176 THE JOHORE SURVEY. 



labour, by whicli also speed of progress would be attained. 

 On the other hand, it should be remembered that whatever 

 the speed of the staff, that speed must naturally depend 

 upon the speed of the jungle-cutters. 



From a consideration of the foregoing remarks one is 

 inclined to think that, in cases similar to that of the Johore 

 Survey, it would be advisable to send out some person 

 acquainted with either the country to be surveyed or ones 

 similar to it, to report upon the best general direction for a 

 line of traverse, and who upon instructions received would 

 undertake the cutting of the jungle- track, upon the comple- 

 tion of which an engineering staff could be sent out to 

 rapidly execute the work of traversing. In the case of 

 the Johore Survey, however, there were difficulties in the 

 way of adopting such a course. 



For cross-section work in the jangle, there is no doubt 

 that the theodolite is a better instrument than the level. 

 Large instruments should be avoided, 2|-inch and 4-inch 

 theodolites, or telemeters of Trough ton's pattern, or of the 

 Metford pattern, are best adapted for jungle work, especially 

 if fitted with double microscopes and micrometers in the 

 place of verniers. Englishmen have not as yet taken mucli 

 to them, bat Messrs. Troughton say that those who have 

 done so prefer them to verniers. Though a great deal more 

 might be said on this head, space does not permit of it. 



Before concluding, the author would like to place upon 

 record the fact that the kindness and hospitality of H.H. 

 the Sultan of Johore, as, indeed, of every member of the 

 Johore Government, whether native or English, will always 

 be pleasantly remembered by each and all of the Johore 

 Survey staff. 



The author wishes, in conclusion, to record his thanks to 

 his friend Mr. Douglas Scoones for the loan of his survey
