Horizontal grooves occur on a few rims (See Plate IV, figures 10, 11) ; 
and a deep one can be seen on the edge of a few rims; others occur on the 
peaks of a few rims (See Plate II, figure 13, which shows the top of the 
angular lip in Plate IX, figure 23). There are groups of three, four, and 
five, short, horizontal grooves on the bowls of a number of earthenware 
pipes (Plate XV, figure 45), the grooves being graduated in length, with 
the longest one at the top on a few bowls. Only the lowest groove of a 
group of four, on another pipe, is shorter than the others. The grooves 
occur in combination with other decorative elements on a few other pipes; 
most of them having a round pit at both ends of the groove; but one, in 
addition to the pits, has a row of more or less round pits on the ridge 
between the two upper grooves and on the one above the lower groove. 
The grooves are associated with a more complex type of docoration on a 
badly broken pipe bowl (Cat. No. VIII-F-13123a) and they are combined 
with a probable bird form and circles on another (Cat. No. VIII-F-13137). 
Wide, deep, encircling grooves are the sole decoration on bowls of a 
few earthenware pipes (Cat. No. VIII-F-11074) ; and they are combined 
with other decoration on others. There are one and two, wide, encircling 
grooves between bands of three, six, seven, and nine, finer, encircling 
grooves on several pipes (See Plate XV, figures 41 and 44). 
The grooves and lines go only part of the way around the bowls of 
some of the earthenware pipes, especially those with human face masks, 
owl heads, and lunate forms on the back. There is a group of six grooves, 
with a row of round depressions below, on the back of the human head on 
the pipe bowl seen in Plate XVI, figure 21. The decoration on a few 
broken bowls is like that on the one in Plate XVI, figure 12. The back of 
the bowls in Plate XVI, figures 3, 14, and 18, bears a similar pattern, except 
that there is a row of pits in each of the deeper grooves and along the 
bottom of the collar. The decoration on the front of the broken bowl, in 
Plate XV, figure 42, consists of eight grooves, with pits at both ends of 
each groove and with a row of similar pits along the top and bottom of the 
collar. 
The longitudinal grooves on two sides of the stem fragment of an 
earthenware pipe, seen in Plate XVI, figure 27 b, were probably intended to 
be ornamental. 
Curved grooves can be seen on the rim fragment in Plate V, figure 1. 
Circles occur on many rim, neck, and shoulder fragments of pots, but 
apparently never on all three parts of the same pot, and on a few earthen- 
ware pipes. They are rarely seen on the extremely convex collars. 
Most of the circles seen on pots and pipes are simple. Others have 
a small, round pit in the centre (See Plate VI, figure 25, Plate VIII, 
figure 12, Plate IX, figures 19, 21, 24, and Plate X, figure 20), and, in one 
case, eight small pits around the central pit; a large hollow in the centre 
(See Plate VIII, figure 13) ; a small oblong depression in the centre (See 
Plate VI, figure 29, Plate VIII, figures 14, 26, and Plate IX, figures 16, 18, 
20) ; an arrow-head like depression in the centre (See Plate VIII, figure 16) ; 
and short, linear depressions (See Plate IX, figure 12) . Concentric circles 
occur on only one of the rims (See Plate VIII, figure 15). These and the 
circles with a pit in the centre, although produced by a different method, 
remind one of the nucleated circles on Eskimo artifacts (See Hoffman, 
pages 813-827 and 933-935).
