hat of 1830, six
times that of 1770 and fifteen times that of 1660. Camborne was the
scene of the scientific labours of Richard Trevithick (1771-1833), the
engineer, born in the neighbouring parish of Illogan, and of William
Bickford, the inventor of the safety-fuse, a native of Camborne. Three
fairs on the feasts of St Martin and St Peter and on 25th of February
were granted in 1708. The two former are still held, the last has been
transferred to the 7th of March. A Tuesday market formed the subject of
a judicial inquiry in 1768, but since the middle of the 19th century it
has been held on Saturdays.

CAMBRAI, a town of northern France, capital of an arrondissement in the
department of Nord, 37 m. S.S.E. of Lille on the main line of the
Northern railway. Pop. (1906) 21,791. Cambrai is situated on the right
and eastern bank of the Scheldt (arms of which traverse the west of the
town) and at one extremity of the canal of St Quentin. The
fortifications with which it was formerly surrounded have been for the
most part demolished. The fosses have been filled up and the ramparts in
part levelled to make way, as the suburbs extended, for avenues
stretching out on all sides. The chief survivals from the demolition are
the huge square citadel, which rises to the east of the town, the
chateau de Selles, a good specimen of the military architecture of the
13th century, and, among other gates, the Porte Notre-Dame, a stone and
brick structure of the early 17th century. Handsome boulevards now skirt
the town, the streets of which are clean and well-ordered, and a large
public garden extends at the foot of the citadel, with a statue of
Enguerrand de Monstrelet the chronicler. The former cathedral of Cambrai
was destroyed after the Revolution. The present cathedral of Notre-Dame
is a church of the 19th century built on the site of the old abbey
church of St Sepulchre. Among other monuments it contains that of
Fenelon, archbishop from 1695 to 1715, by David d'Angers. The church of
St Gery (18th century) contains, among other works of art, a marble
rood-screen of Renaissance workmanship. The Place d'Armes, a large
square in the centre of the town, is bordered on the north by a handsome
hotel de ville built in 1634 and rebuilt in the 19th century. The Tour
St Martin is an old church-tower of the 15th and 18th centuries
transformed into a belfry. The triple stone portal, which gave entrance
to the former archiepiscopal palace, is a
