During the months of September and October 19 10 regular work was 

 continued on the general classification, on the basis of materials and methods 

 of construction, of the more important ancient monuments inside the city of 

 Rome. The month of November was mainly devoted to the determination 

 of the various periods of construction to be found in the Colosseum. This 

 preliminary study revealed the presence of at least four distinct types of 

 construction, belonging to as many periods, making clear also the original 

 unity in structure of the three lower stories and the probable later construc- 

 tion, in wood, of the fourth story; also the extent of the fire in 217 A. D. 

 and the restoration resulting from it, as well as the character and extent of 

 the later restorations. In connection with this investigation, many remains 

 in the vicinity were identified as of the Flavian period, the most important 

 of which are the arches of the aqueduct between the Cselian and the Palatine 

 hills, usually assigned to the period of Septimus Severus. 



In the Forum the history of a number of the monuments, as shown by 

 their construction, has been wholly or in great part completed. Among these 

 are the two Basilicas, the Regia, the temple of Castor, and the so-called 

 temple of Augustus. The most interesting results, however, have been the 

 discovery of the extensive remains still left, though unrecognized, of the 

 Forum of the period of Augustus, and the location of several monuments, 

 hitherto unlocated ; the most important of these is the Porticus of Lucius 

 and Gaius, built by Augustus. 



The recent publication of a new plan of the center of the ancient city, 

 made by the School of Engineers of Rome, has rendered easy the resumption 

 of the study of the levels on the Palatine and in certain other parts of the 

 city. The work on the Palatine so far has led to the assignment of the 

 greater part of the existing remains, except those on the southwest corner of 

 the hill, to the period of Domitian. 



The months from December 1910 to April 191 1, inclusive, were spent in 

 America. During that time conferences were held with a number of the 

 leading authorities on modern brick-making and concrete construction, as 

 well as with many workers along allied lines. Two papers on the methods 

 of investigation used in the work in Rome were presented at the annual 

 meeting of the Archaeological Institute of America, at Providence, Rhode 

 Island. Sixteen formal and a number of informal lectures were delivered 

 in various universities and colleges. Among these institutions were the 

 universities of Chicago, Johns Hopkins, Michigan, Oberlin, Ohio, and Penn- 

 sylvania, and the colleges of Holyoke, Smith, Swarthmore, and Wells. 



The remaining months of the year have been spent for the most part in 

 the regular work in Rome and the immediate vicinity.
