The followmg Catalogue is intended to include, so far as known, the Flora 

 within about thirty miles radius of the town of Hanover, New Hampshire, a 

 circuit extending to and embracing the mountain peaks Moosilauke and 

 Kearsarge in New Hampshire, and Killington in Vermont. The outlying towns 

 intersected by the circumference of the circle, beginning with the southern 

 limit and the Connecticut river, are, in New Hampshire, Charlestown, Acworth, 

 Lempster, Goshen, Newbury, Sutton, Andover, Hill, New Hampton, Bristol, 

 Bridgewater, Plymouth, Campton, Ellsworth, Benton, and Haverhill. Con- 

 tinuing the circuit on the Vermont side of the river, the towns are Newbury, 

 Topsham, Orange, Williamstown, Brookfield, Braintree, Rochester, Pittsfield, 

 Chittenden, Mendon, Shrewsbury, Mt. Holly^ Ludlow, Chester, and Spring- 

 field. The region thus indicated is divided nearly equally between the two 

 adjoining states by their common boundary the Connecticut river, and includes 

 a variety of soil, climate, and location sufficient to furnish a home for a major- 

 ity of the plants of northern New England, except those peculiar to the sea- 

 shore and the higher mountains. 



The only river of any considerable size is the Connecticut, running from 

 north to south throughout the entire district, a distance of sixty miles or more. 

 Numerous tributaries join this river on both sides, the largest of which, in 

 Vermont, are the Ompompanoosuc which empties in Norwich, the White 

 river at White River Junction, the Ottoquechee in Hartland, afew miles from 

 whose mouth is the deep gorge known as " Quechee Gulf," and the Black 

 river in Springfield. In New Hampshire, the Mascoma, the outlet of Mascoma 

 Lake, joins the Connecticut in West Lebanon, and the Sugar river in Clare- 

 mont. The Pemigewasset and other streams which form the head waters of 

 the Merrimack river, moreover, reach some towns in the eastern part of the 

 district. 



The larger sheets of water included are, in New Hampshire, Sunapee 

 lake. Newfound lake, and Mascoma lake, or Enfield pond. Sunapee lake, 

 in the towns of Sunapee, Newbury, and New London, is about seven miles 

 long, and at one point two and one half miles broad, and is a well known 

 summer resort. Newfound lake in the towns of Hebron, Bridgewater, and 

 Bristol, is less known, but is a fine sheet of water, six miles perhaps in length, 

 and three miles in extreme breadth, and very nearly as large as Sunapee. 

 Mascoma lake or Enfield pond is somewhat smaller, being four and a half 

 miles long by rather more than half a mile in width. 



On the Vermont side there is little to correspond with the above. Fairlee 

 pond or Morey lake in the town of Fairlee, and Fau'lee lake, partly in the 

 same town, are both comparatively small. The purity of the water in these 

 larger lakes, and their commonly bold or gravelly shores, are not favorable to 

 the accumulation of much aquatic vegetation, but even here the botanist will
