Common of estovers is either appurtenant, i. e. annexed to land, or in gross, i. e. existing independently of land. Elt. Com. 82, where it is shown that there is no such thing as common of estovers appendant. Cooke Incl. 34. See supra 28 6, 9; and APPURTENANT; IN GROSS. 12. Another species of common, often included under common of estovers, is the right to take for use on the commoner's tenement part of the wild herbage and brushwood (such as heath, furze, broom, fern, rushes, and, in some manors, hay) from the land of another. Elt. Com. 117. 13. Common of turbary. -Common of turbary in its modern sense is the right of taking peat or turf from the waste land of another, for fuel in the commoner's house. (2 Bl. Com. 35; Wms. Com. 187.) It appears that formerly a distinction was drawn between peats (turbe) from a peat-moss or boggy ground, and "flags" (French bléches, Latin blestia) or turfs pared from the surface, and that strictly speaking, common of turbary does not give a right to take "flags," that being destructive of the pasture. (Elt. Com. 96.) The right is, however, unimportant at the present day; it is analogous to common of estovers, and is therefore either appurtenant or in gross, but not appendant. Id. 99. 14. Common of piscary.-As to common of piscary, see FISHERY. 15. Common of digging. -Common of digging or common in the soil, is the right to take for one's own use part of the soil or minerals in another's land; the most usual subjects of the right are sand, gravel, stones, and clay. It is of a very similar nature to common of estovers and of turbary. Elt. Com. 109. Supra 11, 13; and see DOLE; TINBOUNDING. 16. Common of fowling.-In some parts of the country a right of taking wild animals (such as conies or wildfowl) from the land of wildfowl, it is called a "common of fowling." (Elt. Com. 118.) As to apportionment of commons, see APPORTION, § 5. See, also, LEVANCY AND COUCHANCY; PAWNAGE; SANS NOMBRE; - From the OLD FRENCH: estevoir, or estovoir, that which is necessary. Loysel, Inst. gl; Termes de la Ley. Every tenant for life or years of freehold land, unless restrained by agreement, may of common right take upon the land a reasonable quantity of wood for fuel, repairs, &c. This is called "estovers," or "botes," which are sometimes divided into house-bote, for fuel and repairs of the house, plough-bote, for making and repairing instruments of husbandry, and hay-bote, for repairing fences. (Co. Litt. 41 b; Britt. 153.) Copyholders' rights of estovers are sometimes subject for paying the increased amount, because to customary restrictions. (Elt. Copyh. 209.) he is estopped by his own negligence. As to common of estovers, see COMMON, § 11. Guardians of Halifax v. Wheelwright, L. R. 10 Ex. 183; Arnold v. Cheque Bank, 1 C. P. D. 578; Baxendale v. Bennett, 3 Q. B. D. 525. See McKenzie v. British Linen Co., 6 App. Cas. 82. 6. Equitable estoppel, or estoppel by acquiescence, occurs where a person by tacitly representing his own position to be more favorable to another person than it really is, has induced that other to alter his position on the faith of the representation being true. Thus, if a stranger begins to build on land, supposing it to be his own, and the real owner, perceiving his mistake, abstains from setting him right, and leaves him to persevere in his error, the court will not afterwards allow the real owner to assert his title to the land.
