As to the motive power to be supplied to our 
proposed railways of the interior, I tliink the advantaj^es 
of electricity are self-evident, with means of generating 
it l)y water power so ready to hand in the several 
districts, as compared with the long distance from a 
cheap coal supply. 
Not alone does the c^reat Kaieteur Fall on the 
Potaro River offer itself as a vast source of supply in 
this direction, but also the smaller falls and rapids in 
the other rivers crossed en route, all of which could be 
made available as sources of generating power. 
In the absence of a detailed survey of the interior 
of the country, it is impossible to attempt anything 
approaching an accurate estimate of the probable cost 
of the railways projected ; but as a more or less 
speculative approximation, I may venture to name a 
million and a half sterling for the Essequebo and 
Mazaruni trunk lines, and another half million for the 
Cuyuni : an expenditure which I feel sure is entirely 
beyond the capacity of the colony to undertake on its 
own account : the only possible way of accomplishing 
the opening up of the interior is by means of liberal 
concessions in land and mining rights, offered to out- 
side capitalists. 
In submii'oing this paper, my object h*is been to 
ventilate the subject and thereby arouse some interest 
and discussion on the possibilities of our colony's future. 
The paper was accompanied l)y a chart of the central 
river districts of the colony, showing the projected 
railway lines as described, a reduced reproduction of 
which is hereto appended.
