Charles Francis Atkinson, 1911 Encyclopædia Britannica (1911)
“ Military transport—other than water and rail—may be classed in respect of the means employed as draught and pack, and in respect of its organization and functions as transport on the line of communications and transport in the field, the latter being subdivided into first line and second line. The British army, on account of its frequent expeditions into undeveloped countries, makes a large—in the view of many, far too large—use of pack transport, for which mules, camels and human carriers are employed. ”
