The Ozark region is substantially a low dome, with local faulting and minor undulations, dominated by a ridge - or, more exactly, a relatively even belt of highland - that runs from near the Mississippi about Ste Genevieve county to Barry county on the Arkansas border; the contour levels falling with decided regularity in all directions below this crest.
When a field is ridged in the line of the greatest ascent of the ground, there is an obvious convenience in adopting the furrows as the site of the drains; but wherever this is not the case the drains must be laid off to suit the contour of the ground, irrespective of the furrows altogether.
The west central portion has considerable irregularities of contour, and the north-west is distinctively hilly.
These points lie, therefore, upon a horizontal plane at a given elevation passing through the land shown on the map, and the contour-line is the intersection of that horizontal plane with the surface of the ground.

With three component metals the complete diagram giving the variations in any property must be in three dimensions, although by the use of contour lines the essential facts can be represented in a plane diagram.
If the distance between the contour lines is h and the length of the individual contour lines 1, the sum of their lengths / (1), and A the area of the surface under investigation, then the mean angle of slope is obtained from the equation h?
Some of the " deeps " to which names have been given disappear or are divided into two or three smaller deeps when the contour lines representing hundreds of fathoms are translated into contour lines representing hundreds of metres.

I 1, F) so as to change the star-like contour into one more evenly circular, the tentacles grow out, and the various parts become complicated and take on the structure of the adult medusa.
The most famous is the first, which is doubly misnamed, since it is not a temple and its contour is too unsymmetrical to be described properly as elliptical.
An ill-balanced load also exaggerates " plunging," and if the period of oscillation of the load happens to agree with the changes of contour or other inequalities of the track vibrations of a dangerous character, giving rise to so-called " sinuous " motion, may occur.
Contour lines are at internals of "'?
Lines of induction drawn through every point in the contour of a small surface form a re-entrant tube bounded by lines of induction; such a tube is called a tube of induction.
Either to the simple lateral tail feathers with a few rami only, developed only on one side of the shaft and of uniform metallic coloration - or to the simple contour feathers of small size, with the usual symmetrical series of numerous rami right and left of the shaft and no remarkable colouring.
The one-sided specialization and the peculiar metallic colouring of the lateral tail feathers mark them as the extreme terms of a degenerative series, whilst the symmetry, likeness of constituent parts inter se, and absence of specialized pigment, as well as the fact that they differ little from any average feather of birds in general, mark the contour feather as primitively simple, and as the starting-point from which the highly elaborated eye-painted tail feather has gradually evolved.
The only true mountain systems, however, so far as known, are the two parallel ranges which follow the contour of the coast, and the central, or Goyana, system.
By r Soo yds.); on the western, southern and eastern faces the line of defence is almost straight, the only projecting points being the gateways, but on the northern face the contour is broken by a double outwork, consisting of the Ark or citadel, which is built of sundried brick on a high artificial mound within the enceinte, and a lower work at its foot, called the Ark-i-nao, or " new citadel," which extends ioo yds.
Modern orometry has introduced the calculation of the mean angle of the slope of a given uneven surface provided that maps can be prepared showing equidistant contour lines.
A similar change in the contour lines may result from the substitution of lines in fathoms for those originally drawn in metres, and hence it is extremely desirable that specific names should only be given to such features as are pronounced enough to appear on maps drawn with either unit.
The general contour of the upland, marked by a remarkably even sky-line, is evident at almost every locality in the state.
The surrounding hills are of considerable altitude, the most remarkable being the head of Ben A'an (1750 ft.) and the grassy craigs and broken contour of Ben Venue (2393 ft.).
Dismantled since 1816, and now largely converted into promenades, the fortifications give the city an irregular pentagonal contour, modified at the north-west corner by the addition of a citadel also pentagonal.
The contour of the sea-bed, however, has been shown to influence this distribution, the continuation of the slope of a steep shore beneath the sea being adverse to their formation, whereas on a gentler slope they may be formed.
Each suburb is laid out independently, with straight streets where the ground permits, and crooked ones where the shore-line or mountain contour compels.

He showed that an imaginary spheroidal shell, concentric with the earth and cutting the slope between the elevated and depressed areas at the contour-line of 1700 fathoms, would not only leave above it a volume of the crust equal to the volume of the hollow left below it, but would also divide the surface of the earth so that the area of the elevated region was equal to that of the depressed region.6 A similar observation was made almost simultaneously by Romieux, 7 who further speculated on the equilibrium between the weight of the elevated land mass and that of the total Areas of waters of the ocean, and deduced some interesting relathe cru st tions between them.
Sessions of Chicago in November 1887, covered a housing in combination with a vertical metallic plate frame of the general contour of the central passage-way, which projected slightly beyond the line of the couplings and was held out by horizontal springs top and bottom, being connected with the platform housing by flexible connexions at the top and sides and by sliding plates below.
The map of Italy, or other maps, in this work, on a similar method), and if this be combined with contour lines very satisfactory results can be achieved.
Given the area A of the plane between the two horizontal contours, the height h of the upper above the lower contour, the length of the upper contour 1, and the area of the face presented by the edge of the upper stratum l.h = A 1, the slope a is found to be tan a = h.l I (A - A i); hence its superficies, A = A2 sec a.
