106 REPORT OP NATIONAL MUSEUM, 1924 



is limited only by production facilities and the supply of raw ma- 

 terial, which latter seems to be endless. 



The Brunswick-Balke-Collender Co., of Chicago, 111., continued 

 their cooperation by presenting to the Museum a miniature billiard 

 table, sample cues, wood triangle, set of pocket balls, and a bowling- 

 alley section. The billiard table is a most artistic one. It is made 

 exactly to scale with a regulation table and of the same materials. 

 The wood used is African mahogany and has been given the hand- 

 some English brown finish. The table is inlaid with ebony, white 

 holly, and mother-of-pearl. The bowling alley section is of edge- 

 grain hard maple in strips carefully glued and clamped together 

 and highly polished in natural finish. 



Drake Process (Inc.), Cleveland, Ohio, has developed a unique 

 industry which blows wood pulp into molds, and forms, in one opera- 

 tion, hollow containers and other articles of almost every conceivable 

 size and shape. This company enhanced its former exhibit by con- 

 tributing 36 more specimens of its products, including a radio rotor, 

 hardened by special treatment; quart berry boxes with bottoms 

 perforated for ventilation; soaj)-powder containers; and a triangle 

 salt can. 



Continuing their cooperation with the Museum, the Paine Lum- 

 ber Co., Oshkosh, Wis., presented two fine veneered doors of their 

 latest design. One is a brown ash, two-panel door, finished light 

 golden on one side and dark on the other. The second, a one-panel 

 Miracle door, is of red birch, finished on one side as dark mahogany, 

 and on the other similar to English oak. 



WORK OF PRESERVING AND INSTALLING COLLECTIONS 



The assignment of the southeast court gallery for hygiene and 

 sanitation exhibits has made it possible to utilize a few of the 

 cases of this gallery for the exhibition of medical collections. Ad- 

 vantage was taken of the delay in the receipt of the permanent 

 exhibits for this gallery to relieve the congestion in the division of 

 medicine. Eventually this entire gallery will be devoted to the 

 subjects of hygiene and sanitation. Sixty-two new or rearranged 

 installations were made during the course of the year. Fifty-two 

 cases were utilized for new material and ten used for transferred 

 or rearranged exhibits. Sixteen child-welfare posters were framed 

 and hung on the pilasters over the hygiene and sanitation exhibits. 



Thirty-three new permanent installations of exhibits assigned 

 to the section of organic chemistry were made during the year, also 

 four installations of textile products in the south hall. These in- 

 cluded various rubber industries, the manufacture of cements and 

 glues, plastic resins, hot- and cold-molded products, furs, brushes.
