maintained at all times, with the exception of one series of three minor inter- 

 ruptions of several hours' duration each, shortly after communication was 

 opened. In this connection, it may be worthy of note that these sets which 

 were designed to operate over a distance of not more than seventy-five miles 

 have consistently operated over the 600 miles separating Sioux Lookout from 

 Timagami. 



Records show that total traffic for the season has increased by 4G1 per cent, 

 or from 58,239 words in 1927 to 233,855 in 1928. Tables attached show traffic 

 of the Hudson District up to the close of the present fiscal year. 



In order to develop this service properly, it will be necessary to provide 

 permanent space for storage, testing and construction. This space should be 

 in Toronto. 



4. Miscellaneous Investigations. 



In addition to the above-mentioned operations, two minor projects have 

 been carried on during the past season. Of these, the more fully developed is 

 the project to provide a photographic horizon map for lookout towers. Maps 

 of this type which would serve as a connecting link between a standard tower 

 table map and the actual appearance of the landscape as seen from the tower, 

 are of importance since the number and use of towers is rapidly increasing. 

 Investigation of the possibilities of this work have now gone far enough to 

 warrant the conclusion that a satisfactory solution is possible. Details of 

 apparatus and procedure are, however, still unsettled and since much of the 

 work depends on suitable photographic weather, their completion is uncertain. 

 Field work for the past season was carried out in co-operation with the North 

 Bay office from the Timagami lookout tower. The second project of potential 

 importance was undertaken for the Sudbury office, to determine the possibility 

 of mapping different classes of ground cover on the basis of relative inflammability. 

 In particular, it; was desired to determine the possibility and the extent to which 

 this work could be carried out, by aerial survey methods. Two townships were 

 partially completed, but, owing to the unfavourable season and shortage of 

 survey flying, no conclusive tests could be made.
