and it is worth while to note that they use no hot 

 water tanks in their hatching rooms. Hot air 

 suits them better because it is easier to control 

 than hot water, and more economical important 

 items in a hot country and where fuel is high. 



Though slow to adopt improvements, it is proba- 

 ble that they will ultimately make use of the porta- 

 ble incubators which require no night attendant, 

 and with which each farmer may do his own hatch- 

 ing at home. More than ten years ago a French 

 company in Egypt were using portable incubators 

 in hatching ostriches at their ostrich park at 

 Matareeyeh, which lies ten kilometres northwest of 

 Cairo and one kilometre south of the ruins of Helio- 

 polis, not very far from the old railroad which runs 

 direct from Cairo to Suez.
