region between Lake Champlain and the 

 Adirondacks. 



Dr. Lane, the retiring vice-president, will 

 deliver his presidential address during the 

 meeting. Several informal talks will be given 

 on subjects germane to the field excursions, 

 during the half hours after lunches. Papers 

 may be expected from Professors Fairchild, 

 Davis, Kemp, Gushing, Woodworth, Hudson 

 and others. 



Dr. John M. Clarke will give a paper on 

 ' Lake Champlain ' including an account of 

 the work of the state in the Champlain Valley 

 which is classic ground in the history of 

 American geology. The region is the field of 

 three great wars and many bloody encounters 

 before them and the records of these events are 

 locked up in some measure in the place 

 names of the country. The section owes much 

 to Dr. Clarke for his careful planning of the 

 meeting so that visiting geologists will see as 

 much as possible of this extremely interesting 

 region. 



The program of excursions is as follows : 



Wednesday, July &■ — Preliminary trip. 

 Preceding the first day of the regular trips 

 Professor Woodworth will conduct those who 

 desire to visit ' The Gulf ' at Corey Hill, 

 Canada, to that locality, passing over the 

 marine beaches along the international bound- 

 ary. Persons intending to take this trip 

 should reach Mooers the night before. This 

 party will join the other members at West 

 Chazy for the Altoona excursion. As this trip 

 must be made in wagons, the number is 

 limited to twenty-five persons. 



Thursday, July J/.. — Trip to Altoona, Mooers 

 Junction. Plattsburg to West Chazy by 

 train ; drive to Cobblestone Hill ; Altoona spill- 

 way on Potsdam sandstone; to Altoona delta; 

 thence down the Big Chazy to study the fossil 

 shore lines, to Mooers, where the party will 

 spend the night. Only twenty-five persons 

 can be accommodated in the wagons; others 

 may walk four and one half miles from West 

 Chazy to Cobblestone Hill and the Altoona 

 spillway. Guide, Professor Woodworth. 



Friday, July 5. — From Mooers Junction to 

 Chazy. The Chazy limestone in its varying 

 aspects and its faults. If this trip is to be 



made it will be necessary to start in the morn- 

 ing, as there is no other train between the two 

 places. Return to Plattsburg in the evening, 

 to Hotel Champlain or the Catholic Summer 

 School. Guides, Professor Cushing and Dr. 

 Ruedemann. 



Saturday and Sunday, July 6 and 7- — By 

 steam-launch to Crab Island, Valcour Island 

 and Valcour shore. Extensive displays of 

 Paleozoic sediments with interesting struc- 

 tural features. Return Saturday evening to 

 spend Sunday at Blufi Point, at Hotel Cham- 

 plain, or the Catholic Summer School. In- 

 teresting exposures of the Trenton faulted 

 down against the Chezy and of monchiquite 

 dikes in the limestone, within easy walk of the 

 hotel. Guides, Professor Cushing, Dr. Ruede- 

 mann and Professor Hudson. 



Monday, July 8- — Plattsburg to Lyon Moun- 

 tain by rail. The entire day to be given up 

 to the examination of the magnetite mines. 

 It may be possible to make stops at interest- 

 ing localities : Dannemora, Cadyville, but this 

 will depend upon convenience. Return to 

 Plattsburg. Guide, Mr. Newland. 



Tuesday, July 9- — Keeseville; Anorthosite 

 and Potsdam conglomerate; north slope of 

 Trembleau Mountain, Marine delta, and higher 

 lake shores; thence to Ausable chasm cutting 

 the Potsdam sandstone since the retirement 

 of Hochelogan Sea. Return in the evening 

 to Plattsburg. Guides, Professors Woodworth 

 and Cushing. 



Wednesday, July 10. — ^Plattsburg to Port 

 Henry and Mineville iron mines, or to Ticon- 

 deroga and the graphite beds. It is not likely 

 that both trips could be made on the same 

 day. Each one will choose which excursion 

 he will take. The Port Henry and Mineville 

 trip will be under the guidance of Mr. New- . 

 land, the Ticonderoga trip under the guidance 

 of Professor Kemp. 



Thursday, July 11. — If any of those who 

 attend the meeting would like to spend another 

 day in visiting points of interest on Lake 

 George on the way home. Professor Kemp has 

 kindly consented to act as guide for this 

 excursion. 



There will be a winter meeting of the 

 American Association in Chicago, when there
