REPORT OF NATIONAL MUSEUM, 1922. 99 



Australia, Brazil, Colombia, Dominican Republic, Ecuador, Japan, 

 Mexico, Peru, and Venezuela. 



Through the continued cooperation of the States Relations Service 

 of the Department of Agriculture, prize-winning jars of fruits, vege- 

 tables, and meats, put up by members of boys' and girls' canning 

 clubs and selected by State demonstration leaders, have been received 

 for exhibition in the section of foods, and eight colored bromide 

 enlargements of photographs showing a girl club member canning 

 by the cold-pack method were obtained from the office having charge 

 of the boys' and girls' club work. 



The American Relief Administration, which has had charge of the 

 feeding of destitute children in Europe, after the special exhibition 

 of its work here in the Museum during January, 1922, presented 

 numerous photographs, charts, and printed documents illustrating 

 the feeding of Austrian children, the methods used in determining 

 those which were undernourished, and the computation and meas- 

 urements of standards of diet. This material will be of value for 

 comparison with our present exhibit arranged to show the fuel value 

 in calories of ordinary articles of food. 



WORK OF PRESERVING AND INSTALLING COLLECTIONS. 



All of the collections under the care of the curator have been care- 

 fully inspected for insects, and all perishable material like wools 

 and foodstuffs have been fumigated several times, and the board 

 specimens of fresh lumber were treated with kerosene to prevent at- 

 tack by termites. This has meant, however, constant vigilance. 



The cataloguing of new specimens has been kept up to date, and 

 the installation of new material has been made as soon after its 

 receipt as was possible. A large part of the time of one preparator 

 was given to making gummed letter case labels for the textile ex- 

 hibits and for the medicinal collections. 



The examination and indexing of new textile terms and other 

 special information contained in the large number of trade papers 

 and periodicals received by the sectional libraries of textiles, woods, 

 medicine, and foods has occupied the time of the preparators when 

 not engaged in other duties. 



Four new permanent installations and a special temporary exhibit 

 were set up in the division of textiles during the year. A special 

 exhibit of live silkworms was installed in the south hall during the 

 second week in June, 1922. For this purpose about 500 silkworms 

 of different ages representing the Italian and Japanese varieties 

 were presented by Mr. T. J. Keleher, of Washington, D. C. The 

 more mature of the silkworms finished feeding and spun their cocoons 

 to the delight of hundreds of school children. The younger insects, 

 however, were lost, owing to a poisoning of their food suppty by the
