and shelter-cave chamber; models of bridges, pontoon boats, and 

 wagons, and a caniouflaged-gun position. 



Other contributions, through the Quartermaster Corps, added uni- 

 forms and insignia fully representing the uniform and individual 

 personal equipment worn by officers and enlisted men of the fol- 

 lowing countries and the colonial possessions of each: Belgium, 

 France, Great Britain, Italy, Japan, Austria, Germany, and Tur- 

 key. This series forms a marvelously complete collection and will 

 be a priceless source of information for historical purposes. 



The Medical Department completed the extensive series begun last 

 year of objects illustrating the work of that branch of the United 

 States Army, and it was duly installed this year under the supervision 

 of Mr. F. L. Lewton. The field equipment included first-aid kit 

 and emergency belt worn, by all enlisted men in the Medical Corps, 

 field operating table, instruments, dressings, and other supplies, 

 complete portable and the emergency dental outfit for carrying 

 in hand, field kitchen, disinfector, sterilizing outfits, litters, am- 

 bulances, etc. The base hospital material for exhibition, was grouped

 bronze and silver commemorative medals issued by Belgium, France,
