No. 1209. Rain Prints. 



Pittings or depressions, made in ancient times by drops of rain on a surface 

 of clay or half-dried mud, have been found on all the aqueous deposits as far 

 back as the very earliest. They furnish us with evidence of the intensity and con- 

 tinuance of the primeval shower, and even of the quarter whence the wind blew 

 that drove them against the muddy flats of long since obliterated shores and 

 estuaries. This slab is from the Lias (?) at Turner's Falls, Mass. 



Size, 3 ft. 2 in. x 22 in. Price, $4.00. 



No. 1210. Sun Cracks and Mud "Veins. 



This slab is from the Lias (?) sandstone of the Connecticut Valley. 



Size, 26 x 17. Price, $2.50. 



No. 1211. Concretionary Cavities. 



This slab is covered with rounded polygonal cavities, arranged in somewhat 

 regular rows. They were regarded by Hitchcock as the nests of ancient tadpoles. 

 (BatracJioides nidifieans, Hk.) It is more probable that they are the result of 

 some crystallization of the ancient mud at the time of, or soon after, its deposi- 

 tion. From the Lias (?) sandstone, South Hadley, Mass. 



Size, 2 ft. 6 in. x 1 ft. 9 in. Price, $2.50.
