Transportation.— The increase of the scope of the 

 Museum's work necessitates extended explorations. These 

 explorations are too often limited in their results, especially 

 in distant fields, because of the difficulties of transporting the 

 material secured. The generous aid, however, of various 

 railways in granting passes to our curators and assistants to 

 and from their distant fields of explorations and in carrying 

 the collections at reduced rates has made possible field opera- 

 tions which otherwise would not have been undertaken, and 

 I wish to acknowledge our indebtedness to these companies. 

 The following have extended many courtesies to us during 

 the past year:
