64 How to obtain it. 
tion, it is often desirable to make the outlet as near the south-west 
corner as practicable. Our prevailing wind being south-west, and 
most of our heavy gales coming from that quarter, it will be 
apparent that the effect of the wind will be to keep the south- 
west corner clear of floating matter. When the outlet is in the 
opposite corner, all the floating matter is driven right on to the 
screen, and causes much extra trouble. In some cases the situation 
of the outlet in a rather bad position as regards the wind is almost 
unavoidable, but in a great many instances it is quite a simple 
matter to arrange it on either the southern or western side of a 
pond. Of course some ponds are sheltered on the south-west, 
and exposed to east winds, and work best with the outlet on the 
east side. It is therefore necessary to take the bearings and study 
the peculiar circumstances surrounding each case, and then decide 
on the best place in which to construct an outlet. The result may 
perhaps be that the best position for it, as regards wind, may 
prove to be on the same side or very near the place at which the 
water enters. This, again, is not good, and it may be desirable to 
convey it, by means of a raceway, round to the opposite side, and 
turn it in there, so as to make sure that it runs completely through 
the pond. This may often be easily done, and is an advantage, 
inasmuch as it provides an extra length of spawning ground for 
the fish. Or it may be done by placing the leaf screen half-way 
along the raceway DD (see Fig. 1) instead of at the point C or D. 
So much, then, for the position of the outlet. 
Here let me say that the east wind is sometimes as bad for 
fish as it is for man and beast. It has been found that under 
some circumstances fish are adversely affected by it. This is one 
of the many points that require investigating, and every scrap of 
information that can be gathered together will tend to teach us 
something more about that of which we know comparatively little 
at present. We do know that in laying out fish ponds for profit, 
which are necessarily small and heavily stocked with fish, the east 
wind is a factor which has not to be overlooked. 
Having considered the position of the outlet, we have now 
to decide which is the best way to make one—one that can be relied 
upon ‘to work in all weathers, with the least possible attention or 
care on the part of an attendant. That care must be given to an
