PLANT FORMS 



367 



Laramie unconformity, and the upper coaLbearing rocks with the post- 

 Laramie formations of this basin. When the evidence of the fossil plants 

 is thoroughly weighed this assignment, so satisfactory to the stratigra- 

 pher, may require modification.

These determinations were made more than a year ago, since which time Doctor Knowl- 

 ton has visited portions of the Raton Mesa and Canon City coal fields and collected ad- 

 ditional material, which seems to indicate that the horizons here referred to post-Laramie 

 may be of Laramie age. Pending the full study of this, together with all previous col- 

 lections, he desires to hold the matter of final settlement in abeyance.
