1851, in excavating for the terminus of the Leeds sewerage, 
on the south side of the Suspension Bridge, below Knostrop, 
at the depth of ten feet, in a bed of gravel, with some other 
articles which displayed man's handiwork, and he thought 
it might have belonged to some Scandinavian fisherman. 
Fortunately, your museum possesses this object also, and a 
glance at it will convince us that it is the work of a later 
period than that of Danish rule in the North of England. 
And, while speaking on this subject, I would earnestly impress, 
not only upon the members of the Philosophical Society, but 
on others also, how useful it is for the promotion of true know- 
ledge that objects like those I have been describing should be 
collected together into one place, that they may thus be easily 
available for comparison and study, and how desirable it 
is that some means should be employed by which all 
such articles found in this part of the island should 
be brought to this museum as soon as discovered. It 
appears from Mr. Denny's account that other articles in metal 
were found with this leister, but they were afterwards dispersed, 
whereby we have probably lost the means of ascertaining 
more exactly the date of the deposit. 
You have in your museum another object, in many respects 
of still greater interest, and which I believe you owe to the 
zeal of my friend, your late secretary, Mr. O'Callaghan — I 
mean the curious ancient boat, or canoe, formed out of the 
solid trunk of a tree. It was found, I understand, lying on 
the rock, under six feet of soft laminated clay, at a place 
called the Tarn, in the parish of Giggleswick, which is un- 
derstood to have been the site of a lake, now drained. There 
is no mark about this boat to give us the slightest help in 
identifying its age, which may be very remote, and certainly 
cannot be very recent. Ancient boats of this general char- 
acter have often been found at considerable depths in many 
parts of our island, but, as they are somewhat heavy, and
