north-east side of Eombold's Moor; for a glacier would 
surely have carried Limestone from the upper part of the 
Wharfe valley to the area where the scattered blocks of 
Grit are the most abundant. This immense bed of tumbled 
and broken rocks extends over an area of not less than four 
square miles, many of the blocks weighing at least from 
30 to 50 tons. (See plate II.) 
Amongst the thousands of scattered blocks and fragments 
there are many which must have been transported from a 
distant part of the moor, while most of them could not have 
tumbled to their present position. It is difficult to say how 
many beds of the fine white saccharoid sandstone, called 
calliarcl, might be found on Rombolds Moor ; but I have no 
hesitation in asserting that numerous blocks of this calliard 
now occupy portions at considerable distances from the parent 
rock. They may be seen on the top of the moor, and in 
greater abundance strewn along the north-east slopes, about 
50 yards east of Ilkley College, and between the smooth 
grassy slopes, on which upper Ilkley stands, at the base of 
the cliffs. This is one of the most impressive assemblages of 
loose blocks I have anywhere seen. Many of the blocks arc 
calliard where no calliard in situ can be found in the neigh- 
bourhood. (See plate III.) 
At the north-eastern corner of the lowest escarpment of 
the moor there is a remarkable rocky phenomenon, called 
the Hanging Stones or Cow and Calf, which deserves a 
passing notice. Tradition says that the huge piece of rock 
to the north of the main cliff was detached and roUed to its 
present position during a terrible storm at the close of last 
century ; and certainly one face of this so-called Calf retains 
the appearance of having been joined to the cliff high above 
it ; however, admitting the bare possibility, it does not appear 
probable that the Calf could have fallen from the Cow by the 
mere force of gravitation, but I do believe that a sufficient
