water over it. Total length of bar from inside 8-feet curve to same outside, about 2,400 feet.

The 6-feet curve widens out inside the creek to about 400 feet, and extends to the bridge, uarrowing gradually until at the bridge it is only 110 feet wide. There are several bad lumps in this 6-feet channel, the water on them ranging from 4 to 5 feet. The shores of the creek are low and flat.

The mean range of the tide is about 14 feet. The estimate submitted contemplates dredging a channel, 100 feet wide, at such points as may be necessary, below the bridge, to give a depth of 7 feet at mean lowwater. To do so will require the removal of 29,000 cubic yards of material, at a cost of $7,250. Very respectfully, your obedient servant,

EXAMINATION OF CHANNEL LEADING INTO CABIN CREEK, MARYLAND.

UNITED .

Baltimore, Md., February 17, 1880. GENERAL: The river and harbor act of 1879 contained directions for an examination or survey of the channel leading into Cabin Creek, Maryland. An examination was made in September, 1879, by Mr. John L. Seager, assistant engineer.

This creek is in Dorchester County, Maryland. It is a short stream, entering the Choptank River only about 2 miles above the mouth of Secretary Creek, to which it is nearly parallel. Its headwaters are not far from the West Branch of the Nanticoke River. There is no difficulty in carrying 9 or 10 feet at mean low-water in the Choptank to the mouth of Cabin Creek, and generally there is almost everywhere in the river much more water.

The shipping business on Cabin Creek is chiefly done at a wharf about 1,500 feet from the mouth. The business, however, is not large, the produce of the country south of it and about the head of the creek (grain and fruit) going mostly to Secretary Creek, which is so near. Two lines of steamers enter Cabin Creek as high as the wharf mentioned above, connecting it with Baltimore and the landings on the Choptank River. There is a large hotel at the wharf, intended, I am told, for a summer resort. A town has also been laid out there, but no build gs had been erected last September.

Some potter's clay has been discovered near, and it is stated that a pottery will be erected this year.

The "xamination was made from the wharf to deep water outside the mouth, a distance of 3,500 feet. There is a channel with about 5 or 6 feet at mean low-water, 150 feet wide, to within 400 feet of the wharf, then it narrows to 80 feet and extends about 100 feet above the whart. The average rise of the tide is about 14 feet.

As far as could be learned, the navigation seems to be sufficient for present needs, and no estimate is submitted for the improvement of this creek. The map in the office will enable an estimate to be made, if required, at any time. Very respectfully, your obedient servant,

EXAMINATION OF CHINCOTEAGUE INLET, VIRGINIA.

UNITED STATES ENGINEER OFFICE,

Baltimore, Md., February 13, 1880. GENERAL: A survey or examination of "Chincoteague Inlet" was directed by Congress in the river and harbor act of 1879.

Through the agency of the representative from the district containing the locality, the Hon. Mr. Beale, of Virginia, an amendment of this item was agreed to by the lower house so as to read, "the channel from the wharf at Franklin to the island of Chincoteague.”

.” Although this amendment was not incorporated into the bill as finally adopted, I was reliably informed that it indicated what was really desired by those interested in the survey, and the field-work was regulated accordingly. The survey was made by Assistant Seager and party in November, 1879.

The area examined is between the wharves at Franklin and Chinco teague Island. These loaclities are both in Accomac County, Virginia. The former is the terminus of the Worcester Railway, by which it is connected with the Eastern Shore system, and then with Baltimore, Philadelphia, and New York. From Franklin to Chincoteague Island connection is kept up by a small steamer owned by the Old Dominion Steamship Company.

Franklin is a small place. There are a hotel, a store, and post-office there. About of a mile to the southwest of Franklin, on the bay store, is another small town called Greenbackville, with about 300 inhabitants. As is well known, Accomac County is extremely productive of sweet potatoes of fine quality, which are in great demand in the markets of the large Northern cities.

Chincoteague Island is about 84 miles long and of a mile in average width. It is quite low. It lies between Assateague Island and the main-land, being quite near the former. The population on the island is said to be 3,000 or 3,500, almost entirely dependent on the business in oysters, which are very abundent thereabout. There is a small settle ment on the northwest side of the island where most of the business is done. At this place there are a large hotel and several small stores, as also a custom-house. The following is the enrollment of vessels at this point:

No. Permanent enrollment, sail-vessels...

14 Licenses, under 20 tons, sail-vessels....

124 Licenses, under 20 tons, steam-vessels ...

1 Total....

139 The vessels are classed as follows: sloops, 107; schooners, 31; steamer, 1. The annual value of mercantile business, about $60,000. Amount of exports, $120,000—almost entirely oysters and clams.

The distance from the wharf at Franklin to the wharf at Chincoteague is very nearly 5 miles. The average rise of the tide is a little less than 2 feet. The following description of the channel is taken from Mr. Seager's notes:

At the wharf at Chincoteague the channel passes between the island and a broken marsh to the northwest, being about 600 feet wide. The width between the s-feet curves, at mean low-water, is 350 feet, the deepest water in mid-channel being:80 feel At 1,600 feet from the principal wharf the channel turns nearly at a right angle to the left and enters Chincoteague Bay. The S-feet curve runs out about 4,300 feet farther; thence, the water shoals to 44 feet in a distance of about 1,500 feet; thence, there are not less than 4 feet at mean low-water to within 1,600 feet of the wharf at Franklin, where the depth is about 31 feet.

The estimates below are for the excavation of a channel by dredging to a width of 200 feet, and depths respectively of 6, 7, and 8 feet at mean low-water. 6-feet channel, 245,000 cubic yards

$61,250 7-feet channel, 390,000 cubic yards

97,500 8-feet channel, 575,000 cubic yards

143, 750 As the currents sweep in some places across the line of the channel, the permanence of improvement by dredging alone is doubtful. If dikes and breakwaters are found to be necessary, the expense of a permanent improvement would be greatly increased. Estimates for such works are not now submitted, as the data for them are insufficient.

I have been told that while this dredging is greatly desired by those whose interests are connected with the navigation and matters to be benefited by its improvement, those who own and work the extensive and very productive and valuable oyster-beds are very much opposed to any change which would disturb them. Very respectfully, your obedient servant,
