pores, receiving and discharging moisture, which keep them 

 cool; while woolly pubescent leaves are much warmer. An 

 Irishman once called the mullein a canton flannel ivy. Note 

 the difference of temperature between the leaves of the Clema- 

 tis paniculata, Lilium speciosum album and Physostegia as 

 compared with those of the Lychnis coronaria, Anchusa Barre- 

 lieri, Helianthus mollis, and Rudbeckia. I do not know that 

 it can be laid down down as a general rule, but it is certainly 

 true of many plants, that those with rough, woolly leaves suffer 

 more from heat and drought than those with smooth glossy 

 ones. 



Speaking of one sense supplementing another reminds me 

 of my belief that the sense of sight is next-door neighbor to the 

 sense of touch, and each sits on the other's doorstep at times 

 to receive impressions. The green foliage of the tall late cos- 

 mos and the tender green depths of a locust-tree give me the 

 same pleasurable sensation that I get when touching fur or a 

 silky velvet. I have seen square flat heads on certain people 

 that feel rough and harsh to the eye.
