The water of the Westfield, Mass., river is somewhat better than that of the Connecticut river without filtration: but the latter, as compared with that of the Nashua river above Clinton (the principal two best sources of supply of the metropolitan district) is of considerably better quality although its hardness somewhat exceeds that of the former.

The new dam at Holyoke, Mass., for which bids are soon to be asked, will be 700 feet long and thirtyfive feet deep at the deepest part. It will be built of earth, with a masonry core ten feet deep at the bottom and two feet at the top. The dam will slope from the top toward the basin, and also from the basin, and will take some 20,000 cubic yards of earth and 2,000 cubic yards of masonry. The dam will hold back some 300,000,000 gallons, covering sixty acres. The basin has been about half prepared, and work has been begun in preparing the rest, part of that which is being removed being used in the formation of the dam.

Holyoke, Mass., has a water supply sufficient for many years, and the revenue from water is being used in part to pay the running expenses of the city. The reservoirs are the Ashley, capacity, 800,000,000 gallons; the Whiting street, 500.000.000 gallons; and the Fomer, 17.000.000 gallons—total, 1,317,000.000 gallons. In addition work has been begun on a high-service reservoir of 300,000.000 gallons, and the Fomer watershed will allow, with comparatively little expense, of the construction of two storage reservoirs, with capacity of 1.500,000,000 gallons—making the total prospective capacity of the Holyoke reservoirs 3.100,000.000 gallons. The present consumption is estimated at 6,000,000 gallons a day.

Chicopee, Mass., has as its source of supply the Cooley brook and its tributary, the Morton brook, which flow northerly from the Chicopee river and empty into it a little less than a mile above the dam at the falls. The water is of excellent quality, and in fully adequate quantity, with no prospect of scarcity. The city recently assumed a bonded debt to extend this system to Williamansett, which previously had been supplied from a small separate reservoir. The water has to be pumped to give it sufficient pressure to reach all parts of the city and afford fire protection. If more than a certain quantity is taken, the city becomes liable to the manufacturing companies below for damages, but this limit is not likely to be reached soon. There is no dissatisfaction in the city with the present supply.
