��IVac/msett Mojmtain and Princeton.

��In a hilly country such as this is, springs and brooks of course abound. The height of land upon which Prince- ton is situated is a watershed between the Connecticut and Merrimack Rivers, and of the three beautiful brooks hav- ing their source in the township, one, Wachusett Brook, runs into Ware River, and thence to the Connecticut, while the other two, East Wachusett and Keyes Brooks, get to the Merri- mack by Still River and the Nashua.

Mention has been made of AVachu- sett Lake. Properly speaking, this cannot perhaps be considered as being in Princeton, inasmuch as about four fifths of its surface lie in the adjoining township of Westminster. Besides Wachusett Lake there is another called Quinnepoxet, which lies in the south- western part of the township, a small portion of it being in Holden. It is smaller than its northern neighbor, covering only about seventy acres, but it is a very charming sheet of water.

A brief account of the geology of this region may perhaps prove interest- ing. In the eastern portion of Prince- ton the underlying rock is a kind of micaceous schist, and in the western is granitic gneiss. The gneiss abounds in sulphuret of iron, and for this reason is peculiarly liable to undergo disintegra- tion ; hence the excellent character of the soil in this portion of Worcester County where naked rock is seldom seen in place, except in case of the summits of the hills scattered here and there ; and these summits are rounded, and show the effects of weathering. As we go westerly upon this gneiss range, and get into the hmits of Frank- lin and Hampshire Counties, a larger amount of naked rock appears, the hills are more craggy and precipitous, and

��in general the soil is poorer. The three principal elevations in Princeton are mainly composed of gneiss. This variety of rock is identical with granite in its composition, the distinctive point between the two being that gneiss has lines of stratification while granite has none. The rock of which Wachusett is mainly composed has rather obscure stratification, and hence may be called granitic gneiss. What stratification there is does not show the irregularity that one would suppose would result from the elevation of the mountain to so great a height above the surrounding country ; on the other hand the rock does not differ essentially in hardness from that in the regions below, and hence the theory that all the adjacent land was once as high as the summit of the mountain, and was subsequently worn away by the action of water and weather, is hardly tenable. The gneiss of this region is not especially rich in other mineral contents. Some fine specimens of mica have however been obtained from the summit of Wachu- sett. The only other extraneous min- eral found there to any great extent is the sulphuret of iron before mentioned. The common name of this mineral is iron pyrites, and being of a yellow color has in many localities in New England, in times past, caused a vast waste of time and money in a vain search for gold. It does not appear that the inhabitants of Princeton were ever thus deceived, though Whitney wrote in 1 793 : " Perhaps its bowels may contain very valuable hid treasure, which in some future period may be descried." In describing the summit of the mountain he speaks of it as " a flat rock, or ledge of rocks for some rods round ; and there is a small pond of
