observation and not a little practical experience), by far the Ijetter and safer of 

 these two schemes is the Box. The Box is preferable, because the Garret, built 

 at almost any angle from the bank itself, is not unfrequently injurious, if not 

 altogether ruinous, to pools on the opposite side, as well as to ethers below on the 

 near side. Some Garrets and many Boxes, which I have in mind, have done and 

 are doing an incalculable amount of good to landlords and tenants alike. 

 Those which I have recently made here are put in singularly suitable quarters, and 

 require no more than one snow-water flood to ensure a couple of high-water 

 catches, perhaps second to none for sport on the whole estate. 



"The way I usually make a Box is easily described. In shape it is a sort of 

 triangle, and, as I suppose the whole world knows, the Box faces upstream. The 

 two sides are constructed of 12 ft. planks, 2 in. thick, measuring 11 in. at the 

 broad and 9 in. at the narrow end, so that the height -of the Box in front is 

 2 ft. 3 in., and at the back 2 ft. 9 in. The back boards are of similar material, 

 but not tapered. There is a post at front, and one at each corner at back. 

 These posts, 7 in. in diameter, and pointed, are 5 ft. 6 in. in length, so that when 

 the top part of them damaged in driving is sawn off, they will be at the height 

 desired. Good, strong old larch is a serviceable wood. The one in front is the 

 first to fix. It is driven into the gravel pretty much as far as it will go say. a 

 little over 2 ft. When this is done, it is advisable first to place the other t\vi> 

 into position, and take a close inspection from a point well above or well below, 

 in order to decide that the Box shall ultimately face straight with the stream. 

 Perhaps it should here be said that the whole of the materials ought to be at hand 

 before operations begin. The river, for instance, may rise too soon for one's 

 liking, and level unprotected work to the ground. Apart from the materials 

 quoted above, all that is required is comprised in the following list, viz., five 4 in. 

 posts, a plank, 8 in. wide, 2 in. thick ; a 2 ft. 4 in. strip of iron sheeting, 8 in. 

 wide, having holes drilled on both sides at every 3 in. ; three other iron strips. 

 2 ft. 6 in. long, 3 in. broad, drilled in the same way ; and about fifteen tons of 

 boulders, together with some smaller stones to pack them all firmly in the Box 

 le\el with the top. Some Boxes are required to be higher. 



" Before fixing the side planks to the strong front and back posts, the gravel 

 should be somewhat levelled for the edge of the bottom board to rest fairly 

 flush on the river bed, and the planks themselves bevelled off at their inner end 

 edges so as to leave them when nailed together in front with a head-end or nose, 

 s;iy, not more than a, thickness of 4 in. Of course, these are fixed as closely 

 as they will go at the front of the head post. The other end of the planks 

 may temporarily extend a trifle beyond the back posts, and be sawn off flush 

 .at a later stage. The side boards, resting upon each other, are nailed with 

 5i in. nails. When they are fixed, the tail boarding commences. But thesr 

 latter planks are nailed to the front of the back posts, so as to provide extra 

 support : they are also bevelled at the two ends, so as to fit in tight. Tin-
