The name for the outer wall of a house, however, is _héine_, or _héline_, which signifies a mud or adobe inclosure; from _héliwe_, mud (or mud-and-ash) mortar, and _úline_, an inclosure. Since in usage this refers to the outer wall of a house or other simple structure, but not to that of a town or assemblage of houses, its origin may with equal propriety be attributed to the mud-plastered corral or adobe sides or inclosures of such rancherias as I have already described.[7] [7] In my "Study of Pueblo Pottery," etc. (Fourth Annual Report of the Bureau of Ethnology, 1882-83), I have said that "The archaic name for a building or walled structure is _héshota_, a contraction of the now obsolete term _héshotapone_; from _hésho_, gum, or resin-like; _shótaie_, leaned or placed together convergingly; _tápoane_, a roof (covering) of wood, or a roof (covering) supported by wood." I regret to say that the etymology of this word as thus rendered was not quite correct, and therefore its meaning as interpreted in the passage which immediately followed was also mistaken. It is quite true that _hésho_ signifies gum or resin, etc. (referring, as I then supposed, to _áhesho_, or gum rock, a name for lava; used constructively in the oldest round huts of the basaltic regions); but the root _he_ enters into many other compounds, such as not only wax, gum, pitch, metal (as being rock-pitch, that is, melted from rocks), etc., but also mud, clay-paste, mud-mortar, and finally adobe, as being dried mud mortar; hence walls made either with or of adobe, etc. Had I been, at the time of this first writing, as familiar with the language as I now am I should not have connected as a single root _he_ and _sho_, making _hésho_ (gum or pitch) of it. For, as elsewhere stated in the same essay, _shówe_ signifies canes, (_shóole_, a cane or reed), and it now appears that the syllable thus derived formed a root by itself. But I had not then learned that the greater number of the ruins of southern Arizona, especially of the plains, consisted of gabion-like walls, that is, of walls made by packing stiff earth or rubble mortar or cement between double or parallel cane-wattled stockades, and then heavily plastering this exterior or casing (as was the case in the main walls of the celebrated Casa Grande and the temple mound of Los Muertos); or else, in less massive ruins of lesser walls the cores or supports of which consisted of close-set posts lathed with reeds or canes, the mud or cement being built up either side of these cores, or, in case of the thinnest walls, such as partitions, merely plastered to either face.
