Generally speaking, there is a daily or even bi-daily motor service on all the main roads of North Africa; and it is only in the far south that the bus does not have a regular time-table. Otherwise the times of departure and arrival are as fixed as for a train. The motor-busses are covered and very comfortable, and to the individual who is entertained by strange faces and gay chatter about all that is going on in the country through which he is traveling, the motor _diligence_ is a delightful entertainment. In fact, if the traveler is bent on studying the country and its people, he will do so much more advantageously in the public conveyance than in the isolation of the private car. However, if he is only on holiday or a pleasure trip the motor is recommended, and it is with the idea of traveling thus that this imaginary journey will be taken. It is presumed that the period chosen for the tour will be between December and April—January, February or March—and let it be borne well in mind that North Africa in winter, even on the edge of the Sahara, is not a warm country. The thermometer does not actually drop very low, but the biting air of the mountains and the sharp dry winds of the rolling plain or the Hauts Plateaux and the Sahara make heavy coats and rugs essential. Once south of Laghouat and at Touggourt the temperature is definitely warmer than in the north, but hot days can not be depended on before this latitude is reached. It is true that on the edge of the Sahara the sun heat in the middle of the day makes it impossible to go out bareheaded, but the nights are very sharp. Once into the Sahara the nights are also cold, but in the day it is pleasantly warm, and the overcoats and rugs can be put away; but the return journey across the Kabyle Mountains may be done in a snowstorm. The great thing to remember about Algeria is that it is a country of extremes. The morning may dawn in a downpour of rain and at noon one may lunch in the garden dressed in white. Crossing the mountains during the winter one is practically certain to find rain, but once on the Sersou it is almost always fine. The Hauts Plateaux are bitterly cold, but as soon as one has come down on to the Sahara the temperature is very pleasant, and it rarely rains; when it does, it pours for a few hours and then clears up. Therefore, the warmest wraps for the journey in the north, English summer clothes (not Indian or tropical) for the south. All evening dresses, etc., can be left in Algiers, as there is never any occasion to dress up, even when invited by an Arab chief. It is advised to travel light, and linen can usually be washed by the Transatlantic hotels in forty-eight hours. The question of hotels brings me to another point.
