of the hill, then rises high upon the truncated edges of the Cam-
brian rock, and even caps one of the summits of the noble Queenaig.
The lower beds of the quartz-rock, which rest upon the Cambrian
sandstone, are here very striking, from exhibiting on their surface
large round knobs on the tops of cylindrical bodies which pass
through several layers and are unquestionably the infillings of ex-
cavations made by Annelides. (See PL XIII. figs. 29, 30.) The
quantities of these pipe- shaped bodies are astonishing ; and as they
also occur in the same stratum (^. e. near the base of the lower
quartz-rock) and on the west shore of the Kyle of Durness, we may
infer that they are the oldest vestiges of hfe which can be detected
in the Lower Silurian rocks of the I^^orth Highlands.
In illustration of the manner in which these tubular bodies tra-
verse the layers of quartz-rock or crystallized sandstone on the north-
eastern flank of Queenaig, I may here repeat a woodcut from p. 41 of
^ Siluria ' (new edit.), representing Annelide-burrows in the quartz-
rock of the Stiper Stones, a well-known Lower Silurian rock of
Shropshire. The trumpet-shaped openings, sometimes 2 or 3 inches
in diameter, the tubular cavities, and the cylindrical casts (identical
with forms found thirty years ago on the west shore of the Kyle of
Durness by Sedgwick and myself), leave no room for doubt that they
also represent the Annelides of the English Stiper Stones and of the
Potsdam Sandstone or Lowest Silurian rock of North America (Sco-
lithus linearis of Hall).
Pig. 5. — Fossil Annelide-tuhes (Scolithus linearis) from the Stiper
Stones, resembling those from Assynt. (Prom ' Siluria,' new edit,
p. 41.)
Descending into the Yale and Loch of Assynt, upon the surface of
the lower quartz-rock, its upper layers are clearly seen to become
more schistose and shaly, and also to exhibit fucoidal and other
impressions. Then the succeeding limestone expands in terrace over
terrace, and is best exposed in mounting from the edge of the loch,
or from the west by north, to the hill called Cnoc-an-drein, on the
east by south. In this walk you pass over a succession of parallel
ridges for the space of about three-quarters of a mile, each cal-
careous band dipping easterly at about 25°. Some of the limestone

is of deep-grey or dull-blue colour; other parts are light-grey,

Public domain

This work is in the public domain in its country of origin and other countries and areas where the copyright term is the author's life plus 70 years or fewer.

This work is in the public domain in the United States because it was published (or registered with the U.S. Copyright Office) before January 1, 1929.

This tag is designed for use where there may be a need to assert that any enhancements (eg brightness, contrast, colour-matching, sharpening) are in themselves insufficiently creative to generate a new copyright. It can be used where it is unknown whether any enhancements have been made, as well as when the enhancements are clear but insufficient. For known raw unenhanced scans you can use an appropriate {{PD-old}} tag instead. For usage, see Commons:When to use the PD-scan tag.
