Summary

The New International Encyclopædia…

A line of granites and diorites appears near the coast west of the Piscataqua, and through the centre of the State, running west of the Merrimac Vallev toward the White Mountains, there are extensive outcrops of porphyritic gneiss. The heart of the White Mountains themselves is composed mainly of granite. Few regions exhibit more well-marked evidences of glacial action than New Hampshire. The rocks are everywhere striated, and boulders of all sizes are scattered all over the State, even on the mountain summits.

The New International Encyclopædia…

A large portion of the surface of the State lies too broken for agriculture. Only along the coast and in the river valleys is the soil rich and well adapted for farming. Latterly it has been cheaper to import cereals than to grow them in New Hampshire. The number of farms and their total acreage were but slightly greater in 1900 than in 1850, but the area of the improved acreage decreased over one-half during the half-century, amounting in 1900 to only 29.8 per cent.

The New International Encyclopædia…

New Hampshire is relatively more rough and mountainous than the average State on the Atlantic slope. The easternmost extension of the Appalachian system traverses the State lengthwise, running first as a ridge along the western boundary on the east bank of the Connecticut River, and culminating in the rugged mass of monadnocks known as the White Mountains.
