;are within the international zone, and consequently 

 they could .only .be. 'exploited by arrangement with Spain. No 

 agreement having been reached, the river has not been 

 harnessed, and the energy to be derived from its waters is 

 being wasted. The permanent power of the Douro alone is 

 estimated at 102,000 horse-power, and that of the whole hydro- 

 graphical basin is calculated at 309,000 horse-power. 



According to studies made, the tributaries of the Douro 

 would yield the following permanent energy: 



Coa 41,000 h.p. 



Sabor 6,000 h.p. 



Tamega and Tua 12,000 h.p. 



Paiva 12,000 h.p. 



Totalling 71,000 h.p. 



which are outside the zone fixed by the Spanish Convention. 

 The Kiver Lima, at Lindoso, yields 3,500 h.p. It is the only 

 big dam already carried out in Portugal with Portuguese and 

 Spanish capital. The Kiver Cavado is reported to yield 38,000 h.p. 

 (permanent power). 



The Vouga basin is supposed to yield 12,000 h.p., according 

 to the studies made. 



The Eiver Mondego is estimated to yield 20,000 h.p. The 

 Tagus yields 40,000 h.p., and its tributary, the Zezere, yields 

 more than 20,000 h.p., according to the studies made. 



The energy of the River Guadiana is estimated at 30,000 h.p. 



The distribution of the water-power in Portugal is thus 

 centred in the north of the country. 



The total permanent power available is estimated at 500,000 

 h.p. and the temporary power (during the rainy season) at 

 400,000 h.p. 



The hydro- electric installations actually working number 

 18, totalling 16,900 h.p. 



The number of schemes submitted to the competent depart- 

 ment exceeds 200, but, except for schemes, hitherto very little 

 capital has been invested in harnessing the rivers of Portugal. 

 No investment on a large scale could be more remunerative for 

 foreign capital. The cost of the works is estimated at 1,000-2,500 

 escudos per horse-power installed. Two-thirds of the works are 

 paid in Portuguese currency. Therefore, calculated in sterling, 

 most of the works would be cheap. But that is only one side 

 of the problem. The progress resulting for industries and 

 agriculture would immediately increase the purchasing power of 

 the country, and the reduction in the importation of coal, with 

 freight and insurance added to the high prices ruling, would
