Report of progress made in survey at Reedy island during the year ending June 30, 1867.

This survey was commenced by R. M. Bache, Assistant United States Coast Survey, on the 1st of May, 1867. The stormy, rainy weather prevalent during the months of May and June interfered with its progress greatly. At the close of the fiscal year, on June 30, 1867, the field-work had not been completed.

It will be some time before the results of the survey can be ascertained and be made available to determine what plan shall be adopted and the expenditures necessary under such plan.

The expenditure on the survey on June 30, 1867, had been as follows, viz: Services of hired men.

APPENDIX M.

NEW YORK, August 6, 1867. GENERAL: I have the honor to submit the following report of operations upon the improvement of the Hudson river during the year ending June 30, 1867: By letter of August 6, 1866, the department was furnished with a report of the condition of the Hudson river, and of the works erected, for its improvement by the United States engineers and by the State commissioners, from Troy to New Baltimore.

The works erected by the United States from 1834 to 1843, consisting of the Overslaugh dike below, and the Port Schuyler dike above, Albany, were found to need extensive repairs, and to this purpose it was proposed to devote the whole sum of $83,000 then available. Brevet Lieutenant Colonel John M. Wilson, captain of engineers, having reported to me September 6, as assistant upon the improvement of the Hudson river, repaired to Albany, furnished with the necessary instructions to undertake the repairs of the United States dikes above and below Albany. Under his efficient supervision repairs have been vigorously pushed during the year.

Notwithstanding the lateness of the season at which work was commenced, and the unusual number of freshets which postponed active operations of this season nearly to June, considerable progress has been made.

The repairs of the dikes consisted in repaving slopes with large stone laid by hand, in restoring the original cross-section of the dike by a filling of stone, and by repaving the surface; and when the destruction of the dike had gone too far, in rebuilding it, using the construction known as the half-dike.

November 9, 1866, a full report and estimates for the improvement of the Hudson river, made as complete as possible from information compiled from former surveys and reports, was rendered to the department.

Under this report a further appropriation of $305,188 was granted by Congress. A board of engineers was convened at Albany on May 14, 1867, and the system described in the report of November 9 substantially indorsed.

A survey of the river near New Baltimore, and also at Cuyler's island, above Albany, was made in May and June, for the express object of locating correctly the works of improvement required at those localities. These surveys will hereafter form portions of the general survey of the river.

Tide-gauges have been set at Troy, Castleton, Albany, and New Baltimore, and temporarily, for specific objects, at Coeyman's, Bogart's island, and Cuyler's island. The extension of the freshet into the month of June has prevented, for want of sufficient length of observation from the cause above assigned, a report of the tidal state of the river for the last year.

Current observations, giving velocities of surface and the set, have been made at Coeyman's, and the results transmitted, in a sketch of Barren island and the neighborhood, to the department. The surveys and examinations described have not sufficiently advanced as yet to have particular bearing upon the system of improvement adopted.

These surveys will continue until all necessary information has been obtained. Money statement.-Appropriation of 1864.-Repairs of harbors on the Atlantic

Information supplied to conform to the acts of Congress making appropriations for this work:

1. Resurvey has not sufficiently progressed to furnish results.

2. There is required to be appropriated to finish the scheme of improvement, according to the estimate of November 9, 1866, the sum of $474,109 75.

3. The amount that can be profitably expended during the next fiscal year is $335,000.

4. This work is situated in the fourteenth collection district.

5. The nearest port of entry is Albany, New York.

6. The amount of revenue collected there for the last fiscal year is $19,974. 7. The amount of commerce and navigation to be benefited by this work is about $500,000,000.

8. Abstract of proposals, with names of bidders sent herewith.

9. Abstract of contracts, with names of contractors sent herewith. 10. Abstract of contracts for each class of materials or labor. No. 9.)

(Included in

The works to be finished this year are the repairs of the United States dikes, new dike at Cuyler's island, and cutting away the face of Mull's island, with a probable total expenditure of $162,960.

During the next season the long dikes at Castleton, long dike between Lower and Upper Patroon's island, long dike connecting Bogart's island with Westerloo island, the dike from Base island to eastern bank of river, and dredging, will be the probable operations.

For these essential operations there would be required $335,000, and deducting therefrom the balance of the present appropriations, there would be left in round numbers the sum of $152,000, which is asked to be appropriated for the fiscal year ending July 1, 1869.
