(b) The Foreign Stones are still a matter of debate. They have assuredly been brought from a distance. This is unusual; megalithic structures are usually built of materials found close at hand. ([See page 20.])

IV. How the Monument was Erected
The large monoliths of Sarsen Stone were first of all roughly shaped as they lay in situ on the Plain and then transported to the chosen site.
The Foreign Stones were also dressed on the spot before erection.
The entire work was performed with stone tools of the roughest description, weighing from half a pound to over sixty pounds. ([See p. 40.])
The only trace of metal discovered in 1901, was a small stain of bronze on one stone, caused by contact with the stone of some very small bronze object, possibly an ornament. ([See page 53.])
The large Trilithons were erected from the centre of the site.
