MUSEUM LECTURES 
Among the most important educational activities of the National 
Museum is the series of illustrated lectures given under the auspices of the 
Museum in the Museum lecture hall. 
The lectures are given on Saturday mornings for children and are 
repeated on Wednesday evenings for adults. They embrace animal and 
plant life, the life of the aborigines, natural resources, industries, geography, 
travel, and related subjects, and each is given by a lecturer from his own 
experience. The Saturday lectures for children are supplementary to school 
work in geography and nature study. They are limited to less than forty- 
five minutes, are illustrated by specimens or lantern views, and are fol- 
lowed by motion pictures, the whole period not exceeding one hour. 
It is hoped that these lectures may be suggestive to the children of sub- 
jects of intensive study and may inspire them to become in adult life work- 
ers in, or supporters of, the scientific and cultural activities of the nation. 
The Saturday children's lectures were announced for both ten and 
eleven o'clock. On many occasions the lecture hall did not accommodate 
the crowds and a third lecture was given to the overflow. 
For adults the same subjects as presented to the children were treated 
at greater length. These evening lectures likewise often taxed the seating 
capacity of the lecture hall, and on some occasions a number of people were 
unable to obtain seats. The large and well sustained attendance, con- 
sidering adverse weather conditions, at both the lectures to children and 
those to adults, proves that this educational effort of the Museum is appre- 
ciated. Fourteen illustrated lectures w r ere given during the season of 1933- 
34, divided into a first series beginning November 18 and ending December 
16, and a second series beginning January 6 and ending March 7. 
Many of the lecturers are in the service of various Government depart- 
ments, and others are prominent in industry and the professions. All gave 
their time and skill for this public service without compensation other than 
the satisfaction of diffusing the knowledge they have gained. The Lecture 
Committee takes this opportunity to thank them most heartily for their 
cordial co-operation. 
The Boy Scouts Association of the Ottawa district has provided ushers 
at the children’s lectures on Saturday mornings, an assistance greatly appre- 
ciated by the Lecture Committee, especially as it tends to make the children 
feel that Saturday morning at the Museum is a youthful occasion and to 
develop in them a spirit of co-operation and responsibility.

Committee acknowledge the courtesy of the following: Cunard Steamship
