However, a com- parison of the average prices of olive oil at Marseille with the volume of the annual exports from Sfax furnishes no evidence that the price is the chief factor in determining the quantity exported each year. It is also uncertain to what extent the coming into bearing of the recently planter] orchards may affect the figures, although presumably the addition thus made to the total production lias been a gradual one and not likely to cause marked fluctuations. In the main, therefore, it is believed that the above figures are fairly representative of the annual crop. To arrive at the total annual production of oil by the Sfax orchards we must add to the figures in the column showing quantity pro- duced. 531,700 gallons, representing the average amount that is consumed locally or shipped overland to other parts of northern Africa. This is said to vary little from year to year.' Although the records do not cover a sufficiently long period to establish a definite relation, it would appear that there is some con- nection between the size of the cro
