Additional Notes :—1625. The record for this and 
the next flood can be seen on the Friar's Wall, the first 
buttress from Tower Street, These two marks read 17 feet 
10 inches and 17 feet 1| inches above the present “ summer 
level” of 16 feet 9 inches Taking the difference of the 
prevent flood (5 inches) between here and Ouse Bridge the 
heights would be 18 feet 3 inches and 17 feet 6J inches 
respectively. But Skeldergate Bridge, its approaches, and the 
Coffer Dams must certainly have pounded back the water at 
Friar’s Wall, so that probably most of the difference (9 inches) 
between the latter and Castle Mills Locks should be added at 
well. This makes the probable height of the two floods as 
least equal to the usually accepted values. 
1689. This value is probably two feet too low, since careful 
comparisons are made with that of 1636. 
1831. The mark for this at Marygate Tanyard stood 4 
inches above the flood of 1795 and 14 inches above that of 
1809. Frequenters of Ouse Bridge Inn report it to have been 
some two inches lower than the mark there of 1763; but this 
can hardly be correct. Several old inhabitants were able to 
give pretty precise information. Mr. W. Monkhouse informed 
me that they could not get into the cross-lane from the foot of 
Marygate to S. Mary’s. This means 9 inches higher at least , 
although alterations have been made. Mr. Fletcher , Joiner, 
&c., Coppergate, then lived, a boy of 12, at 5, Providence 
Place, near Rowntree’s Cocoa Works. The water then just 
entered the oven. This time it was 11 inches below. Hence the 
height was at least a foot more in 1831 than 1892. Mr. Creer 
obtained a record from Tower Street which indicated a 
difference of 14 inches there, and himself adopts 17 feet 1 inch 
as the height of this flood. Hence it seems safe to accept the 
1831 flood as 1 foot, almost exactly, higher than that of 1892. 
The Foss, as shown by the record outside the Merchants’ Hall 
Chapel door, rose 13J inches higher in 1831. Mr. Reader, 
Ferryman at Naburn, placed a brass plate on his door in 1831. 
The flood there, in 1892, reached within 11 inches of this. 
No flood in the interval touched the door; i.e. none rose 
within 8 inches of 1892. It just reached this level at the 
“ Slingsby ” flood, 1869.
