Construction & Maintenance op Roads, &c. 29 



yiz: at " Queenstown," Maria's Lodge, "Adventure," 

 and " Hibernia," and in Berbice one has been erefted 

 at " Belladrum" and another at " Whim." One re- 

 mains still in hand and is intended for the Gibraltar side- 

 line, to complete the drainage scheme of the Fyrish block, 

 as it is called. These bridges cost landed here ;^49.io.o, 

 or $237.60 each, and the ereftion $680, including trans- 

 portation from Georgetown to the spot on which 

 it is placed. The cost of a wooden bridge of the old 

 style is from $300 to $350 and in some parts of 

 the colony $500 or more, and the cost of the iron 

 on concrete basements are, on an average, $950. 

 The latter will last a life time, with no other expense than 

 a coat of paint occasionally, the former requires re- 

 newing every 4 or 5 years, with repairs at intervals. 

 The iron bridges in Essequibo are I have no doubt well- 

 known to the president of this Society, and I am inclined 

 to believe, that if questioned, he will admit that they 

 have been erefled in a workmanlike manner, have every 

 appearance of lasting for many years to come, and are a 

 credit to the colony. I beg to lay over with this paper a 

 rough sketch of our iron bridges on concrete walls as 

 crc6lcd by the Commissary's Department.
