The goat is very much in evidence in Malta, and supplies practically all the milk used. There is, it is said, one goat to every ten of the population, so that, as there are 200,000 inhabitants, there must be about 20,000 goats. Flocks of them wander about the streets from morning till night, and are milked as required at the customers’ doors (Fig. 6).
