study of the valleys in which these tongues lie shows further 

 that there are no other recognizable terminal deposits in them. 

 The deposits at Cold Spring and at North Otis show some com- 

 plexity, because they are spread up and down the valley a little 

 more than usual, in each case showing earlier and later phases of 

 deposition which are one to two miles apart. But a little 

 experience enables one to recognize the fact that deposits like 

 these are due to the waverings of one halt. 



South of East Lee the deep Tyringham valley comes in from 

 the southeast. Over the col at its head it is continuous with 

 the valley of Clam river, which joins the Farmington at New 

 Boston. Counting the moraines up the valley again from River- 

 ton by way of Clam river, we find the deposit at Tyringham to 

 be the seventh or the same as that at East Lee, with the eighth 

 at Lenoxdale as before. Here we have a branching series in 

 which the first two are common, but north of the second one 

 two parallel branches run up to the seventh. The branches 

 diverge so little that they are not over four miles apart at any 

 point. In a simple branching series like this it can hardly be 

 doubted that the two deposits which stand as No. 4 in each series 

 belong together as parts of one halt line, and the two deposits 

 marked No. 5 as parts of a different later line. No. 6 as parts of 

 still another line, and No. 7 as parts of still another. At Lenox- 

 dale the two branches reunite as one. 



From New Boston another series may be followed more to 

 the west past Montville, New Marlboro, Hartsville, and the 

 Konkapot col to Van Deusenville, where again is found the 

 Lenoxdale moraine, which is the eighth of the series. This 

 series, however, is not quite so good as either of the others, for 

 it does not lie in a single trough or in a pair of head-joined 

 valleys, like the other two, but crosses the hills from the Farm- 

 ington valley to the Housatonic. 



The moraine north of Riverton is easily recognized as part 

 of a line which runs westward to Colebrook. Beginning at this 

 place as No. 2, another series may be followed northwest to Van 

 Deusenville as before, but by a different route through Norfolk, 

 West Norfolk, East Canaan, Ashley Falls, and the hillside south-
