identified. In connection with this investigation, a special study 

 has been made of the different types of construction employed in the 

 dated monuments of the Hadrianic period. 



The more important of the individual monuments inside the city, 

 to which especial attention has been given during the year, are the 

 domus Tiberiana on the Palatine, the so-called Temple of Augustus, 

 and the porticus of Gains and Lucius in the Forum, concerning the 

 last of which a discussion appeared in the March number of the 

 American Journal of Archaeology. Owing to the more urgent claims 

 of the work near at hand, it has not been possible to continue the 

 systematic study of the important monuments brought to light by 

 the recent excavations at Ostia, which was begun during the last 

 year. Considerable time has been devoted, however, to an examina- 

 tion of the remains at Porto of the port of Ostia, built by Trajan, as 

 an aid in determining the date of a number of the more important 

 monuments in Ostia itself. 



The months of March and April were spent in a general examina- 

 tion of the extensive Roman remains in North Africa. The most 

 important points visited in Tunis were Carthage, Susa, El Djem, 

 Sbeitla, Thelepte, Dougga, Bulla Regia, and Smitthu, while in 

 Algiers, though the greater part of the time was devoted to Lambese 

 and Timgad, brief visits were made also to Tebessa, Guelma, Con- 

 stantine, Biskra, Algiers, Guyotville, Cherchel, and Tipasa. The 

 remains seen, though often impressive on account of their vast extent 

 and size, are conspicuous for their lack in structural finish. It is 

 clear from their technique that in the erection, even of the great 

 monuments, native workmen and methods were almost wholly 

 employed. From the prevalence of concrete construction, as well as 

 from its appearance in many early monuments, it seems possible that 

 the knowledge of its use antedated the Roman domination. Many 

 valuable data for the study of the early Roman construction were 

 gathered from an examination of the buildings made of sun-dried 

 brick in southern Algiers.
