270 ORGANIC REMAINS. 



one, approaching to the size of the one figured, was discovered within 

 these two years at Bridlington Quay. The latter has the roots pretty 

 entire, and shews thirteen plates on the masticating surface. — Part of 

 an elephant's tusk, eighteen inches long, and five in diameter at the 

 broadest end, was taken out of the alluvial cliff near Scarborough 

 spaw, some years ago. Similar fragments have been found at Brid- 

 lington and other places. 



But the chief repository for the bones and teeth of quadrupeds 

 in our district, is a cavern in the oolite, recently opened at Kirkdale 

 near Kirkby Moorside ; and we feel much pleasure in being able to 

 gratify our readers with an account of this interesting spot. 



We have already noticed ( p. 68, 69) the caverns and fissures in 

 the limestone about Kirkdale. Among the places where we had 

 seen vestiges of fissures was the quai-ry on the side of the road, a 

 little to the south-east of Kirkdale church. This quarry, which is 

 wrought chiefly to procure stone for repairing roads, fronts the south 

 or south-west, and is in the upper part of the eastern bank of Hodge 

 beck, the stream that flows past Kirkdale church. Here the oolite 

 strata gently dip towards the south, till they sink under the alluvial 

 plain, less than a quarter of a mile to the south of this spot; and 

 hence the banks of the stream, which are lofty at some distance above 

 Kirkdale, are here scarcely higher than fifty or sixty feet. They 

 present the same steep but smooth slopes as we find in the northern 

 fronts of the oolite hills (see p. 64), the broken edges of the strata 

 being covered with the alluvial soil, in which trees are here growing. 

 The oolite at the quarry is of a hard quality, especially where it ac- 

 quires a blueish colour ; passing into a kind of blue or grey limestone, 

 that is only imperfectly oolitic. We may here take occasion to intro- 

 duce a remark, which should have been made before; that this blue 

 and grey limestone, which we stated to occur usually under the oolite 

 (p. 71, &c. ), is often found in patches in the oolite, at a considerable
