Hobbs, 17 N. H. 524; easements in gross in respect to the flowage of water.41 Easements are also divided, with respect to the obligation imposed on the owner of the servient estate, into negative easements and affirmative easements. Under the former the owner of the servient estate is prohibited from doing some acts of ownership on his own property, as an easement that land shall not be built upon,42 while in the case of an affirmative easement the owner of the servient estate is merely required to permit something to be done on his land, such as piling materials on it43 Easements are also divided into natural and conventional. The former exist as the outgrowth of natural rights, and are necessary, as a matter of course, for the enjoyment of the dominant estate. Instances of natural easements are rights to support of land and to the flowage of water.44 Conventional easements, on the other hand, are those which are created by the agreements of the parties, and add rights to the dominant estate, which, though not strictly necessary, add to its enjoyment, such as rights of way or to light and air.45
223. The principal rights and incidents growing out of easements are the following:
(a) The dominant owner must use his easement, and the servient owner his estate, in a reasonable manner.
(b) The dominant owner must repair the easement.
(c) The servient owner must not obstruct the easement.

Use of the Easement.
The owner of the dominant estate must make his use of the easement reasonable, so as to interfere as little as possible with the servient owner's enjoyment of his land.46 On the other hand, the latter must not use his estate in such a way as to obstruct the easement or unreasonably interfere with its enjoyment.47 The grant of an easement includes a grant of all rights necessary for its use. But the use of an easement must be confined to the object for which it is granted.48
Repairs of the Easement.
In the absence of a contract providing otherwise, the owner of the dominant estate-that is, the one who has the benefit of the easement-must keep it in repair and condition for use.49 The easement carries with it the right to do anything necessary to make repairs.50
Obstruction of tlce Easement.
The owner of the dominant estate may have an action for the obstruction of his easement by the servient owner, though no actual damage has been caused.51 The owner of the dominant estate may
