GEOLOGY, 



Lincolnshire Boulders. — Mr. C. B. Parker, Irby, has 

 furnished me with chippings and particulars of the following 

 boulders : — 



1. Carrock Fell Gabbro.'''" 2 ft. i in. x i ft. x 10 in. Nearly 



half a mile south of Irby-on-Humber Church. 



2. Whin Sill. 2 ft. 4 in. x i ft. 6 in. x i ft. 5 in. Seven fur- 



longs south of Irby-on-Humber Church. A groove 

 about seven inches wide and one inch deep, and extend- 

 ing the full length, occurs in this boulder, suggesting 

 , :■ that for some time this stone was fixed, and the groove 

 ; ; -worn by other passing boulders. 

 The first was turned up by the plough, November 1904, and 

 the second December 1902. Both occurred above the 200-ft. 

 contour line. I enclose chippings. — A. Smith, Grimsby. 



* This appears to be the first record of this rock for the county. — Eds.
