although the known examples have mostly been found in one quarry 

 (Mr. Hill's) ; I think, however, that this is chiefly attributable to 

 the fact that the intelligent quarryman, Mr. Lomax, preserves and 

 dispenses to geologists all the fossils which he obtains. I have one 

 good specimen of this peculiarly local fossil, found in the Lincoln- 

 shire Limestone at Denton, near Grantham (to which I shall pre- 

 sently allude) ; it occurs also in the shelly beds at Ponton, and I 

 have already mentioned one other obtained by Mr. Judd from Mor- 

 cot : but I believe it has not been detected in any other locality. 

 On some of the slates, peculiar large worm-tracks are found.

The Collyweston Slate is now very much in request for roofing 

 either restored or new buildings in Mediaeval styles. It assorts 

 well with such buildings ; and, while fresh, is very eyeable. When 

 the material and the workmanship are both of the best, it is toler- 

 ably durable ; but if the slates are not picked, and if the work- 

 manship is not better than ordinary, the roofs soon become dilapi- 

 dated, ugly inequalities appear, the wind and the rain penetrate, 

 and a slate roof then is neither sightly, efficient, nor lasting. 



Sir Gilbert Scott has used this slate in his exquisite restoration of 

 the beautiful Round Church at Northampton, and also for the roof
