One of the most important monuments that have come down to us is that of Carnac. The alignments of Menec, Kermario, and Kerlescant include 1,771 menhirs, of which 675 are still standing. The alignments of Erdeven, which succeed those of Carnac, extend for a length of more than a mile and a half. They originally included 1,030 menhirs, of which 288 are still extant. The archæologists of Brittany, carried away perhaps by their patriotic enthusiasm, claim that when these monuments were intact they included two thousand menhirs. What is really certain, however, is that a definite plan was evidently followed, the distances between the alignments tallying exactly; the menhirs being set up in straight parallel lines gradually decreasing in size towards the east. Excavations near them have brought to light fragments of charcoal, masses of cinders, chips of silicate of flint, with numerous fragments of pottery, and tools made of quartzite, granite, schist, and diorite, similar to those met with under all the other megaliths of Morbihan. This is yet another proof, if such were needed, that they were all the work of the same race and all probably date from the same period. The number of megalithic monuments in the world is simply incalculable. M. A. Bertrand estimates the total number in France as 2,582, distributed in 66 departments and 1,200 communes. They are most numerous of all in Brittany; there are 491 in the Côtes-du-Nord, 530 in Ille-et-Vilaine. I am not sure of the number in Morbihan, but I know it is very considerable. The commission appointed at the instigation of Henry Martin decided that there were as many as 6,310 megaliths in France, but then amongst these were included polishing stones and cup-shaped stones, with other similar relics of the remote past. Lastly, a report recently presented to the Chamber of Deputies by M. A. Proust estimates at 419 the number of groups classed by government. In other countries these numbers are greatly exceeded. There are 2,000 megaliths in the Orkney Islands and a great many in the extreme north of Scania, and in Otranto in the southern extremity of Europe, where they resemble the _pedras fittas_ of Sardinia. Pallas, and after him, Haxthausen, tells us that there are thousands of kurganes in the steppes of Central and Southern Russia.19 These kurganes are cromlechs, tombs surmounted by upright stones, square or conical hypogea, all scattered about without any apparent system, surmounted by roughly sculptured female busts, known amongst the common people as _kamena baba_, or stone women. Tumuli, too, abound on the shores of the Irtisch and of the Yenisei, mute witnesses to the former presence of a vanished race of which we know neither the ancestors nor the descendants. These monuments are, however, by some attributed to the Tchoudes, a people who came from the Altai Mountains. The Esthonians, the Ogris or Ulgres, the Finns, and perhaps even the Celts, are supposed to be branches of
