we were ready to note and collect anything of interest. 



We climbed a ridge above Eagle Rock and followed 

 a trail which allowed us a view of both slopes as we 

 traveled. It was very interesting to note the influence 

 of the slope upon the ecology of the range, north and 

 north-east slopes having usually a much heavier and 

 greener growth of chaparral than the south and south- 

 west slopes. The growth on the dry sunny slopes con- 

 sists largely of Lotus glaber (Torr.) Greene and Pentste- 

 mon spectabilis Thurb., which latter occurred in such 

 dense patches as to give a purple hue to quite large 

 areas. On the more shaded slopes Adenostoma fascicu- 

 laium H. & A., one or two species of scrub oaks, and 

 the black and white sages formed the prevailing cover. 



As Prof. Fitzpatrick is recently here from the East, 

 the whole flora of the range was of great interest to him, 

 but I was intent on finding ferns. After going up hill 

 and down for about five hours, with frequent stops to 

 gather some plant of more than usual interest, we 

 spied a likely looking canyon and cast about for a way 

 of getting down into it. As there seemed to be no 

 trail we broke our way through the brush and soon 

 arrived at the bottom. The canyon was deep and nar- 

 row where we entered it, and densely filled with brush 

 which at the bottom was bound together with trailing 

 vines of Rubus sp. and Rhus diversiloba T. & G. 



On arriving at the bottom of the canyon w r e at once 

 found some beautiful fronds of Nephrodhmi rigidum 

 var. argutum, but they were sterile. However, we 

 later found plenty which were in fine fruit. At this 

 place we also found some of our beautiful gold back 

 fern, Gymnogramma triangularis Kaulf. From this 

 point travel became exceedingly difficult. At times we 

 had to crawl under the brush and vines in the V-shaped 

 bottom of the ravine, for at this place it was hardly 

 more, and at other times we had to climb up the side
