The gold value of the currency peso (75 = £1 in 1903, 70 = £I in 1904, 58 = £1 in 1905) fluctuates between limits so wide that conversion into sterling (especially for a series of years), with any pretension to accuracy, is impracticable.
The total value of the foreign trade fluctuates very greatly, and the difficulty of forming an estimate is enhanced in many years by the absence of official statistics; but imports and exports together probably amount in a normal year to about £I,000,000.
Production.-The total wine production of the world, which, 'of course, fluctuates considerably from year to year, amounts to roughly 3000 million gallons.
