The destruction of Castle Rocks, now seemingly inevitable, 

 is cause for the expression of just indignation. The historic 

 and legendary' associations of the spot are many, and these 

 should have been sufficient to preser^^e it from such violation. 

 The rocks composing the group are without rival in south- 

 eastern Penns3'lvania as an example of the rare mineral ensta- 

 tite on a grand scale. As such they have been visited by 

 geologists from many sections and have served most admirably 

 for the elucidation of certain geological and petrological prob- 

 lems. That considerations of this order should be outweighed 

 b}' petty financial interests is lamentable enough. 



A number of members of the Institute have been much 

 interested in silk worms of late. They report that when spin- 

 ning time came one of the worms, after several unsuccessful 

 attempts to spin, went into the pupa state without making a 

 cocoon and in about two weeks came out a fully developed 

 moth. The steps in the process were watched with much 

 interest. It is rather remarkable that although this worm had 

 made no cocoon, nevertheless toward the end of the pupa 

 period it secreted a yellow liquid, apparently the same as is 

 used by the normal moths to soften the silk in order to escape 

 from the cocoon. 



The plates in this issue of the Proceedings were made by 

 the Photo-Chromotype Engraving Company and printed by 

 Harris & Partridge, all of Philadelphia. They certainly deserve 

 credit for the work. 



" Whatever is, is right," — a saying that would be all ven,' 

 well did it not cany with it the inevitable implication that 

 nothing that ever was, was wrong. — J. B. B.
