board should be cut eleven inches wide 
by twenty inches long, also several 
sheets of heavy blotting paper and mus- 
lin cloth cut to the same dimensions. The 
first layer to put in the box is a sheet 
of the strawboard, Z, on No. 3. Over 
this the blotter sheet, X, is located as 
shown. Then the prints are placed next 
and their position is labeled N, while 
over the prints, which have been placed 
in the dryer face up, a strip of the mus- 
lin cloth, M, is placed. Then another 
layer may be placed over the muslin and 
the series built up again as described. 
This operation is continued until all the 
prints are in the dryer. Then the part, 
K-H, is located in place on top of the 
contents of the body and the electric 
fan started directly in front. The cur- 
rents of air will pass through the cor- 
rugations of the strawboard and quickly 
take away the moisture that has been 
absorbed from the prints by the blotting 
paper. In ten to twenty minutes the 
prints will be perfectly dry and when 
removed will lie out perfectly flat and 
smooth.

A SPORT RAFT 
A S this is the season for water sports 
it may not be out of place to de- 
scribe a diving raft that will afford much 
pleasure to build and also to use after it 
is completed. It is constructed of 2" x 
10" cypress planks and measures 6' x 14'. 
Four air tanks are used to give it buoy- 
ancy. These are made from second-hand 
kitchen boilers with all pipe fittings re- 
moved and the openings plugged air- 
tight. Fasten the boilers to the raft

by thin iron straps secured with gal- 
vanized iron bolts and screws. The div- 
ing board measures 2" x 12" and is 12' 
long. The frame to hold it in place is 
made of 2 pieces of 2%" x 6" channel 
iron (Carnegie C108) and 2 pieces of 
3" x 5" angle iron (Carnegie A196), 20" 
long and bolted to the board as shown in 
cut. Drill 1" holes through all 4 pieces 
and run a bolt through them and fasten 
securely with washer and nut. Cover 
the end of the board with best quality, 
standard corrugated rubber matting 
nailed on with copper tacks %" long. 
Purchase a second-hand coil spring of 
good tension and insert it as shown in 
cut. The diving board should exert a 
slight tension on the spring when it is 
down against the bumper. The entire 
float should not cost more than $100.00 
if care is exercised in purchasing good

second-hand material. An anchor and a 
hold-fast cleat should be provided at one 
end of the raft to hold it in position. 
If you wish to change the location of 
the float just pull up the anchor and 
tow to wherever you wish. The whole

the pleasure of diving and will be the

of water sports.
