some of considerable size. The indurated clay of the higher or second 

 exposure, No. 2, is yellowish or buff in color and has an entirel)' different 

 arrangement, being more sharpl}^ distinct from the inclosing sand. 



This locality was discovered by Professor Ward on April 16, 1893 

 (for full details see pp. 382-383), and the principal collection, espe- 

 cially from the lower lignite bed, was made at that time. On July 17 

 of the same year Professor Ward took me to the place and we made a 

 small collection, chiefly from the upper bed, which was then in a good 

 condition for working out the impressions. The collection made bj^ us 

 from this bed at that time is larger and better than that made at the 

 earlier date. Only four specimens were taken on this occasion from the 

 lower bed, and therefore in the treatment of the flora of that bed it will 

 be assumed that all the specimens belong to the earlier collection except 

 where it is stated that they occur in the later one.
