RECORDS OF THE AUSTRALIAN MUSEUM. 
Both above these circles, and below the large spiral, is a series 
of horizontal grooves, starting from the edge of the implement 
inwards, and not meeting in the middle line, but leaving a clear 
median space, that below the spiral being wider than the upper 
one. The upper incisions are seven on the right, and eight on 
the left, the lower six on either side. 
The reverse of this implement (PI. i., Fig. 2) is differently 
incised. In the place of the large almost central spiral is a rather 
roughly executed series of circles concentric within one another * 
the longest diameter is two and two-eighths inches. Surmounting 
this figure is a three-quarters circular representation in which the 
grooves are very much finer, fainter, and closer together, leaving 
a large unincised space, the free end almost touching the circum- 
ference of the central group of circles. If completed, the figure 
would also be circular in form. There are, I think, ten grooves. 
The surface of the implement below the central circles is trans- 
versely grooved in a manner precisely similar to that of the front 
face, the grooves on the left hand numbering thirteen, but those 
on the right are too indistinct for enumeration. 
This peculiar implement has been profusely ruddled, so much 
so as to almost fill up some of the grooves. Furthermore, the 
broken base shows traces of adherent gum cement, which extends 
on the fractured end. I infer from this either that it lias 
formed a portion of a mounted implement, or when in the posses- 
sion of its sable owner was fractured and possibly repaired. The 
colour is fast, and does not soil the hand. 
This interesting implement was presented some years ago by a 
Mr. Dunlop, and is said to come from North Queensland, but the 
precise locality is unknown. 
As having a possible bearing on the use of this instrument, it 
is necessary to refer to two others presented by the same donor, 
and at the same time. In both cases, however, there is no incised 
sculpture. One is a linear-oval flat, pebble, four inches long and 
two wide, shaped generally like a “ Bull-roarer.” It is similarly 
ruddled, and the smaller end is covered with gum cement on both 
sides. The second specimen is a Hat shale pebble, broad-oval in 
shape, eight and a- quarter inches long, by four and a-half wide, 
unincised, but profusely ruddled on both aspects, although the 
ruddle is lighter in colour than in the incised implement (PI. i., 
Figs. 1 and 2. The surfaces are speckled over with magenta 
coloured dots or spots. 
With regard to the use of these implements I can do no more 
than offer a surmise. — The care bestowed on the spiral and circular 
figures on the one hand, and the thick coating of colour on the 
other, at once place on one side the supposition that they might 
have been used for grinding stones, for which purpose the shape
