series of recurrent triangles,’ leading to a ‘chevron’ effect; in (c) these triangles 
are enhanced by ‘hachure’ or ‘ hatching’ (a term borrowed from the engraver’s 
art), and in (d) by ‘cross-hatching.’ In (6), on the other hand, motif and effect 
are alike ‘chevron.’ 
In composite patterns the minor elements must be located by reference to the 
major element which they enhance, or on which they are based, and subsequent 
phrases must define their relations to each other; ¢.g., the motive (a) would be 
described as ‘between parallel lines, a convergent series of recurrent alternate 
triangles’; but in (g)

the ‘recurrent triangles ’ would be not ‘alternate’ but ‘ opposite,’ and the ‘effect ’ 
is that of a string of lozenges; and in (’) 
the triangles would be not ‘recurrent’ but ‘intermittent’ or ‘sparse’; while the 
‘effect’ is that of a hexagon pattern. Similarly in figures (ce), (g), and (2) the 
triangles would be ‘hachured’ or ‘hatched’ from the left, (i.e., when viewed with 
their dase downwards and their apex upwards), for the reason that the ‘ generating 
line’ of the ‘hachures’ is the left-hand side of the triangle, to which they are 
parallels. In figure (e) the chevrons are ‘enhanced’ by ‘ external repetition ’ of 
their generating lines; in figure (/) the enhancement is ‘internal.’ It might 
eventually be possible to subsume the special term ‘hachure’ under the general 
term ‘ enhancement,’ and to describe the triangles of (c), (v7), and (2) as ‘enhanced 
internally from the left.’ 
The elaboration of such a terminology as is here proposed should of course be 
gradual; it should be based upon careful comparison of terminologies actually 
employed in the past by expert technologists ; and it should conform in its syntax 
to the approved usages of heraldry, systematic botany, and the like, which 
fortunately agree in essentials. It should take account, from the first, of foreign 
synonyms, and proceed—like other artificial terminologies—partly by the incorpo- 
ration of brief graphic idioms from the vocabulary of the industries concerned, 
partly by judicious coinage of words, as in zoology, from Greek or other universal 
vocabularies. 
Much may be done in the meantime to fix current idiom by detailed descrip- 
tive analysis of some of the commoner geometrical forms, such as the triangle 
(which has formed the basis of illustration here), the wavy line, the spiral, or the 
plait. A conspicuous instance of the confusion produced by neglect of ‘ termino- 
logical exactitude’ is the greater part of the recent literature of basketry ; and 
this is the less excusable, because in the allied art of weaving an ancient, idiomatic, 
and peculiarly accurate vocabulary exists in nearly every European language.

British Association. Any persons with any known non-Welsh ancestors are not
