The model represents one of a fleet of steamers of the same type belonging 

 to the " Irrawaddy Flotilla Company," which are used for the general traffic 

 of the river Irrawaddy from Eangoon, in British Burmah, to Bhamo, in 

 Upper Burmah, near the frontier of China, the whole distance by river being 

 nearly 1,000 miles. 



Each steamer carries light goods and passengers, arid takes in tow two iron 

 barges each 190 feet long 'and carrying from 300 to 500 tons weight of general 

 cargo according to the season. In the dry season the river is very shallow 

 in many parts, and in the wet season the current is very strong ; the vessels 

 have therefore to be all of very light draft and great power.
