maintained than with the aid of the cocoanut-fibre refuse alone. Besides, 
there is less risk of the air becoming too dry when hot water is employed. 
The material required to construct this propagator will be twenty-five feet of 
seven by one-inch matchboarding, two feet of sash bar similar to Fig. 6, and 
fifteen feet of one by one-inch deal. In proceeding to construct the 
propagator, first cut off four eighteen-inch and four twenty-inch lengths of the 
matchboarding, and join two of each size together to make a bottomless box 
(Fig. 7), the inside measurement of which will be eighteen by eighteen inches, 
and put some of the one by one inch wood in the corners, in order to 
strengthen it. All the tongues of the wood must be kept the same way up. 
Now take the eighteen by eighteen-inch case with the tongue side upwards 
U 
Fig. 6. 
and cut the tongues off with a spokeshave or plane. Next get a piece of 
finely perforated zinc, and nail it tightly across the bottom of the case, on the 
groove side of the match boards (as shown in Fig. 7), great care being 
observed that the zinc does not overlap the groove in the least degree, other¬ 
wise the tongues of the under case will not fit in properly. A small hole 
must be made on each side of the zinc, before fixing it, to admit the steam 
pipes, of which we shall speak presently. Next make an under case, the 
same as the top one, except that it must have three sides only, and the one by 
one-inch wood must not be put down the angles. 
A galvanized iron tray, 17I- by 17^ by 2^, will be necessary, and two pieces 
of iron, 18 inches long, as shown in Fig 8, will be required also, the latter
