Two sets of receptacles should be provided. While one set is be-

THE L. R. S. PRIVY.* 
On account of the various objections raised against the different 
styles of privies now in use, an effort has been made to construct a 
device which will decrease the disadvantages and at the same time 
increase the advantages connected with the older types of outhouses. 
The results ob- 
tained from various j 
experiments have 
been applied to an 
apparatus known as 
the L. R. S. privy 
(figs. 8, 4, and 5). 
This apparatus

barrel or other con-

(3) A connecting 
pipe about 23 inches 
in diameter, about 
12 inches long, and 
provided with an open T at one end, both openings of the T being 
covered with wire screens. _ 
(4) A tight box, preferably zinc lined, which fits tightly on the top 
of the liquefying barrel. It is provided with an opening on top for 
the seat, which has an automatically closing lid. 
(5) An antisplashing device consisting of a small board placed 
horizontally under the seat about an inch below the level of the 
transverse connecting pipe; it is held in place by a rod, which passes 
through eyes or rings fastened to the box, and by which the board is
