■C. Veatch now on the U. S. Geological Survey, which also appeared 
in the same publication. 
In 1901, with headquarters in the Helderberg Mts., three side 
trips were taken, viz, lake Champlain, as far as Plattsburg, down the 
Hudson to Rondout, and the Erie canal back to Ithaca. 
The major part of the detailed work of this season was done in 
the Champlain valley. Mr. P. E. Raymond, now fellow in geology 
at Yale, worked out the Crown Point section and during last year 
published the results as No. 14 "Bulletins of American Paleo.:itology". 
He also during that summer began work on the Chazy limestone on 
Valcour island. 
In 1902 camp was again in the Helderbergs. Mr. Raymond con- 
tinued his work on the Chazy of Valcour island. The Bryozoa he 
sent to Yale where he is now working on them, and his other mater- 
ial he sent to Cornell where he expects to work again in the near 
future. 
In the Helderbergs, six weeks were spent in a detailed study of 
the geology of the region. Spirit level lines were run by professor 
Harris from the newly established bench mark at East Berne (U- S. 
G. S.) around through all the sections studied in detail, to the 
N. Y. State Survey triangulation station on top of Countryman hill, 
a distance of at least 12 miles. All lines were run in duplicate. The 
exact hight of each contact line in each section can now be referred 
to mean ocean level. 
Extensive collecting and minute stratigraphic work at Country- 
man hill and Indian Ladder sections occupied the major part of the 
time of the more advanced workers. 
Miss Mignon Talbot, now working over her material at the State 
University of Ohio, spent with aids about six weeks on the Country- 
man Hill section, while the writer with more or less assistance spent 
an equal amount of time on the geology of Indian Ladder; the mater- 
ial collected, he is working up at Cornell. The combined work will 
shortly appear in printed form. 
The last three weeks of the season were spent at Oriskany falls. 
Professor Harris made a detailed topographic map of the region on 
a scale of i in. to 500 feet, and the section was carefully worked by 
Mr. Joviano Pacheco, who had charge of the Water Lime group, and 
Mr. Joviano Pacheco, who was responsible for the Lower Helderberg 
rocks. 
Mention too should be made of the trip on foot from New Salcni 
to Oriskany Falls in company with Dr. H. F. Clcland whereby we 
quite carefully worked a number of sections through the Helderberg 
formations, noting variations in thickness, lithological characters, and 
faunas. This trip made a connecting link between the work at the 
Helderbergs and Oriskany Falls. A Bulletin will be forthcoming on 
the Oriskany Falls section. 
On the way back to Ithaca, stops were made at Manlius and Union 
Springs. Ch.\s. E. SAfiTH.
