But perhaps even with the disquieting possibility of a foreign raid on our shores, denied by our politicians with such emphasis that we are led to believe in its existence, it is not necessary for us to base the plan of our towns on the arrangements of a camp. Such was the underlying plan of Timgad. It was divided, as was the conventional Roman camp, into four parts by two main intersecting streets. That which led from east to west was called _decumanus_, that which pointed north and south _cardo_. The former was a portion of the main road from Lambessa to Tebessa, and was doubtless the most used in the town. Its solid pavement shows the wear of wheels, as do the streets of Pompeii. It was naturally at the junction of these streets that the chief buildings were situate. Here is the Forum, with the Theatre behind it and the Municipal Library in front. Looking east from the Forum along the _decumanus_ we see the magnificent Triumphal Arch, the most impressive monument in the town. It is also the best preserved, and thanks to its existence the attention of scholars was called to Timgad in the first instance. With the aid of the excellent and well-illustrated handbook prepared by M. Albert Ballu, Architecte en chef des Monuments historiques de l’Algerie, the visitor will be able to identify and study the whole of the works excavated and restored. Probably most visitors to Timgad will have previously seen Pompeii, and will have some general acquaintance with the arrangements of a Roman town and the nature of its public buildings. Timgad will introduce them to some new features; of its Public Library and the romance of its discovery I shall speak later; it has a remarkably complete series of markets; and the public conveniences behind the Forum will interest those who are concerned about sanitary matters. However satiated with the wonders of the town itself the visitor should not omit to visit the Museum. Here amid the usual assemblage of mediocre Roman antiquities he will find some mosaic pavements of the highest excellence. Perhaps we are most of us disposed to be more interested in comparatively trivial matters of decoration and so forth than in the structure and disposal of important edifices. We are not all architects and town-planners. And here we may take especial delight in a little piece of evidence that even in this frontier city life was not all strenuous. On a stone of the Forum are graven the following words:— VENARI LAVARI LUDERE RIDERE OCCEST VIVERE
