ln AFigs. 2, 3 and al, one of the similar line-posts is represented, the crosssectional view (Fig. ll) illustrating the shane oit' the side of the line-post against which the v.'

y1reencing is secured, this side of the post he ing concave, as represented 13, to present a pair or' spaced bearing surfaces, or points, land l5, for engagement with the longitudinalwires ll which are firmly held against the surfaces 14. and l5 by any suitable nieans, as for example, staples 16, which embrace the horizontal wires l1 and pass through openings 17 in the post, at the rear side et which the endg of the staples are spread apart, as shown (Fig. 3), to irmly hold the fencing in position. .ln applying the staples i6, as stated, the Wires l1 are deflected slightly inward, thus drawing them. taut and gripping them firmly against the surfaces le and l5, which latter, together with the staples i6, afford threepoiiit contacts with the wires and thus serve to very irnily secure the fencesivires to the ln Fig. 5 is shown another forni of line post, wherein the principle of the post shown in F 2, 3 and l is carried out. ln this construction, the post, instead of being i. shape in cross section, of general l"lshape, the tace of the post against which the Wires ll. bear being concaved, as represented at i8, to provide spaced points 19 and 20, into hun contact with which the longitudinally extending wires of the :tencing are drawn, upon applying to position a staple 2l, which embraces the yi-rire l1 between the bearing surfaces 19 and v20, and extends at its ends through openings 22 in the post, and has its ends deflected against the rear side et the portion of the post in which the concave surface is provided.

lt Will be noted that in each of the forms of line-post described, the side of the post against which the Wires ll extend, is rein forced by the rearwardly extending liange of' the post, indicated at in 4, and 2d in Fig. 5. This feature et the construction presents advantages Whether the posts 9 are rigid or flexible, as stated above.

lt is manifest that a line-post must be so constructed that it will present the requisite strength for resisting the strains to which it is subjected in use, and thatit the ordinary torni of staple, which is relatively short, is to he'used, the recess between the spaced' bearing points on the posti against which the wire hears, must be relatively sha-lkw. By constructing the post With' a flange, such as the flange 23 or 24, which extends laterally cf the fencing, the post is so reinforced nitrates that the portion of the latter which extends at an angle to the said laterally extending flange, and against which the fencing hears, may be constructed with relatively shallow recess to afford the spaced hearing-surfaces for the Wires ll, 1aflnereas were these laterali 'tending flanges not provided, the post, in to aliord the relatively shallow recess for permitting ordinary staples 'to be used as the fencing-fastening' means, would be required to be so bulky in order to present the desired strength, that they would be iuiconimercial.

ldlhen the feature just descrihed is incorporated in a fiexiblepost, where the anche thereof are located belenY the le vel of the ground and resilient portions of the Vpost are likewise embedded in the ground,

a very decided advantage afforded over line-posts provided with fiat 'laces against which the fencing hears, due to the tact that by the engagement or the wires 1l with spaced bearing surfaces on the. 'post with the fastening device engaging the wires intermediate these bearing surfaces, the Wires ll are rinly held to the post and in such manner that when the fencing is subjected to lateral strains, slipping of the Wires and posts relative to each other Will not occur, and thus when forces are exerted laterally against the fencing, resistance to twisting of the posts is aided by the other Wires ot the fencing. l?urtherinore, the surface ot the post which opposes the ground in the flexing operation. may be made sufficiently narrow, as compared with the width ot the reinforcing flange of the post which extends laterally oi the fencing, to cause the desired resistance to he offered by the ground to the post for producing the most eilieient leather-sprlng action. lt Will also be manifest that by the combination oi these features, the lline-post may be made relatively lig'ht in Weight as no necessity exists for providing in the post to resist torsional strains, -metal in addition to that required lor rendering the posts sufficiently strong to resist lateral forces.

The constructions shown in Figs, 6, 7 and 8 present examples of another Way in which the Wires ll may be so associated with the line-posts of the resilient type above referred to, as to firmly secure these Wires to the line-posts, and afford the advantages hereinbefore set forth, A

Referring particularly to Figs. 6 and 7 the line-post therein illustrated is ot general,

lfshape in. cross-section, with the side theren oi" against which the longitudinal fence wires l1 extend, of convex form, as represented. .at 25. against this convex face by any suitable fastening means, those illustrated comprising a- Wire 26 which extends between its endg, around the rear side of the post and inter'- The Wires 1l may be secured messes against the surface more or less conform- .,ingly and cause such an association of the wine l1 with the post that there can be no relative slipping between the post and fen@- ing.

The principle'underlying the construction illustrated in Fig. 7 is 'also embodied in the construction illustrated in Fig. 8, wherein the post, 'instead of being of l..shape in crosssection is of general v'lV-shape, with the side thereof against which the fencing Wires ll extend, convened, as indicated at 28, and cooperating with the Wires ll as explained ofthe convex surface in Fig. 7

The provision of the posts as shown in Figs. 7 and 8 causes the fencing to beso related thereto when secured to the posts, as

' illustrated, as to permit posts with relatively narrow faces, against which the Wire-teneing` is secured, to be provided, and the fencing-Wires ll to be secured to the posts against slipping: and, in. fact, may be inadeof such narrow w1dth relative to the portion of the post Which extends laterally of the fencing, that the resistance offered by the around to the iiat-wised disposed side of the fiost in the iiexingoperation, will be that required for the most eliicient featherspring action..

What l claim as new and desire 'to seeuie by Letters Patent iszl. lna -fence, the combination of a resilim ent line-post having its lower resilient portion embedded in the ground, said post bef ing formed of longitudinally extending members disposed at an angle to each other, fencing extending across the line-post, and fence securing means on one face of the post adapted to hold the fencing at different vertical elevations against slipping thereon under torsional strains on the post, said `fencing extending at an angle to the other face of the post, the face against which said fencing hears being of less width than the other face disposed angel-arly thereto.

.2. ln a tence, the combination. o?? a resilient line-post of1 substantially Lebens in cross-section having its lower resilient por tion embedded in the ground, the 'face of one of the flanges oi the post being oset to provide spaced bearing surfaces, fencing en tending across said bearing surfaces, and means on tliezpost engaging the fencing at different vertical. elevations for holding the fencing firmly against said bearing surtaces, Ithe flange affording said bearing surfaces being o less Width than the other ilange of the post. l
