** 1978, Robert Hunt, A Historical Sketch of British Mining, page 63:Where the fynding of these affordeth a tempting likelihood, the tynners go to work casting up trenches before them, in depth 5 or 6 foote, more or lesse, as the loose ground went, and 3 or 4 in breadth, gathering up such shoad as this turning of the earth doth offer to their sight.
** 1986, Roger David Penhallurick, Tin in Antiquity, page 164:As mentioned above, many of the important tin streams are well away from any outcropping tin lodes, hence shoad, so Carew oversimplified his account.

** 1889, Records of the Geological Survey of India, page 41:It is manifest from the position of the neck that the great mass of material removed by denudation in forming the hollow in which it is seen exposed, must have been washed down the stream in question, and had diamonds occurred in that mass it is highly improbable that none should have been left in the bed and banks of the stream where their existence would certainly have been discovered by the old diamond seekers in former generations, who would have “shoaded” up the stream and have inevitably reached the neck.
** 1967, Charles Joseph Singer, A History of Technology - Volume 4, page 67:Until about 1875, the ancient methods of prospecting for a deposit whose presence was suspected from evidence such as the above were still in common use. they included shoading, trenching, and hushing.
