1. Many of the barrows, two of which are in obvious connection with the great stones, are shown by their forms and contents to be of the largest type of Bronze Age barrows, known as Round Barrows (for instance, gold relics, glass beads, ivory and cremated remains are signs of lateness). This being so, it is significant that chippings of the stones brought _from a distance_ to Stonehenge are found even in undisturbed barrows of this kind, where the action of earthworms and rabbits in introducing foreign elements is hardly possible. It is clear, therefore, that the building of Stonehenge was at least begun _late_ in that period. There is the point also that with the exception of two, the circumjacent barrows are _not_ in any relation with the great circle, and are therefore not later. 2. The contents of the barrows earlier than Stonehenge have some imported articles which must have come from the continent not before the fifth century B.C. One even is stated to have contained a socketed celt, pointing to the late fourth century. But late Celtic antiquities are wholly absent, which makes it hardly possible that the barrows should be as late as the second century B.C. 3. The skilful hewing and fitting of the huge blocks of Wiltshire Sarsen stone are of the same stage in technical development as the triliths of Syria and Tripoli, and the great Doric temple of Segesta in Sicily, which latter was constructed about 415 B.C. From these and similar indications he concludes that the gradual building of the great monument was probably between 300 and 150 B.C. He is now inclined to place the date earlier. In 1901 a small committee of the Society of Antiquaries and two other societies reported on the desirability of setting upright a very large leaning stone at Stonehenge, which showed signs of breaking up as well as of falling still further down. It was successfully raised in September of that year, and it is from the necessary excavations—which were very carefully and scientifically conducted—that various data were collected by Mr. William Gowland, and printed in _Archæologia_, vol. 58 (1902). No object of metal was found, except one small trace of bronze or copper. From this circumstance he concludes that Stonehenge was constructed at the time when the Neolithic Age was passing into the Bronze Age, and that has been tentatively placed at about 1400 B.C., or not later. Sir Norman Lockyer, he mentions, had recently attempted to determine the date on the hypothesis that the monument was a solar temple, since, as is well known, the midsummer sun rises exactly in the line of the chief avenue from the temple, and exactly over a large detached stone placed no doubt for this very purpose. He deduced a date as early as 1700 B.C.
