WE ARE PREPARED TO UNDERTAKE 

 AERIAL PATROLS AND SURVEYS AT RATES 

 VERY MUCH LOWER THAN HITHERTO 

 DEEMED POSSIBLE. 



Our Aerial Photo Topography 

 work determines elevations and 

 contours accurately. Our photo- 



graphs determine different varie- 

 ties and numbers of trees. 



Our experience is unequalled. 

 The Air Express Services of the 

 Aircraft Transport «& Travel 

 Company between London, Paris 

 and Italy, and between London 

 and Holland have operated with 

 greater punctuality than the 



trains connecting with the Chan- 

 nel steamers. Our allied enter- 

 prises cover the world. We are 

 the only firm in existence that 

 has successfully carried out com- 

 mercial air services and aerial 

 surveys. 



Our association with 

 THE GREATEST AIRCRAFT ENTERPRISE 

 IN THE WORLD 

 the superiority of our technical equipment and 

 GUARANTEES SUCCESS.
