Note XI-12 — Chapter XI · ANTIQUITIES OF ARIZONA AND NEW MEXICO.

Adobes are properly sun-dried bricks without any particular reference to the exact quality or proportions of the ingredients, many varieties of earth or clay being employed, according to the locality and the nature of the structure, with or without a mixture of straw or pebbles. But adobe is a very convenient word to indicate the material itself without reference to the form and size of its blocks or the exact nature of its ingredients; and such a use of the word seems allowable.
