solution of one part of bi-chloride of mercury to i,ooo parts 

 of water. This will d,estroy all spores of mould, but care must 

 be used in handling the solution on account of its being a very 

 deadly poison. Many of the importers in Great Britain say that 

 a little blue mould is not objectionable, providing the cheese 

 has a perf^ect skin so that the mould will not penetrate. If the 

 cheese get very mouldy in a curing room, however, they are 

 apt to be very bad by the time they reach England. 



SOME SUGGESTIONS FOR IMPROVING CURING ROOMS. 



There is so much diversity of construction in existing build- 

 ings that no instructions can be given for their improvement 

 except in a general way. The ice chamber should be from one- 

 quarter to one-third the size in cubic capacity of the curing room, 

 according to the efficiency of the insulation used. Many of the 

 factory curing rooms are large enough to allow of the ice cham- 

 ber being built inside the present walls of that room. The first 

 thing to do is to put a stone or concrete foundation wall under 

 the building, then lay a cement concrete floor over the area of 

 the curing room, and plaster the foundation walls on the inside 

 with cement to give them the same finish as the floor. 



The walls of the curing room should not have less than two 

 thicknesses of matched lumber and two ply of good quality 

 building paper both inside and outside of the studs. The spaces 

 between the studs should be filled with planing mill shavings ; 

 otherwise more lumber will be required in the walls. In altering 

 seme old buildings it may not be possible to fill the spaces be- 

 tween the studding with shavings. In such cases the best plan 

 is to set up light studs inside the present wall and finish with 

 two thicknesses of matched lumber with two ply of building paper 

 betvyeen. These studs should be placed so as to leave a space 

 for filling with shavings of not less than 6 inches between the 

 new sheathing and the old. It will be all the better if the 

 new studding stands clear of the old sheathing. 



The ceiling of the curing room should have two thicknesses 

 of matched lumber and two ply of building paper under the 

 joists,, and at least one thickness of matched lumber on the upper 

 side. The spaces between joists should also be filled with shav- 

 ings. 



Double windows, with tight-fitting sash, each double-glazed, 

 are necessary. Windows should be as small as possible and 

 placed at ceiling of the room. 



The door of the curing room should be of the refrigerator 

 style, fitted into a beveled frame.
