series of low benches occur, the strongest at 100 feet. At about 140 feeL 

 horizontal gravel overlies finely laminated silty sand, and the gravel, 

 with imbedded boulders, continues to 160 feet. After a low clifE the 

 gravels continue as a flat, at 1?5 feet, to a steep cliff, the front of an 

 outwash plain. At the top of the cliff, on the west side of the road, is 

 the village cemetery, occupying perhaps a couple of acres, perfectly 

 level. On the east side an excavation for gravel exposes a good section 

 of delta structure, with foreset and topset beds. The top of the pit is 

 the height of the cemetery, and the plain, at 200 fest, extends half a 

 mile, to Jordan Pond. The width in the forest is unknown, but it 

 probably fills the valley between the Triad on the east and Jordan Hills 

 on the west. 



This plain, with its declining levels and its structure and it« position 

 facing the sea, is proof of submergence to 200 feet. It does not repre- 

 sent the initial water surface, and the fine sands suggest considerable 

 depth of water. The plain is not connected with any land drainage and 

 was glacial outwash under perhaps 50 feet of water. The Jordan Pond 

 Hotel stands on a stony plateau, a wave-swept moraine, by the map 20 

 feet higher than the sandp]aii:i. It is the moraine built at the edge of 

 the ice which supplied the outwash for the sandplain. 



Along the roads over the hills east of Seal Harbor the gravels and 

 sands occur up to over 225 feet and lie 3^et higher on the County Eoad, 

 reaching to 240 feet southwest of N'ewport Mountain. The water-laid 

 deposits are more abundant in the hollows and localities screened from 

 heavy waves and are increasingly abundant at lower levels. 



Between Seal Harbor and Northeast Harbor plenty of standing-water 

 phenomena occur at high levels. Flying Mountain, two miles north- 

 west of the latter harbor, shows a remarkable flat top contoured at 260 

 feet. 



Extensive exploration of Mount Desert will confirm the fact of sub- 

 mergence to about 250 to 260 feet for the south end and perhaps 300 

 feet at the north end. 



Visits have been made to Portland and Pockland districts, and con- 

 spicuous effects of the sea are found up to 200 feet. The land has too 

 high relief to accept and preserve strong evidences of wave-work at high 

 altitudes. On suggestion of Professor Woodworth, a visit was made to 

 Blackstone Hill, some eight miles north by west from Portland. An 

 excavation in stratified gravels occurs at about 280 feet and gravel with 

 included boulders at 300 feet. The oval hill, probably a drumlin, is 

 smoothed to the simimit, 505 feet. As this is slightly under the theo-
