On Saturday evening, May 17, 1902, the Society held a 
highly successful Scientific Assembly. From 5 to 7 p. m. 
officers of the Society conducted parties through the Garden 
and greenhouses of the University. Lunch supper was then 
served in the Botanical Library Hall. 
At 7.45 Provost Harrison, Honorary President of the

coniferous and included the tideland spruce, Douglas fir, 
western hemlock and red cedar. Some three hundred species 
of plants were found in this region. Returning via Idaho, 
a stop was made to collect Nymphea Leibergu, which was 
successfully located in a small pond of that State. 
Miss Marion Mackenzie next spoke on “Recent Investi-
