Boas] STRUCTURE OF BASKETS 187 
circling coils bound the central portion, which varies from a true center 
to almost the entire piece. Plates 8, c; 9, c, and 10 illustrate these 
lids, which include all types of coiled and slat work, and are classified 
under one heading simply on account of their shape, their relation to 
the orifice they cover, and the way in which they are fastened to the 
baskets. They are Lillooet and Thompson specimens. A variation 
of Type I is characterized by the following features: The lid is flat, 
but smaller than the orifice, so that it requires a flange consisting of 
a few coils sewed around on the inside of the basket near the rim on 
which to rest. This variety is usually found on shapes which are 
smaller at the base than at the mouth, such as burden baskets; and 
is illustrated by Plate 11, a. The flange is usually high enough so 
that the lid is on a level with the rim. 
The lids of the second type are of the same construction as those 
belonging to the first; they are flat and of watch-spring or parallel 
coils, but possess a flange which is attached to them instead of to 
the basket. This is made separately of rarely more than two coils, 
unless the basket is very large, and is either of the spiral or ring 
variety. Sometimes, instead of this, a flat and fairly broad piece of 
sapwood is used hoop fashion, and is covered with sewing splints in 
the usual manner. The flange is sewed very close to the edge of the 
lid, as the latter is usually constructed so that it barely covers the 
opening, the slight projection usually not extending beyond the rim 
coil of the mouth on which it rests. 
The flange is made to slant outward a few degrees, fitting the 
mouth quite snugly and even requiring a slight pressure to push it 
down, because the bottom coil is just a fraction larger than the rim 
coil, which must give a little to admit it (fig. 17, a, b). In order to 
remove it, it is necessary to give it a quick tug. LLoops—or more 
recently, knobs—furnish a hold. Since such lids can not fall off, only 
the larger baskets are provided with hinges to hold them. 
A variant of this type (II, b) which is made by a few people, but 
which has never attained much popularity, has a flange which is 
deeper than the other kind, usually being built of three or four coils. 
It slopes inward from the top toward the bottom (fig. 17, ¢), the 
lowest coil or ring being of a diameter less than the mouth, the high- 
est being slightly wider, so that the lid may be pressed on and held 
firmly like a plug in a hole. But practically this is not feasible, for, 
on account of the springy nature of the coil, the lid frequently works 
out when the basket is moved about. Therefore, it is considered as 
inferior to the lid with a diverging flange which is used more often 
now than any other. 
The third type ranks second in popularity and includes flat and 
conoid shapes. The flat variety possesses a flange, but this is not of 
a separate piece which is later applied to the lid, but is made of the
