Weston's mill is reported in the census with 20 stamps. The same source gives the aggregate number of stamps of the Union Milling and Mining Company as 146, while in the above list only 90 are enumerated. Birdsale & Co.'s mill, as far as I am informed, has no stamps, but 40 pans working tailings. § According to the census report the mill of the Rigby Company has 5 stamps. The same report has the following mills, which I cannot identify in the above list: Cambridge Company, 20 stamps: Mammoth Company, 10 stamps; Utica & Herkimer, 5 stamps; Northumberland, 10 stamps; and Old Dominion, 10 stamps.

The number of stamps of the Brunswick mill is given by the census as 20.
Remodeled 1870.

It is impossible to reconcile the list with that furnished by the census. According to the latter the following mills are here omitted: Proctor, Jennings, Bassett's, Parks & Bowie's, Evan's-all tailing mills; and Gould & Curry, 80 stamps; Ogden, 15; Flowery, 18; Nevada, 21; Bassett's, 18; Empire State, 15; Occidental, 30 stamps. According to the same source the Succor has 15; the Empire, 16; the Hoosier State, 15; the Atlas, 18; Bay State, 18 stamps. On the other hand several mills which appear in the above list are not contained in the census, or cannot be identified.

JACKSON COUNTY.

Gold. Lacock & Co.

*The census reports Ruckels's mill to have 12 stamps, and unless the number of stamps has been decreased since 1869, when I visited the locality, this is the correct number.

According to the census the Prairie Diggings mill has now 10 stamps; the same authority mentions another mill in this county, which must have been erected during 1870, viz, that of the John Day Company, 8 stamps.

When I visited the county in 1869, Hopkins's and Jewett's mills were both altered into saw-mills. (See last report, page 216.)

*According to the statement of Mr. P. S. Buckminster, who visited this district for me in the latter part of 1869, the Victor mill had only 12 stamps and was standing idle.

The Monarch mill, with one French burr, one cast-iron grinder, two Varney pans, one settler, and one roasting furnace, is omitted here.
