112 TERRACES. 



plain upon which the State Prison is located is No. 4 ; while the Cemetery occupies both Nos. 3 and 4, and 

 the principal street running north and south is upon No. 3. The railroad passes on No. 1, the meadow. 

 A map of all these terraces is given on Plate IV, Fig. 3. 



North of Windsor, on the road to Hartland, the above section, Fig. 57, shows the occurrence of seven 

 terraces. They were probably formed by a former bed of Connecticut river, passing around an isolated 

 elliptical-shaped No. 2 terrace, which will be seen on the map just referred to, a little north of Windsor 

 village. In this case the Connecticut has worn away materials from one of its own terraces, and has 

 arranged them in this form. Though the highest terrace here is the seventh on the section, it is placed 

 on the map as connected with No. 6, above and below tin's point, and it is of the same height with 

 them. Hence we consider it as the sixth terrace, as a whole, and the seventh in this particular place. 

 This high terrace, as the section shows, has been partially worn away. There is no stream in this valley, 

 but it seems to have been eroded by rains, which have marred the outlines of the higher terraces so much 

 all along the river. This valley is not an old bed of the river, for it is not continuous to the river. This 

 section was measured with the Aneroid, which did not work very satisfactorily. It does not give small 

 heights very correctly. 



The higher terraces occupy most of the surface of the valley to North Hartland, except where small 

 tributary streams have worn a passage through them, as at the village of Hartland, or meadows have been 

 formed by the former bed of the Connecticut. The material of the highest terrace is sand, and the lower 

 terraces are formed of clay. 



At North Hartland the Otta Quechee River unites with the Connecticut, and the map shows that a large 

 part of the higher terraces has evidently been worn away, leaving a pretty basin of the smaller terraces in 

 FIG. 58. their place. The adjoining figure (Fig. 58) repre- 



sents a section of the terraces formed by the conflu- 

 ence of the two rivers. The section runs just north 

 of North Hartland depot, and south of the Otta Que- 

 chee. The depot is upon the same level as No. 3, in 

 the section. The meadow is quite extensive here. 

 This section was measured with the Aneroid. It is 

 interesting to notice that No. 6 of this section is of 

 nearly the same height as No. 6 of the previous figure, 



section of Terraces at the confluence of otta Quechee and (57), differing only three feet ; and that No. 4 of this 



section, and No. 3 of the previous, differ in height only 



one foot. This may not be the result of accident. Upon the New Hampshire side of the river, the terra- 

 ces are few, or of small size in the ninth basin, until we reach the town of Lebanon, above the mouth of the 

 Otta Quechee, where the meadow is very wide, and four large terraces occur beyond it. The valley is quite 

 wide here, but narrows quite rapidly to White River Junction, and then more gradually to the limit of the 

 basin, at the line between Hartford and Norwich, where mica and hornblende schists form the banks. 



The section in Fig. 59 was measured by us in 1854, with the Aneroid barometer belonging to Dr. 

 Hitchcock, whose range has been more accurately determined than that of the instrument belonging to the 

 surveying party. The section commences at Connecticut 



River and passes west through the Railroad station. The .^ 



old river bed on its west part was formerly probably occu- 

 pied by White River, which then entered Connecticut River 

 a little below the present junction. The composition of the 

 highest terrace is well shown, for the bank is so steep that 

 nothing can grow there, a'nd the explorer finds to his sorrow, 

 especially if he wears shoes, that sand is plenty even at 200 , 

 feet above the present level of the river. section
