The third point referred to by delegates is the danger from weevils. Practical 
experience has shown that there is less danger to be apprehended from insect 
injuries in elevators than in bags. If weevils are found in a bin orin a number of 
bins, how much more easily can the wheat be handled and cleaned ? Some people 
use formalin gas to destroy insects; some use bisulphide of carbon. Some of 
the elevators adopt this principle. If there is a disposition on the part of the 
wheat to get mouldy, it can easily be handled, aerated, and dried by being poured 
or changed from one bin to another. The wheat is aerated by the cleaning 
which it gets, and this has an excellent effect on any insect pest which may be 
present init. Another point that has been raised is the number of varieties of 
wheat grown on the Darling Downs—a fact that shows that wheat-growing on 
the Downs is,still in an experimental stage as regards the best varieties to be 
chosen. Itis a thing, moreover, that we must not allow to dominate all our 
proceedings in connection with the product of the wheat crop. If a farmer has 
400 or 500 bushels he can put it into the bins of the wayside elevator, and he 
can afterwards do what he likes with that particular wheat. The miller will 
mix all these wheats together, and if you get one or two capable men who are 
expert in discriminating between the values of the different qualities of wheats 
I think we shall arrive more rapidly than we are at which are the best kinds of 
wheat to grow in Queensland. Every form of grain can be handled by the 
elevator. You can clean, grade, and store maize in exactly the same manner as 
you can wheat, and everything I have advocated to-day in connection with 
wheat is applicable to any other form of grain. 
Mr. J. J. Danten (Pittsworth) : I may be out of order, but I have much 
pleasure in moving that we express our appreciation at the very able way in 
which this subject has been placed before us by according Mr. Thynne a very 
hearty vote of thanks. 
Mr. Daniel’s suggestion was adopted with acclamation; and the whole 
question of grain elevators was then referred, on the motion of Mr. ArKryson, 
of Danderoo, to a committee of wheat-growers to meet after the conclusion of 
the session. 
SECOND SESSION.

The first paper read was one by Mr. James Lrnpsay, of Woombye, 
entitled— 
THE FRUIT FLY. 
Those of us that follow frnitgrowing as a means of living have a great many 
foes.to battle with. We have flying foxes, numerous kinds of scale, several species 
of fungi, marsupials, fruit dep etote and last, but not least, the lively fruit fly. I 
don’t think there is any branch of the agricultural profession in which there is so 
much attention and constant battling required to keep insect pests in check as frnit- 
growing. It requires the grower to be constantly, the whole year round, looking after 
the fruit trees, to keep them at all free from fungi and scales; especially does this 
apply to the orange-grower. Then, when the fruiting season begins the fight against 
the orange bugs commences; and, lastly. when the ripening stage is coming, the nimble 
fruit fly starts on its career of destruction. » There are two kinds of the fruit fly—one 
is dark and plump, the other yellow and thin; but whatever difference there may be 
in their appearance there is no difference in their nature. Their habits are the same ; 
their methods of working through the largest number of oranges in the shortest space 
of time are similar. They both know how to choose the finest fruit and the best for 
propagating purposes as well as any fruit expert. In fact, I don’t see any difference 
in their qualities. They are both thoroughly bad, and worthy of our best attention to 
effect their destruction by every means in our power. The fruit flies are becoming 
more widespread and more numerous every year. It is only within the last five years 
that I have been troubled to any extent by the fly. Previous to that, I did not know 
what a fruit fly was, and never suffered such losses of fruit as I do now every year. 
During the season of 1900 I suffered very much by the fly, losing fully 300 cases of 
fine fruit, and last year I lost heavily. Now, the loss of 300 cases to a grower is a 
great pullback, for besides losing the fruit there is the further loss of from two to
