In the centre he found a long rectangular chamber, measuring 52 feet in length by 5 feet in width internally, and divided into two equal compartments by two stones cut away in the centre, so as to leave a hole 1 foot 6 inches wide by 3 feet high. A similar but smaller hole exists on the side, and is identical with those found in the long barrows at Rodmarton and Avening in Gloucestershire.[418] Mr. Lukis, among other things, found an immense quantity of broken pottery, some of very fine quality. Two vases which he was enabled to restore are interesting from their general resemblance to the two which Mr. Bateman found in Arbor Low ([woodcut No. 31]). Though not exactly the same in form, there can be little doubt that they belong to the same age.

About a mile from this example, Mr. Lukis mentions a still larger one. It measures 81 feet in length by 6 feet in width, is divided into two compartments like the one just described, and has also a holed entrance. He also measured two in Finistère, one 76 feet, the other 66 feet, in length, and both 6 feet wide. Both, however, had been rifled long ago, and are now mere ruins. More, no doubt, would be found if looked for. Indeed, these straight-lined "allées couvertes," or "Grottes des fées," without cells, as the French call them, as before mentioned, are the most characteristic, if not the most common, form of French rude-stone monuments. The only other place where they are equally common is Drenthe, and it may be that this side hole at Kerlescant is an approach to the side entrance so usual in that province.
At Plouharnel, about a mile and a half westward from Mont St.-Michel, a double dolmen was opened a good many years ago. In it were found some beautiful gold ornaments, others in bronze, and some celts or stone axes in jade[420]—all these, like those of Mont St.-Michel, belonging evidently to what antiquaries call the latest period of the Polished Stone age; but until it is determined what that age is, it does not help us much to a date.
