The Barrows on the Plain were built of the materials most easily accessible, mould, chalk, and flints, with occasional fragments of Sarsen. As has already been recorded, fragments of Foreign Stone from Stonehenge have been found in one of those forming the group which lay immediately south-west of the circle, but now destroyed by cultivation. The method of procedure was simple. A grave would in many cases be dug sufficiently long to contain the body if buried by inhumation in a crouching position. This grave would vary in depth from a few inches to six feet. Sometimes blocks of Sarsen would be built over the body to protect it. The crouching posture is specially noteworthy. The knees are drawn up to the trunk and the legs bent on the thighs, while the arms are closed towards the chest, and the hands over the face. There has been some speculation as to the significance of this particular attitude. Some have seen in it that of an unborn infant, others the natural position in death, others again have maintained it was the primaeval posture of sleep. It seems quite possible, however, that the position may be due to mere utilitarian motives as being more compact for the purpose of burial. The lie of the inhumed skeleton is usually with the head to the north; exceptions show that the east, south-east, and south-west, have sometimes been selected, but never due south. Interments with the head to the west, as in Christian burial, are very rare. When burial by cremation took place, it is evident that the actual rite of burning took place elsewhere, and that the calcined remains were brought to the plain for burial. In some cases the ashes were conveyed to the spot wrapped in skins, or possibly in some rude form of cloth; more frequently in Wiltshire they were deposited in cinerary urns. The proportion of urn burial is as three to one. This method of conducting the cremation at one spot, and the subsequent removal of the ashes to another, generally considered sacred, is not uncommon, even at the present day. [Illustration: The 'Stonehenge Urn'.] The urns were sometimes placed upright, at others they were inverted, the latter being the more common custom. The mouths of these urns were frequently stopped with clay, or closely packed flints. The urns vary in size considerably from nine inches to fifteen in height, and from about a pint to more than a bushel in capacity. A veritable giant rather over two feet high, the largest of its kind hitherto found in Wiltshire, is preserved in the Salisbury and South Wilts Museum. Another only two inches less in height was recovered from a Barrow within a third of a mile from Stonehenge. In most cases various objects were found associated with these interments, such as drinking-cups, food vessels, incense-cups, weapons and ornaments. [Illustration: Beaker.
