We consider elastic grains which repel upon contact according to the Hertz potential V = aδn, n &gt; 2, where δ is the overlap between adjacent grains and report numerical and analytical studies for the case of a 1-D chain of spherical grains to show that an impulse initiated at an end of a chain of Hertzian grains in contact, eventually propagates as a soliton for all n &gt; 2.
