instruments and methods. 
State for how long a time the instrument is desired. It is ex- 
pected that members will keep constantly in use the new topo- 
graphical camera presented to the Club by one of our lady 
members, 
2. Signify willingness to aid, in the event of making a system- 
atic occupation of Moat, Osceola, Willey, Agassiz, or some point 
in the north-east. 
One unprovided with special instruments can accumulate 
much valuable material. 
Note the qualifications of a point. to serve as a station of the 
triangulation. 
Having roughly copied (on a large scale) those points in a cer- 
tain region which are shown on any map at hand, sketch in addi- 
tional details. Make the map a complete memorandum in regard 
to one or more classes of objects, such as pata cols, springs, 
pools, streams, water-shed lines, roads, buildin 
ake eye-profiles, with identifications and Boch etl These 
are valuable whether the point be occupied with the camera or 
not. With the aid of a glass make eye-profiles, on a very larg 
scale, of interesting details. When a camera profile has already 
een drawn, visit the spot with a copy made in uniformly light 
lines, and retouch the lines, giving them proper relative impor- 
tance. Also make additional identifications. 
Set signals, with due provision for finding the exact spot in 
case the signal be overthrown. Pole must be vertical. Erect | 
trees may be used by cutting away the lower branches and sym-
