244 T^HE Ottawa Naturalist. [March 



Prof. Penhallow's lecture on '* The Wood-pulp Industry in 

 Canada," in the Normal School, Jan. 13th, attracted a lirge num- 

 ber of lumbermen and others interested in the manufacture of 

 pulp and paper, and there was the usual large attendance of 

 Normal School students and members of the Club. The lecture 

 was illustrated by many beautiful lantern slides showing the 

 many varieties ol pulp that had been used in the manufacture of 

 paper from the earliest times to the present. The manner in which 

 the ancient papyrus and the felted Japanese papers are made was 

 clearly explained. The greater part of the lecture was devoted 

 to describing the various processes employed to-day in manufac- 

 turing pulp and paper from the products of the forest From the 

 cutting of the trees in the forest to the turning out of the finest 

 paper from the mills of the St. Maurice and Sault Sfe. Marie 

 rivers, every step of the process was illustrated by lantern slides 

 specially prepared for this lecture. 



The most timely lecture of the winter course was that de- 

 livered by Dr. S. B. Sinclair, Feb. loth, on " Nature Study in 

 American Universities." Nature Study will soon be one of the 

 chief branches taught in our public schools, and the teachers who 

 listened to Dr. Sinclair must have been impressed with its im- 

 portance. Taking Chicago, Clark and Cornell Universities as 

 typical he traced the development of the Nature Study movement 

 during the last thirty years, and said that there was now an 

 almost universal opinion in favour of a certain amount of such 

 study in every grade from the Kindergarten forward. A detailed 

 statement of the points covered by the lecturer will appear in the 

 May number of The Naturalist. The lecture was discussed by 

 Prof. Macoun and Dr. Fletcher, who endorsed all that was said 

 by Dr. Sinclair. 



The Report of the Entomological Branch was read at the 

 close of the lecture. 



On February 24th. Prof. Macoun lectured in St. John's Hall, 

 on "The Summer Climate of the Yukon and its Effects on Vege- 

 tation." After briefly referring to the route from Vancouver to 

 Skagway, and from Skagway to White Horse and so to Dawson,
