The alx>ve list shows that a large amount of power is avail- 

 able from the Vaal River, but owing to the lon_^ lengths of pipe 

 line required to take advantage of the falls, it is impossible to say, 

 without careful estimates being prepared, whether the schemes 

 are financially sound or not. It is highly probable that hydro- 

 electric schemes at Engelbrecht's Drift. Parys, and Fourteen 

 Stream.'^ would be paying propositions ; but without making- 

 proper surveys and estimates of the cost, no definite conclusion 

 can be arrived at. The average flow of the river is given in the 

 first column, and the total power is roughly estimated at 466.616 

 theoretical horse power, while the actual, after allowing for 

 efficiency of plant, etc., will hv about 300.000 horse power.
