living, and, besides a large number of dried specimens, bringing 

 back floral descriptions and other records of field observations. 

 Based primarily on this field work, but extended to include the 

 revision of most extant herbarium material from the states of 

 Colorado, Utah, Wyoming and from southeastern Idaho, a 

 summary of our knowledge of the species of Pentstemons within 

 those states has been attempted. 84 species are now recognized, 

 grouped in 19 sections. Specimens of all the species represented 

 in the Garden herbarium, were shown and points of taxonomic 

 affinity or range were discussed. This revision is to appear in 

 the Bulletin of the Club." 

 Adjournment followed.

The meeting was held in Schermerhorn Hall, Columbia Uni- 

 versity, at 8:15 P.M. President Richards presided. There were 

 35 persons present. 



The regular order of business was dispensed with. 



The lecture of the evening was given by Mr. Louis Schmidt, 

 Rockefeller Institute for Medical Research, on "Methods of 

 Modern Illustration." Mr. Schmidt gave a brief outline of the 

 history of the various methods used in illustration, such as wood 

 engraving, steel engraving, etching and lithographing. 



Owing to the considerable expense incurred in connection with 

 many of these processes, they have been largely superseded by 

 such methods as the half-tone process, zinc etching, photo- 

 lithography, and photograveur. The speaker emphasized the 

 point that the modern processes, while much cheaper, failed to 

 reach the degree of excellence to be obtained by the older 

 processes of lithography. The four-color process of making 

 illustrations was described in some detail. The lecture was 

 illustrated with many examples of work done by these methods. 

 Lantern and epidiascope were used during the evening. 



Meeting adjourned.
