rainfall or to the drainage of any waste water or liquid 
refuse. 
Earth-closets with a movable receptacle, such as a 
galvanised pail, may be constructed in connection with a 
dwelling-house, but not within the same, in such a manner 
and position as previously described. The capacity of the 
movable receptable should, however, be limited in order to 
ensure the removal of its contents at least once a week. The 
seat or riser should be adjusted to admit readily of the 
removal of the pail. A small ledged door and frame in the 
back or side external wall may be provided for this purpose. 
Building Materials. — A good deal of prominence has been 
given to the use of concrete blocks, and, where the site 
itself provides ample gravel and sand, and neither bricks nor 
stone can be obtained without the expense of cartage for a 
considerable distance, it is possible to build more cheaply 
in this manner. On the other hand, where bricks can be 
had at a moderate price, it is doubtful whether much saving 
can be effected by the use of these blocks. In any case, it is 
of paramount importance that the manufacture of concrete 
blocks should be carried out under skilled supervision ; the 
quality of the cement, the proportion of the constituent parts, 
the mode of mixing, &c, being details requiring the greatest 
care in order to ensure satisfactory results. 
In districts where stone is plentiful and available for 
building purposes, it Is necessary to ascertain that its 
weathering qualities are such as would justify its use for 
this purpose. Where gravel and sand can be obtained on 
the site, care should be taken to see that they are free from 
all earthy or clayey matter before use, and that the sand is 
sufficiently sharp. 
Bricks can still be obtained at very reasonable rates in 
many districts, and for general work, good, sound, hard, 
well-burnt bricks from approved yards should be used. For 
external facings they should be of uniform shape and colour, 
but for internal use thoroughly sound work can be obtained 
by the use of "Flettons," which can be procured in truck- 
loads at a low rate. The main objections to their use for 
external work are their unevenness of colour, and their 
liability to flake in much exposed situations, while for internal
