Before he sets forth on more ambitious journeys, the master, temporary or permanent, of a motor-car may make several interesting expeditions in the neighbourhood of Algiers. The guide-book will suggest his objective, the excellent maps of the “Voies de Communication” will point out the way. If his tastes run in the direction of visiting historic sites, he may spend a very interesting day in motoring to Cherchel, the ancient Julia Cæsarea, situate on the coast about seventy miles west of Algiers. He has a choice of routes; he may proceed inland to Blidah, and thence to Marengo, and so to Cherchel, and return by the coast road, or vice versa. We chose a middle course. We followed the Blidah road as far as Boufarik and then turned westwards by country roads to Marengo. With occasional interludes of roughness, especially where the marshy nature of the country renders their maintenance difficult, these roads are very good. They traverse a well-cultivated district of the great plain between the coast-hills and the Lesser Atlas, of which the snowy summits are brilliant in the morning sun. On a hill to our right we catch a glimpse of the curious Tombeau de la Chrétienne, so called;—in all probability the mausoleum of Juba II and Selene his wife, the founders of Cæsarea. It is placed on the summit of a hill 756 feet above the sea, and is a circular building of about 130 feet in height. Like most Roman buildings it has been used as a quarry by subsequent peoples; perhaps the solitary capital of a column which I noticed on a farm gateway came from this source.
