Foreman Gardener, have done most of this work, one of 
them having been available at all times to escort parties of 
children or adults to parts of the grounds and buildings, 
explain the collections and answer questions; all other 
members of the staff have, however, participated in such 
instruction, which is very effective and highly appreciated. 
The correspondence of the institution in replying to 
requests for information about plants of all kinds and plant 
products continues to be very extensive. 
Details of this work may be found in the report of the 
Supervisor of Public Instruction hereto appended. 
Instruction of convalescent soldiers in practical garden- 
ing, commenced early in I919, was continued, with a 
decreasing number of students, until November, when 
our arrangements with the Federal Board for Vocational 
Education were terminated. During the time of this work 
84 convalescent soldiers were given instruction for longer 
or shorter periods. A few of them developed fondness for 
gardening, but the great majority did not, and these will 
probably be more useful in other occupations. Those who 
appear to be likely to take advantage of their opportunities 
have been permitted to remain as apprentices. All these 
students were greatly benefited in health while at the 
Garden, and this was, perhaps, the most important result 
to be obtained. 
A few civilians have been enrolled as gardening students 
and have done good work, but it would appear that the 
establishment of an apprentice system with remuneration 
is the more likely to be satisfactory. 
We are continuing the position of Supervisor of Garden- 
ing Instruction into 1921, however; Mr. Boynton’s de- 
tailed report on instruction given during 1920 is hereto 
appended.
