say 18 feet wide by 30 feet in length, may be placed in 
position for .83,000. This I consider the most suitable 
where there is only bateau traffic, as a sliding could be 
made for hauling over, similar to what is placed at the 
west side of Tapacooma. 
To those wishing to gain more experience on these 
heads, I recommend a visit to the very fine lock, on the 
caisson principle, which connects Pin. Anna Regina with 
the Tapacooma Lake. For lock sluices, I would mention 
those placed at Vreed-en-Hoop, Windsor Forest, 
Leonora, Uitvlugt, &c, &c. And for a barrage with 
simple lifting panels, I would name the one placed in

from Skeldon to Capoey, and the cost, if borne by the 
general tax-payer, would be such a trifle as compared 
with the benefits of cheap and wholesome flesh diet, that 
I trust another decade will not roll past without its 
accomplishment. 
A writer in the Argosy has lately described a novel 
and very excellent way of cheap dam-making. I take 
the liberty of reproducing the article : — 
Beaver Dams. — In connection with the Water supply question a 
new name has sprung up in connection with dam making ; and being 
of an enquiring turn of mind I set a day apart to paj 7 a visit to the 
Boerasirie, where I was informed, " Beavers" were at work in dam 
making. On arriving at the stop-off on the creek, I found a gang of 
men at work assorting saplings of bush and grass in a cradle or frame-
