    • Leveling The act or operation of making level.
    • Leveling (Surveying) The art or operation of using a leveling instrument for finding a horizontal line, for ascertaining the differences of level between different points of the earth's surface included in a survey, for establishing grades, etc., as in finding the descent of a river, or locating a line of railroad.

  • Interesting fact: Death Valley, California, has a point that is 280 feet below sea level.
    • n leveling The act or process of reducing an uneven surface to a level or plane.
    • n leveling The art or operation of ascertaining the different elevations of objects on the surface of the earth; the art or practice of finding how much any assigned point on the earth's surface included in a survey is higher or lower than another assigned point. It is a branch of surveying of great importance in making roads, determining the proper lines for railways, conducting water, draining low grounds, rendering rivers navigable, forming canals, and the like. The instruments commonly employed are a level or leveling-instrument and a pair of leveling-staffs. One of the staffs is held up vertically, resting upon the ground at the initial point. The observer then goes forward with his instrument for a convenient distance, makes his telescope level, and directs the rod-man to raise or lower the target until it is at the height of the telescope. This is called a backsight. The height of the target on the rod is now read. The other rod has meantime been carried forward, and is observed in the same manner. This is called a fore-sight. The instrument is now carried forward and a back-sight is made on the last rod. When a bench-mark or other terminus is reached, all the fore-sights are added together, as well as all the back-sights, and the difference of the sums is the difference of elevation.

Springs the whip! and again we are level.

Singing an ecstasy I could not share,
Played cunning in my thoughts. Surely in these
Pleasures there could not be a pain to bear
Or any discord shake the level breeze.

Not on the vulgar mass

The low world laid its hand,
Found straightway to its mind, could value in a trice:

And "public feeling" make short work,—

The stately oak is levelled and all its strength laid low;
So fell that tower of manhood, undaunted, patient, strong,
White with the gathering snowflakes, who faced the storm so long.

An important fact is that these hypercubes, where the walk is trapped, are not level sets for the potential neither for the reversible measure denoted π , however they can be partitioned in level sets for π . A part of this work is devoted to the study of the local time of the walk on these level sets.
