180 MESOZOIC FLORAS OF UNITED STATES. 



Mention was made in the first paper (p. 387) of a collection that had 

 been made by Mr. Charles Gilmore before my arrival. This, I was told, 

 was stored in a building in Medicine Bow, but as our party hurried through 

 that place to reach the field, I did not take time to hunt it up and examine 

 it. It was expected that an effort would be made to increase the collec- 

 tions by plowing the ground deepty with a subsoil plow, as might easily be 

 done. I had dug out a number of fine trunks with my mattock that were 

 not visible from the surface, but this process was slow and laborious, and 

 it was thought that such subsoil plowing might reveal manj'- more. 



At the close of 1902 I learned from Professor Knight that the Uni- 

 versity of Wyoming had arranged with the Carnegie Museum to plow the 

 ground on which the cycads were found and divide the results between 

 the two institutions, but that the degree of success was not what had been 

 anticipated. Professor Knight stated that before the ground was plowed 

 he had found ' ' one of the finest specimens that has ever been taken from 

 the place. ' ' This I have not yet seen. He sent me, however, as one of 

 the results of the plowing, a fine terminal bud, which he thought might 

 be a cone. As nearly as I can judge, it belongs to Cycadella jurassica, and 

 at his suggestion I have given it the next number of the museum of the 

 University of Wyoming, first series, which is 500.688. 



On March 20, 1903, Dr. T. W. Stanton turned over to me a specimen 

 collected by W. T. Lee from the same bed in the Freezeout Hills. It is a 

 small fragment from the side of a large trunk showing half a dozen large 

 scars that indicate that the trunk was that of Cycadella wyoyningensis. 

 It is deposited in the National Museum with the locality number, 3050, of 

 the United States Geological Survey. 



During the summer of 1901 a third invoice arrived, purporting to 

 contain all the specimens collected to that date. The larger trunks, at 

 least, are doubtless the ones previously collected by Mr. Gilmore, but 

 nearly all the specimens in this invoice are fair-sized fragments, and there 

 are very few small pieces, such as many that I saved. 



This last collection was numbered before it was shipped and on a 

 different basis. It bears the numbers of the Museum of the University of 

 Wyoming from No. 100.201 to No. 100.353, thus containing 153 specimens. 

 There are, therefore, in the additional material to be studied 753 speci- 

 mens, great and small. Yet in all this there are not a dozen trunks that
