The general character of the soil is good. A narrow valley extends the entire length of the town, from north to south, diversified by rich meadow-land, ridges of sand, and rocky out-croppings. East and west of this valley are ranges of hills, running north and south, possessing a productive soil, suitable for grazing and tillage. East or Grout's Hill, formerly called King's Hill, lies in the northeastern section of the town, and is a landmark of great interest.¹ South of it is Moulton Hill. West of Moulton Hill lies Cedar Swamp Mountain. Chicopee, or West Hill, is the principal elevation in the west part of the town, while Bald Peak, its northern extremity, Packard Mountain on the south, and Black Rock and Moose Mountain on the western border, stand as sentinels guarding the approaches to the town.

Chicopee Brook flows through the centre of the valley, having its rise near the Stafford line, and flowing northward to the Chicopee River. Its water-power is extensively used for manufacturing purposes. Other streams traverse the eastern and western sections of the town. Twelve-Mile Brook is a stream of some importance in the northwestern part, while minor streams are found in various localities.

¹ The first town-plat of Brimfield was laid out on this hill.
