must have been lost in lakes or rivers, we may suppose that, 
falling upon mud and clay, which was soft from being under 
the water, they would gradually sink by their own weight, 
and thus add to the depth they would gain by the subsequent 
deposit from the water. I believe that such boats were in 
use in some parts of the country down to a comparative late 
date, and the interesting specimen to which I am alluding 
possesses peculiarities which seem to show that it is not a 
very early example. 
Giggleswick, where this boat was found, is closely adjacent 
to Settle, where some of the most interesting of the York- 
shire caves are met with, and which must, in early times, 
have been a very wild and uncultured district. A good 
account of the caves examined in King's Scarr, near Settle, 
and of the various objects found in them, is given in the first 
volume of my friend Mr. Roach Smith's valuable Collectanea 
Ant iqua. As caves of this description are now very well 
known, I will not occupy your time in describing them, but 
I will merely state that they contained bones of animals, 
including the hog and the bear, many of which appeared to 
have been gnawed ; a great variety of objects of antiquity, 
most of them evidently of Roman work, and apparently late ; 
and a good number of coins. These latter established, beyond 
a doubt, the lateness of the date at which these caves had 
been occupied by men. Some of them were Roman, chiefly 
of the Emperors of the Constantine family, which formed the 
mass of the monetary circulation in Britain at the close of the 
Roman period, but the greater proportion of them consisted 
of the rude imitations of the coinage of these Emperors which 
were made and circulated after the withdrawal of the Roman 
power, and which cannot, therefore, be older than the fifth 
century. Some of these caves, in Craven, have been more 
fully examined since the account printed by Mr. Roach 
Smith, in the Collectanea Antiqua ; and the new discoveries
