showing detailed locations of tentative boundaries which 

 formed the basis of discussion in the Supreme Council. Less 

 pretentious but very effective was the equipment for repro- 

 ducing by photostat and other processes the large quantity of 

 special maps demanded by the American delegation. In like 

 manner other delegations had the cartographic equipment best 

 adapted to their special needs. Any style of map needed at 

 the conference could be produced on short notice, if not by 

 one delegation, then by another. In order that the American 

 delegation might have at its disposal the latest geographical 

 material produced in neutral and enemy countries, Major Law- 

 rence Martin was sent on a special mission to various parts of 

 central Europe, and through his efforts new maps were con- 

 stantly being added to the collections in the Hotel Crillon. 



The importance of relief models in military operations has 

 already been emphasized. Believing that such models would 

 prove of inestimable value in the peace negotiations, the pres- 

 ent writer submitted, before the close of the war, a project for 

 the manufacture of large-scale relief models of every territory 

 likely to be in dispute at the Conference. Details of the plan 

 were worked out in collaboration with the French geographer, 

 De Martonne, and submitted to General Bourgeois of the Serv- 

 ice Geographique, who gave his hearty approval and support. 

 The French Government adopted the project, and work began 

 at once with American and Italian cooperation. Before the 

 tremendous task could be completed hostilities ceased, but the 

 work continued during the sessions of the Conference. Full 

 series were in time available for the west bank of the Rhine, 

 the Saar Basin, the Belgian frontier, the northern Italian 

 frontier region, the Julian Alps and Istria, and the east Adriatic 

 coast ; and large areas of Albania, Bohemia, and certain other 

 districts were completed in time to be of real service. In the 

 large rooms set apart for maps and models at the Hotel Cril- 

 lon the American Commissioners studied frontier questions on 

 facsimile reproductions of the real topography of disputed ter- 

 ritories. Groups of the models were occasionally transferred
