Abstract: For athletic contests between teams of individuals on a field or court it is customary to provide certain markings of the various portions of the field within which the game is conducted. Heretofore it has been common practice to utilize chalk or lime to mark the boundary lines. This method has not been satisfactory because as rain descends the chalk or lime is spread and the field markings are lost. As soon as a contestant runs over the boundary line, as he must in such contests as baseball or football, the marks are obliterated so that it is difficult for the officials judging the game to make proper decisions. I have developed a permanent resilient marker strip which can readily be installed by the use of a trencher to dig a narrow trench into which a resislient base having a plurality of spaced flexible pegs project upwardly to have their tips visible above the surface of the ground. The pegs are closely spaced and are visible over a long distance.
