We were travelling south at the very season when the natives were migrating north. I saw plainly that it would be impossible for us to continue our journey during the wet season, as the camels had the greatest difficulty in carrying their loads even now, at the commencement: their feet sank deep into the soil; this formed adhesive clods upon their spongy toes, that almost disabled them.
The farther we travelled south, the more violent would the rains become, and a long tropical experience warned me that the rainy season was the signal for fevers. All the camels of the Arabs were being driven from the country; we had already met many herds travelling northward, but this day's march was through crowds of these animals, principally females with their young, many thousands of which were on the road. Some of the young foals were so small that they could not endure the march; these were slung in nets upon the backs of camels, while the mother followed behind. We revelled in milk, as we had not been able to procure it since we left Cassala. Some persons dislike the milk of the camel; I think it is excellent to drink pure, but it does not answer in general use for mixing with coffee, with which it immediately curdles; it is extremely rich, and is considered by the Arabs to be more nourishing than that of the cow. To persons of delicate health I should invariably recommend boiled milk in preference to plain; and should the digestion be so extremely weak that liquid milk disagrees with the stomach, they should allow it to become thick, similar to curds and whey: this should be then beaten together, with the admixture of a little salt and cayenne pepper; it then assumes the thickness of cream, and is very palatable. The Arabs generally prepare it in this manner; it is not only considered to be more wholesome, but in its thickened state it is easier to carry upon a journey. With an apology to European medical men, I would suggest that they should try the Arab system whenever they prescribe a milk diet for a delicate patient. The first operation of curdling, which is a severe trial to a weak stomach, is performed in hot climates by the atmosphere, as in temperate climates by the admixture of rennet, &c.; thus the most difficult work of the stomach is effected by a foreign agency, and it is spared the first act of its performance. I have witnessed almost marvellous results from a milk diet given as now advised.
Milk, if drunk warm from the animal in hot climates will affect many persons in the same manner as a powerful dose of senna and salts. Our party appeared to be proof against such an accident, as they drank enough to have stocked a moderate-sized dairy. This was most good-naturedly supplied gratis by the Arabs.
