The second Central American Expedition 

 of the School of American Archeology reached 

 Guatemala on January 14 and steps were im- 

 mediately taken to continue the work inaug- 

 urated the preceding year. After a prelimi- 

 nary survey of the southern Maya field year 

 (January, 1910), it was decided that the 

 School of American Archeology would under- 

 take the excavation and repair of the ruins of 

 Quirigua in the Department of Izabal, some 

 fifty miles from the Atlantic coast. During 

 the first expedition the ruins were surveyed, 

 and a park laid out surrounding them. The 

 Great Plaza was cleared of underbrush and 

 the monuments were cleaned, photographed 

 and measured. A first hand study of the art 

 and inscriptions was undertaken and in both 

 eases the inadequacy of photographs and casts 

 for definitive conclusions was demonstrated. 

 The second expedition will continue the work 

 from this point. The luxuriant tropical 

 vegetation in which the ruins lie buried will 

 be felled and means taken to prevent the an- 

 nual reappearance of this destructive agent. 

 The laying bare of this site, the clearing of 

 the various pyramids, courts and temples will 

 doubtless be the main work of the present 

 season, though excavations will also be made 

 and the study of the art and inscriptions con- 

 tinued.
