DISINFESTATION 55 



after the arrival of the Mission at Nish, and the 

 following week was destroying lice wholesale. It 

 has this great advantage that any small body of 

 men may have a private disinfestor always with 

 them at a very small cost. It consists of an 

 ordinary large wine barrel (Fig. 10), in the bottom 

 of which a number of holes are bored. This is 

 placed over an open boiler (an empty paraffin 

 drum will suffice) in such a manner that the 

 steam can pass freely through the openings into 

 the barrel. A circular sand-bag piping is placed 

 between the boiler and the barrel to prevent the 

 waste of steam. A little distance above the 

 perforated baSe a wooden grid is constructed, and 

 on this the articles to be treated are placed. 

 The whole is then closed by means of a heavy 

 wooden lid which is weighted down with stones. 

 A barrel of a capacity of sixty gallons will deal 

 with four complete kits or seven blankets at a 

 time. After the steam escaping round the lid is 

 too hot to be borne by the hand an hour is allowed 

 for the thorough treatment of the load. 



Ordinary galvanised iron sanitary bins (Fig. 11) 

 were also used in Serbia. A foot of water with 

 an iron grid over it is placed in the bin and the 

 whole over a fire. It is then worked in precisely 

 the same manner as the Stammers' barrel.

 first used in the Canadian Medical Service con-

 asbestos and an outer layer of corrugated iron
