CONTINUATION OF BOTANICAL STUDIES 45 



cold water accounted for the change in flora on its shores. Later 

 on in these notes I will speak of what this led to. 



Many of the species I found on this trip were rare and a 

 number new to science. Mr. C. F. Austin named the mosses and 

 hepaticas and named one of them Jungermannia Wattiana. The 

 lichens I sent to Professor Tuckerman and found him a gentleman 

 and a friend in need. Until his death he named every one of my 

 lichens. But what was most valuable to me was that he presented 

 me with all his works and assisted me in many other ways. When 

 I look back at this early time, I found that every specialist helped 

 me in every way they could and I was now, thanks to them, on 

 my feet and could do my own thinking without the aid of a master. 

 The more I read the less I believed in many notions that prevailed 

 about climatology, but had no knowledge to contradict them. 



I decided to spend part of my vacation this year (1870) in 

 North Hastings about 50 miles north of Belleville. I took a 

 companion, one of my pupils, and we spent two or three weeks 

 amongst the lakes and streams of that region. No difference was 

 found in the general flora except one that I had noted before, 

 namely that the Laurentian rocks produced generally a distinct 

 flora from that of the limestone. I considered the plants on 

 limestone lands as showing a warmer climate than the Laurentian. 

 I would say now that the soils were warmer and more southern 

 forms were to be seen. 



The year 1871 opened with an invitation to spend my holi- 

 days at Royston Park near Owen Sound, and I gladly accepted, 

 as I wished to visit Lake Huron. Mrs. Roy was an accomplished 

 botanist and corresponded with all the leading Scotch botanists. 

 Besides, she knew where most of the species, for which Owen Sound 

 was famous, grew. July of that year saw me a guest at Royston 

 Park, and for the first time having communion with a botanist 

 day after day. Mr. Roy called himself our man Friday and 

 carried a basket. We collected many mosses and flowering plants, 

 the former of which were sent to Professor James, who was then 

 preparing his Manual of North American Mosses. The ferns of 

 that region were fine and a number of species were collected in 

 quantity.
