ornaments, and again others with no sign at all, but yet respected as stones of special meaning by the population, and called “hot stone,” “pointed stone,” “heath stone,” “child’s stone,” etc. Other stones have basin-like or platter-like depressions, and finally there are outcropping rocks with marks of one kind or another, holes, rents, clefts, etc. A further great difficulty hampering the deciphering of these wonderful stones is the lack of opportunities for comparison and experience. I have been markedly favored in this respect by my sojourn and wanderings in valley, mountain and alp. Western Switzerland is a very paradise for investigations of this kind, especially the lake country and the upper part of the canton of Solothurn (Soleure). A third difficulty, often insuperable, lies in the nonexistence of appropriate good maps for comparison. In this respect too we are well off in Switzerland. According to my observations in this field, now continued nearly 12 years, prehistoric man had: (1) His land or province survey; (2) his circle, district, and communal surveys, in reference to which (3) the Alpine surveys deserve special mention, in cantons which down to the present day know nothing of such surveys; (4) private and special surveys. Thus it seems that my observations lend full confirmation to the oldest historic or traditional statements concerning the tenure of land of the Kelto-Germans or Germano-Kelts.
