mill over the rapids, after which the Phosphate CrLishiug Works were 

 visited. The Excursionists received every attention from Mr. Taylor, 

 who, in the absence of the Manager, showed them over the mill and 

 explained the machinery by which the raw material is crushed and 

 prepared for the manufacture of super-phosphate. There were in the 

 mill over 150 tons of ground phosphate (finer than wheat flour) ready for 

 shipment. Having returned to the whai-f the usual elementary lectures 

 were delivered by the leaders. Mr. Fletcher was first called upon by 

 the President to speak on Entomology. He stated that rare insects 

 had been collected, and announced the capture of a female of Colia& 

 Interior, a very rare butterfly, and one he v/as particularly anxious to 

 breed from the egg. His remarks were directed towards showing the 

 advantages which are to be derived from students working out the life- 

 histories of difi'erent species of insects, and showed that it was one of 

 the most important factors in the success of Economic Entomologists. 

 Mr. Henry M. Ami then explained ihe difi'erent rock-formations 

 which wore to be seen in the locality. The Laurentian and Potsdam 

 formations were the two which occurred of the older Geologic Epochs 

 at Buckingham. In the former were found inexhaustible supplies of 

 iron, apatite or phosphate of lime, plumbago, mica, baryta and other 

 mineral products, and the Potsdam formation afforded building 

 materials of first quality. Mr. Ami then drew attention to the traces 

 of glaciation which were well exposed in several places and gave a 

 succinct and lucid account of the Great Ice Age. The President, Mr. 

 Pt. B. Whyte, gave the address upon the Botanical specimens collected, 

 he said the locality was an exceptionally rich one as was evidenced 

 by the many rarities which had rewarded the collectors. Mr. Whyte 

 took advantage of some of the familiar plants to explain in a clear and 

 attractive manner a few of the rudiments of structural botany. He 

 used the Nymi^hcea tuherosa to show the gradation of all the floral 

 organs from the leaf-form. Impatiens fulva, the common balsam or 

 "Jewel Weed" of our swamps, was exhibited and everyone was advised 

 to take special notice of it, as it was reputed to be the antidote for the 

 Poison Ivy [Rhus toxicodendron). Many other rare and beautiful 

 plants were spoken of and made interesting by the remarks of the 

 speaker. The party reached the city again about 9 o'clock, when the
