On the Philadelphia Turnpike, below White Horse tavern, in a 

 ditch on the west side of the road, blades of kyanite occur abun-

In digging the cellar and foundation for a barn, on a farm opposite 

 the White Horse tavern, several large boulders of kyanite were 

 found, of a beautiful blue color with blades six to eight inches in 

 length. Along the little sti'eam emptying into Darby Creek at
