At my request, Mr. Phillips, the diver, made an examination and took some measurements of this rock for the purpose of determining the cost of removing it. By this examination it was found that the rock stood 8 feet high from the bottom and measured 36 feet around it, making 29.2 cubic yards, or 58.4 gross tons weight, which can probably be removed for $5 per ton, or at the total cost of $292.

There are a number of smaller bowlders in the immediate vicinity of Bushworth Rock, but as they are covered by a sufficient depth of water (varying from 12 to 15 feet at mean low water), I consider their removal unnecessary at present, and have made no estimate for it.

ALLEN'S ROCK BEACON.

This beacon is situated near the mouth of the Warren River, a little to the south of a large rock at the southern extremity of Adams's Point, and directly opposite Jacob's Point. It is about 15 feet in height and is built of rubble masonry laid in cement mortar. The pier surrounding the beacon is composed of dry rubble masonry, rectangular in shape, 73.5 feet long by 39 feet wide, and is about 9 feet above mean low water. It was built in a depth of water varying from 7 to 12 feet on the north and west sides to 16 feet on the sides towards the channel, upon the west bank of which the beacon is placed.

Both the beacon and the pier are weather-beaten and dilapidated. Portions of the pier have been broken down from time to time by the ice and water washing over it, its height not being sufficient to prevent this overflow. This could be remedied by rebuilding a part of the pier and making the whole structure about 2 feet higher than at present. I should suggest that the corners be made rounding instead of square, as rounding corners would, in my opinion, be less liable to be damaged by the ice than angular corners.

According to your instructions I have made two approximate estimates for repairing the pier and protecting the beacon, as follows:

1. BUILDING UP THE PARTS BROKEN DOWN IN THE PIER TO THE ORIGINAL HEIGHT AND PROTECTING THE BEACON.

Taking down and rebuilding 43 cubic yards dry rubble masonry in the pier, at $3.50..

Furnishing and building in place 282 cubic yards rubble masonry in the pier, at $5.50.

$150 50

Taking down and rebuilding 14 cubic yards rubble masonry laid in cement mortar in the beacon, at $12.50 .

1,551 00

175 00

Total.......

1.876 50

2. REPAIRING THE PIER AND BUILDING THE WHOLE STRUCTURE TWO FEET HIGHER TO PREVENT THE ICE FROM WASHING OVER IT, ALSO PROTECTING THE BEACON. Taking down and rebuilding 43 cubic yards of dry rubble masonry in the pier, at $3.50.

Furnishing and building in place 495 cubic yards dry rubble masonry in the pier, at $5.50.

Taking down and rebuilding 14 cubic yards rubble masonry laid in cement mortar in the beacon, at $12.50 .

D 1.

IMPROVEMENT OF THE CONNECTICUT RIVER, MASSACHUSETTS AND CONNECTICUT.

This river, rising in New Hampshire, flows in a generally southern course, passing between the States of New Hampshire aud Vermont, and through the States of Massachusetts and Connecticut to Long Island Sound, into which it empties at Saybrook Point, Conn. It is naturally divided into two parts; Hartford, which is practically at the head of navigation, being the point of division, and appropriations for the improvement of the river, made by Congress, have been divided in the same way, the acts stating to which part of the river the money appropriated should be applied. The divisions are as follows: (1) Abore Hartford, Connecticut.-Embracing a length of about 66 miles from Hartford, Conn. to Miller's Falls, Mass.

(2) Below Hartford, Connecticut.-Embracing a length of about 50 miles from Hartford to the mouth of the river at Saybrook Point.

(1) ABOVE HARTFORD, CONNECTICUT.

Miller's Falls, Mass., is at the head of possible navigation of the Connecticut River. From this point down to Holyoke, a distance of about 32 miles, the river is susceptible of improvement; but it cannot be used on account of a dam crossing the river and falls at Hol yoke, which entirely obstructs navigation. The lockage required to lift boats from the lower to the upper levels at Holyoke is about 60 feet. From Holyoke to Enfield Falls, a distance of 18 miles, there is a fair channel from 4 to 5 feet deep at low water, which could easily be made 8 feet deep. Enfield Falls or ràpids cover a stretch of river about 5 miles long, having a fall of about 32 feet at low water. The bed here is rocky and very uneven, the slope not being uniform, but consisting of a succession of long, shallow reaches, separated from each other by rapids. From the foot of Enfield Falls to Hartford, a distance of 11 miles, the river has a broad, sandy bed, with a depth of 3 or 4 feet at low water. The improvements made by the United States Government in this section of the river have been confined to that part of it which lies between Hartford and the foot of Enfield Falls, under a project approved in 1871, "for giving an increased depth to the channel by the construction of wing-dams and by dredging." By various acts of Congress $100,000 have been appropriated for the improvement of this part of the river. Of this amount the following balances are yet unexpended, namely, from the appropriation of June 10, 1872, for improving the Connecticut River on or above Enfield Falls, $10,702.92, and from the appropriation of June 14, 1880, for "improving the Connecticut River between Hartford and Holyoke," $13,669.80; total, $24,372.72.

Under a charter granted by the State of Connecticut in May, 1824, the Connecticut River Company have constructed a canal with locks around Enfield Falls, which allows vessels to pass through.

The locks are 80 feet long and 18 feet wide.

The company collects tolls from passing boats, but the canal is chiefly used for water-power. A project for improving the channel and constructing a larger canal around Enfield Falls was submitted to the General Government in 1878 by the engineer officer in charge of the Connecticut River improvement. This project was amended in 1880. (See Annual Report of Chief of Engineers for 1881, page 566.) It provides
