COLLECTOR'S OFFICE, San Francisco, Nopember 30, 1849,

Coast SURVEY OFFICE,

Washington, March 16, 1849. DEAR SIR: Under date of August 17, 1518, I received from the Secre. tary of the Treasury the letter of which the following is a copy:

TREASURY DEPARTMENT, August 17, 1849. Sir: Enclosed you will find a bill, passed during the last session of Congress, extending the laws of the United States over the Territory of Oregon, to which I invite your attention, with a view to the commencement of a survey of the coast of the United States on the Pacific. Very respectfully, your obedient servant,

R. J. WALKER,

S cretary of the Treasury. Prof. A. D. BACHE,

Superintendent U. S. C. S. In conference with the Secretary of the Treasury, the plans for commencing the survey were submitted, and I received oral directions to mature them, and to take the preparatory steps. These executed, I communicated with the department on the 21st October, and received the following reply:

TREASURY DEPARTMENT, October 23, 1848. Sir: Your letter of the 21st instant, communicating the execution of my oral instructions of August last, is received, and the arrangements which you have made approved. The department also approves of the following recommendations:

1. The detail of assistant Jas. S. Williams and sub-assistant Geo. Da. vidson for section X of the coast survey, to commence such work as may be designated in the instructions of the superintendent, and the furnishing of the parties with all instruments needful to the work. 2. The employment of such aids and such hands in the

parties as may be necessary, and the allowance of the requisite outfits. The persons to receive the pay and allowances fixed by the department for the Gulf of Mexico, or as inay be necessary and usual on the western coast to secure goed hands, and as may be approved by the superintendent. The officers to receive the allowances which apply to the sections on the Gulf of Mexico.

3. The general disbursing agent of coast survey is authorized to aj. vance for the expenses and pay of this party, up to July 1, 1949, a sum not to exceed eight thousand dollars, which sum he shall receive from the treasury in addition to the usual advance.

4. The organization of a hydrographical party, under the command of Lieutenant W. P. McArthur, United States navy, assistant in the coast survey, to accompany, or to follow as soon as practicable, the land party.

A copy of a letter relating to light-houses, beacons, buoys, &c., on the western coast, from the Fifth Auditor, is herewith transmitted.

The department requests that you will further the views of that officer, as far as practicable, by directing immediately such surveys as may be necessary for placing buoys and beacons, or locating light houses, as may not interfere with the general plan of the work-reporting the results to

[ocr errors]

this department; and that you will report, as early as convenient, in regard to the location of light houses, buoys, &c., at the entrance of Columbia river, referred to in section 27 of the law to establish a territorial government in Oregon. The accounts for necessary expenditures in the execution of this duty will be rendered to and paid by the collector at Astoria, who will be the superintendent of lights for the district of Oregon. (Note.-Subsequently modified, as far as relates to light-houses at entrance to Columbia river.)

Instructions will be given to the commander of the revenue brig Lawrence to furnish such facilities to the persons and parties of the coast survey, by the use of the vessel, boats, or crew, as may not seriously interfere with the revenue duties. The revenue cutter Ewing will be loaned to the coast survey, to be temporarily replaced by one of the coast survey vessels, until the alterations directed in the schooner Polk have been completed. Directions will be immediately given for the transfer of that vessel to such person as you may designate.

The department favorably considers your suggestion in regard to the land surveys, and proposes to act upon it, at a later date.

The department has communicated with the War and Navy Depart. ments in reference to the arrangements for the survey of the western coast, and has offered to carry out any suggestions which may be made not interfering with the general design of the coast survey.

Should further instructions be necessary, in consequence of any suggestions which may be made, you will be duly advised of them. Very respectfully, your obedient servant,

R. J. WALKER,

Secretary of the Treasury. Prof. A. D. BACHE,

Superintendent U. S. Coast Survey, Washington, D. C.

The whole of the arrangements for the execution of the work have been carried out. Yours, respectfully and truly,

A. D. BACHE. Hon. McCLINTOCK Youxg.

UNKONOONUC STATION, NEAR MANCHESTER, N. H.,

August 28, 1948- September 22, 1848. SIR: Having received oral directions from the Secretary of the Treas. uiry to commence the survey of the coast of the United States on the Pacific by the survey of Oregon, section X, you will make all the necessary preparations to set out as early as transportation can be procured and the instruments collected, and other arrangements can be made.

It is desirable as a preparation:

1. That you repair to West Point and assist Captain T. J. Lee, United States topographical engineers, assistant in the coast survey, in the astronomical observations in which he is engaged, so as to become versed in the practice and renew the theory.

2. That you proceed to the station of my party at Unkonoonuc, N. H., which I will make an astronomical and magnetic station, and where twin instruments to those which you will take for astronomical purposes to Oregon will be mounted. You will there obtain practice with these instruments, and provide yourself with memoranda on all points relating to their use and computation of results. (If there is time, magnetic ob. servations here—dir, variation, intensity.)

3. That you proceed to the office, to collect there, or on your way, the equipage, instruments, books, &c., which you will need, and obtain forms for computing the geodetic, astronomical, magnetic, and other results used by the parties of the survey; and with Captain Humphreys go over the computations of the geodetic work.

4. To proceed to South Carolina, to turn over the work in section V to the assistant who may be appointed to take charge of it, and to give him any information necessary to begin.

5. That you proceed io Bodie's island, in North Carolina, and remain some days with me, assisting in measuring the base there. The time for this will be about November 20.

6. That in Washington you provide yourself, from assistant S. C. Walker, with the blank forms for computing occultations and moon culminations, and practise in the reductions which they indicate.

7. This will leave the review of no part of the land work, of which you have not had recent practice, unmade, except the magnetic observa. tions.

I expect you to attend personally to the execution of all directions which I may give to others for your preparations; to send as much of the eqnipage and part of the instruments as can be prepared by the steamer Massachusetts, under charge of a careful hand, and the rest in the following month-November-by the mail steamer, or otherwise, as may be

found expedient, under special charge of a trusty hand; to proceed yourself, with the assistants of your party, to Chagres, and overland thence in time to meet the instruments, &c., at Panama, and to proceed with them to Oregon.

1. Equipage.-You are authorized to order five wall tents and an instrument tent of suitable dimensions, and with tarpaulins, from Fenton of Philadelphia. They should be soaked in a weak solution of corrosive sublimate, and thoroughly dried before packing-the tarpaulins to be made very dry-the whole to be packed, marked, and numbered under your personal direction. Of the soldiers' tents belonging to the survey at Fenton's, you are authorized to take two. The copper bands, &c., for the tent-poles should be taken. Tool chest and tools, (carpenter's,) carpenter's levels, mess furniture for men and aids, who receive their board from the survey; stoves, &c., for cooking, &c.; portable tables and camp stools. Equipage connected with transportation will have to be obtained in the country. The mechanics whom Captain Alexander V. Fraser takes out in connexion with the revenue marine may, no doubt, be available for work of this sort.

Stationery.-Ordinary supplies of writing and drawing materials, and all blank forms used in the coast survey; lithographed tables, con. for barometer, printed regulations, copy of superintendent's reports, all printed instructions, forms of reports, forms of accounts, maps of Atlantic coast of coast survey, as specimens, &c.; books for recording geodetic, astronomical, transit, latitudes, culminations, occultations, magnetic observations, miscellanea, duplicates, &c.; tin cases for maps. You will make your own rules about the amount of baggage to be allowed to your assistant, aid, and men. I will endeavor to have the wages put on the footing of those of the gulf coast, but, as contingencies may be extraordinary, will make every allowance possible for them.

Books.-Pearson's Astronomy, (not indispensable;) Francœur's Astr. Pratique; Francœur's Geodesie; Bailey's Tables and Formula; Simms on Transit Instruments; Trans. Am. Phil. Society, vol. 2, new series, (for Mr. Hassler's paper on Zenith Telescope;) Callet's or Bajuet's Logarithms; Bowditch's Useful Tables, or Bowditch's Navigator; Galbraith's Mathematical and Astronomical Tables; De Mafra's California and Oregon; British Nautical Almanac, as far ahead as published; American Almanac, 1849; Downe's Tables, if out. Such other books, bearing directly on the work, as you may deem advisable to purchase. Examine a set of Vancouver's charts at Blunt's, and, if you deem it advisable, purchase. Any charts of Pacific coast which may be obtained at a reasonable cost, purchase. I have written for the British admiralty charts, and will again try, through a private source, to obtain the published results of all the British surveys. Wilkes's Narratives and Charts; letters in Intelligencer from longitude discussions with Frémont; transit results.

Instruments, geodetic.-Base apparatus; duplicate set of base bars in office to be cleaned, remeasured, and carefully packed-four two metre bars in the set; clamps to attach them to each other; sector for inclination of apparatus; eight thermometers; rough level; heavy plumb bobs, carefully centred; two small plumb bobs, well centred; microscopes, at least five, with stands; friction rollers on which bars move; large iron screws for trestles, (New York or Philadelphia;) rough levels for trestles, small and large, (office;) small transit for alignment of base. The wooden rod for support
