Dr. Hollick succeeded in collecting a large number of speci- 

 mens which will make valuable additions to the museum, besides 

 a large amount of lignitic material which it is hoped may yield 

 interesting results when subjected to microscopic examination. 



From June 13 to 16 Dr. Hollick was the guest of Professor 

 Jeffrey at Harvard. During this visit some of the material 

 jointly collected was subjected to preliminary examination and a 

 trip was also made to Scituate, on the shore of Massachusetts 

 Bay, where strata of undetermined age are exposed. Lignites 

 collected at this locality may assist in solving the problem. 



Dr. Hollick and Professor Jeffrey are preparing a joint con- 

 tribution upon the botanical characters of the Cretaceous flora of 

 the region, in connection with which the material recently col- 

 lected will be of great assistance.
