DINGWALL, a royal and police burgh and county town of the shire of Ross
and Cromarty, Scotland. Pop. (1901) 2519. It is situated near the head
of Cromarty Firth where the valley of the Peffery unites with the
alluvial lands at the mouth of the Conon, 18-1/2 m. N.W. of Inverness by
the Highland railway. Its name, derived from the Scandinavian
_Thingvollr_, "field or meeting-place of the _thing_," or local
assembly, preserves the Norse origin of the town; its Gaelic designation
is Inverpefferon, "the mouth of the Peffery." The 18th-century town
house, and some remains of the ancient mansion of the once powerful
earls of Ross still exist. There is also a public park. An obelisk, 57
ft. high, was erected over the grave of the 1st earl of Cromarty. The
town belongs to the Wick district group of parliamentary burghs. It is a
flourishing distributing centre and has an important corn market and
auction marts. Some shipping is carried on at the harbour at the mouth
of the Peffery, about a mile below the burgh. Branch lines of the
Highland railway run to Strathpeffer and to Strome Ferry and Kyle of
Lochalsh (for Skye). Alexander II. created Dingwall a royal borough in
1226, and its charter was renewed by James IV. On the top of Knockfarrel
(Gaelic, _cnoc_, hill; _faire_, watch, or guard), a hill about 3 m. to
the west, is a large and very complete vitrified fort with ramparts.

DINKA (called by the Arabs _Jange_), a widely spread negro people
dwelling on the right bank of the White Nile to about 12 deg. N., around
the mouth of the Babr-el-Ghazal, along the right bank of that river and
on the banks of the lower Sobat. Like the Shilluk, they were greatly
harried from the north by Nuba-Arabic tribes, but remained comparatively
free owing to the vast extent of their country, estimated to cover
40,000 sq. m., and their energy in defending themselves. They are a tall
race with skins of almost blue black. The men wear practically no
clothes, married women having a short apron, and unmarried girls a
fringe of iron cones round the waist. They tattoo themselves with tribal
marks, and extract the lower incisors; they also pierce the ears and lip
for the attachment of ornaments, and wear a variety of feather, iron,
ivory and brass ornaments. Nearly all shave the head, but
