Tan.. 1922. Annual Report of the Director. 39 



the department was fortunate in securing the services of a former as- 

 sistant, his work was not of a wholly productive nature owing to 

 the many demands made upon his time by the repairs that were 

 necessary to entomological specimens and to group accessories. Sev- 

 eral conferences were held with Mr. Dudley Grant Hays, Director 

 of Visual Instruction in the public schools, for the purpose of dis- 

 cussing the system of loaning cases to the schools and of the study of 

 them while there. On Mr. Hays' recommendation, a list of case sub- 

 jects available for school use was placed on file in the office of each 

 principal where it could be consulted by the teachers with a view to 

 making- selections which would correlate certain lessons. He also sent 

 to all public schools and branches a bulletin containing directions for 

 reaching the Museum, rules of admission to it, references to lunches 

 and lunch room, and requests to teachers as to the care of loan 

 cases. In many other helpful ways, Mr. Hays has taken active pan. 

 The new chassis purchased during the school vacation and fitted to 

 the old. but repaired and repainted deliver}- truck body, is better 

 suited for the purposes of this department than the former one. 

 With it. it has been possible to maintain a school day schedule since 

 the beginning of its service. This schedule consists of collections 

 of cases from ten schools and the delivery of them to the same number 

 of schools. With the former chassis only eight collections and de- 

 liveries could be made. The addition of thirty-two more schools to 

 the previous schedule demanded this increased daily service. With 

 this addition a total number of 320 schools is listed to receive the 

 cases. Additional visits of inspection and inquiry were made by 

 members of the bureau of exhibits of the United States Depart- 

 ment of Agriculture. Desirous of having in Pittsburgh a circu- 

 lating system of loan cases similar to the Harris Extension, Mr. 

 John A. Hollinger. Director of Visual Instruction in the public 

 schools of that city visited the Chicago public schools for the pur- 

 pose of getting first hand information as to the utilization of the 

 cases of this department and the benefit derived from them. He 

 also sought information of this department concerning its meth- 

 ods of preparing and circulating its cases. Upon request twenty- 

 five cases were loaned at one time to the Washburne Continuation 

 School for its course during July and August. The three classes 

 of students in this school are: the disabled soldiers assigned to it 

 by the Federal Board of Vocational Education; apprentices in dif- 

 ferent trades; and the fourteen to sixteen year old working boys who 

 are required to attend school eight hours a week. In connection with 

 the loan of the cases to this school, Mr. E. G. Bauman. in charge
