Radical mine, quarry.—As iu the case of palafittes, tlie radical mine or quarry needs no derivatives. Indeed, it seems to be necessary to justify its use at all. This symbol may be very handy iu prehistoric charts to indicate the source whence materials, such as silex, sand- stone, amber, jade, and other minerals and rocks are obtained. For example, a dolmen is constructed of rocks not to be found iu its imme- diate locality ; the symbol mine is placed at the nearest point where the materials iu question are to be fouud, and a line is drawn from this spot to the dolmen, to show the connection of the two. § 4. Completnentary symbols. The complementary symbols are simple signs, which, in combination with the preceding, render archoeological identification as complete as possible. In the execution of the chart, they play a part analogous to the accents and punctuation-marks in writing. These complementaries are grouped iu three categories: the first relates to the state of preser- vation iu which the monuments are found; the second to the number of ruins, &c.; the third relates to their age. First category—The state of the monuments.—This category embraces four symbols. The circle under a symbol indicates that the site has been explored. The oblique line crossing the symbol designates a dilap- idated monument, menhirs tumbling over, &c. The double-diagonal crossing upon the symbol indicates the site of monuments entirely iu ruius or destroyed. Finally, a short oblique line on the right side of the symbol points out false identifications, wrong references, &c. Cavern. xJ. J^ J3. jL Artificial 4 AX A Menhir.
