Aircraft Services. 



i HE members of the British Guiana Coloniza- 

 tion Deputation now in London have 

 made a visit to the Handley Page 

 aeroplane works, where they will have had an oppor- 

 tunity of discussing with experts t-he possibilities of 

 emplijying aviation for the development of the 

 extensive colony they lepresent. 



In the last issue ot this Journal we called attention 

 to the growing importance of the aeroplane for 

 mapping and survey purposes. During the war our 

 airmen succeeded in mapping by photography almost) 

 the whole of eastern France. If this can be done under 

 the difficulties and dangers of modern warfare, one 

 would suppose that it would be a comparatively simple 

 though not necessarily inexpensive matter in times of 

 peace. 



The possibilities of aircraft for survey work 

 would be great. Forest land, savannahs, the course 

 of rivers and streams, the position of hills and 

 mountains, could be quickly and accurately delineated. 

 It would be possible for agricultural experts on soil 

 and vegetation, for geologists and surveyors, to travel 

 in machines engaged in this work. They could 

 supplement the maps of the observers with notes 

 of a technical character. In this way the development 

 possibilities of the interior of a country like British 

 Guiana could be <]uickly studied and the lesults 

 usefully co-ordinated. 



It is interesting to note that in the United 

 States, the aeroplane is being used for the detec- 

 tion of forest fires. Army machines and captive 

 baloons cover portions of the national forests 

 of California, Arizona, and New Mexico. These ma- 

 chines co-operate with the Forest Service principally 

 in the matter of reporting the position of outbreaks 

 by wireless. But experiments are in hand to test 

 the possibility of extinguishing the.se fires by bomb- 

 ing. The bombs, it is presumed, will contain some 

 substance like liquid carbon dioxide which will have 

 the same etFecD on fire as the contents of the common 

 house-fire extinguisher.
