weathered over 2 to 5 feet from the surface. Many instances have been 

 observed, but a few will suffice as examples. 



In Orange, Franklin county, Massachusetts, on the road to Warwick, 

 there is an excellent road section showing several feet of clayey till of 

 Montauk type, but that it is probably of Wisconsin age is shown by the 

 fact that it is yellowed only 1 to 2 feet at the top and has a sharp line of 

 demarkation from the unoxidized blue till below. 



Along the Boston and Albany railroad just east of Palmer, Hampden 

 county, Massachusetts, a new excavation in 1906 showed 3 to 5 feet of 

 yellowed till,' below which it is blue. 



At Arlington Heights, near Boston, sections of till have been seen which 

 were only oxidized about 2 to 3 feet.

A, fine stratified gravel; B, poorls' stratified gravel, with some boulders up to C

One mile northwest of Milbridge, Maine, a 10-foot section of till

On Ocean drive. Mount Desert island, between Bar Harbor and Ottar

 the surface are yellowed. ' 



Midway between the villages of Deer Isle and South Deer Isle, Maine, 

 is a 10-foot section which is oxidized only 18 inches at the top. 



On the north side of Little Chebeague island, Casco bay, is a nearly 

 vertical 40-foot bluff of till which is oxidized only 2 to 3 feet. 



Four miles south of Calais, Maine, there is a section of till which is 

 oxidized only 3 to 5 feet, the rest of the exposure being blue in color. 



5. Veneers of this till over Montauk till. — In certain localities this till
