It would take hours for me to give you even a brief account of 
the many advantages to be gained by a study of economic insects, 
as the subject is not only interesting and useful, but also well 
nigh endless. I can, however, promise you that should the 
Department so desire it, and your instructors think fit to ask for 
another discourse on these lines, I will be most willing to place 
my humble efforts at your disposal. : : ; 
As the days are now short, and the daylight is fast passing 
away, I must conclude by saying that to be successful we must be 
practical as well as energetic, always willing to learn from those 
who are willing to impart their knowledge to those requiring it, 
and never ‘setting ourselves up” as knowing everything, as we 
can learn something from the humblest. In these days of busile, 
turmoil, and keen competition, it behoves every one of us to be 
on the alert, and the grower who is able to discriminate between 
his insect enemies and friends must surely have a better chance 
than those who know nothing of the subject. As for botany, 
what shall I say of it? Nothing further than to remark that the 
same rule which applies to the use of a study of entomology will 
apply, as our friends Baron von Mueller and Mr. McAlpine can 
tell you better than I can, to botany ; not forgetting chemistry, 
which is probably the most valuable of all the applied sciences. 
If I were asked whether I would prefer the study of botany to 
that of entomology, I feel sure, from previous experiences, I 
should reply that I weuld prefer to study both. Do not, when 
you have gained a little scientific knowledge, look with a superior 
sort of air upon the practical orchardist, as he, having better 
chances often of observation in orchards than you may have, will 
be able to teach you many a practical lesson which may serve 
you in good stead. The time is upon us when we must use our 
heads as well as our hands, and the end of all this will probably 
be, as the great Darwin has told us, the survival of the fittest.
