meets the requirements of the Timber Branch. The mechanical features and 

 mounting arrangement have been passed by the Department of Transport. 

 Seeding on an experimental basis will be carried out early in May. 



Portable Steam Cooker 



The purpose of this project was to design and produce a portable steam 

 cooker, the aim being to improve the standard of meals at forest fire and other 

 bush camps. 



The main advantages of this method of cooking are: 



1. Less cooking skill required 



2. Food practically burn-proof 



3. Meals can be kept hot on a 24-hour basis 



4. Sanitary — due to stainless steel construction 



5. Plentiful supply of clean hot water constantly vailable for cooking 

 and dishwashing 



6. Minimum food wastage 



For versatility of food preparation, aluminum grills have been provided. They 

 can be used for frying meat and eggs. An oven may be added later. 



The cooker was tested at the Ranger School and received favourable com- 

 ment. The estimated capacity is 60 - 65 men. The source of heat can be fuel 

 oil, propane gas or wood. 



A half-size model is presently under construction. This is considered a more 

 practical size. Similar units can be added as the camp grows in numbers.
