cotyledon and seeds with two, seeds whose cotyledons were raised 
above the soil and seeds whose cotyledons remained below the soil, 
seeds sending out tap roots and seeds with fibrous rootlets. 
Small sheets of glass and seeds were supplied the students 1 in 4 
order that each might make some experiments at home. One 
result of these home experiments was reported, that has a peculiar 
interest and that illustrates the inherent possibilities of Nature 
Study, A middle-aged businessman who saw a student’s experi- 
ments, became so fascinated that he began work for himself and 
was still carrying on his studies with seeds when the Summer 
School closed. 
Every lesson in Botany was illustrated as far as possible with 
lantern slides. The students were unanimous in their opinion that 
these were of great service in making clear the lectures. Some- 
times not more than three or four slides were used during a lesson. 
The educational value of lantern slides with either children or 
adults is often inversely proportional to the number used. 
An interesting lecture was given by Dr. H. M. Ami on ferns. 
The lesson was introduced by a reference to the classification of 
ferns illustrated by beautiful specimens. Dr. Ami then gave the 
students an opportunity to examine the reproductive organs of { 
ferns under a high-power microscope. 
An inspiring address was given by Prof. Robertson on the 
Manual Training and Nature Study Schools organized under the 
Macdonald Fund. Several students determined to take a thorough 
course in Nature Study when the College at Ste. Anne de Bellevue 
shall be ready to give them a welcome. 
A very profitable lecture was given by Prof. Prince, of the 
Fisheries Department, on Fish Life. It was superbly illus- 
trated and delivered in a most pleasing manner by a man who has 
given the greater part of his life to this one subject, and whose 
opportunities for studying fish habits have been unrivalled. 
_ On the whole, although a course of three weeks has many — 
limitations, it has some possibilities. The chief of these is the 
giving of an intelligent and rational insviration. 4

The great success of the Ottawa Summer School this year 
was undcubtedly due to the great care with which all arrangements 
were made by Dr. White and Mr. Putman, not only for the in- 
struction of the visitors but for their comfort in every way. All ~ 
in attendance felt that. The constant patience and courtesy of — 
these gentlemen and of Mr. Attwood, as well as the vast amount 
of useful and helpful knowledge imparted, made what was un- — 
doubtedly a period of hard work also a pleasant holiday.—NATURE /
