MILL, estates. Mills are so very different and various, that it is not easy to give a definition of the term. They are used for the purpose of grinding and pulverising grain and other matters, to extract the juices of vegetables, to make various articles of manufacture. They take their names from the uses to which they are employed, hence we have paper-mills, fulling-mills, iron-mills, oil-mills, saw-mills, &c. In another respect their kinds are various; they are either fixed to the freehold or not. Those which are a part of the freehold, are either watermills, wind-mills, steam-mills, &c.; those which are not so fixed, are hand-mills, and are merely personal property. Those which are fixed, and make a part of the freehold, are buildings with machinery calculated to obtain the object proposed in their erection.

2. It has been held that the grant of a mill; and its appurtenances, even without the land, carries the whole right of water enjoyed by the grantor, as necessary to its use, and as a necessary incident. Cro. Jac. 121, And a devise of a mill carries the land used with it, and the right to use the water. 1 Serg. & Rawle, 169; and see 5 Serg. & Rawle, 107; 2 Caine's Ca. 87; 10 Serg. & Rawle, 63; 1 Penna. R. 402; 3 N. H. Rep. 190; 6 Greenl. R. 436; Id. 154; 7 Mass. Rep. 6; 5 Shepl. 281.

3. A mill means not merely the building, in which the business is carried on, but includes the site, the dam, and other things annexed to the freehold, necessary for its beneficial enjoyment. 3 Mass R. 280. See Vide 6 Greenl. R. 436.

4. Whether manufacturing machinery will pass under the grant of a mill must depend mainly on the circumstances of each case. 5 Eng. C. L. R. 168; S. C. 1 Brod. & Bing. 506. In England the law appears not to be settled. 1 Bell's Com. 754, note 4, 5th ed. In this note are given the opinions of Sir Samuel Romily and Mr. Leech, on a question whether a mortgage of a piece of land on which a mill was erected, would operate as a mortgage of the machinery. Sir Samuel was clearly of opinion that such a mortgage would bind the machinery, and Mr. Leech was of a directly opposite opinion.

5. The American law on this subject, appears not to be entirely fixed. 1 Hill. Ab. 16; 1 Bailey's R. 540; 3 Kent, Com. 440; see Amos & Fer., on Fixt., 188, et seq.; 1 Atk. 165; 1 Ves. 348; Sugd. Vend. 30; 6 John. 5; 10 Serg. & Rawle, 63; 2 Watts & Serg. 116; 6 Greenl. 157; 20 Wend. 636; 1 H. Bl. 259, note; 17 S. & R. 415; 10 Amer. Jur. 58; 1 Misso. R. 620; 3 Mason, 464; 2 Watts & S. 390. Vide 15 Vin. Ab. 398; Dane's Ab. Index, h. t. 6 Cowen, 677.

MILL, money. An imaginary money, of which ten are equal to one cent, one hundred equal to a dime, and one thousand equal to a dollar. There is no coin of this denomination. Vide Coin; Money.
