Again, it has been shown that the teachers find the Lecture 

 Sets with manuscripts great time savers and therefore even 

 more useful than the general slide collections. About 43% of 

 the slides loaned during the year were in these sets. This 

 percentage would have been higher had more duplicate sets 

 been available. As it was, the Department was unable to fill 

 all the requests for several of the sets. Several new sub- 

 jects have been added recently to the series, namely: 



Set No. 27 — Russia in Europe — Its Physical Features, by 

 Alia Kretchman 



Set No. 28 — Our National Parks, by Grace E. Fisher 



Set No. 29 — Visiting the Other Americans, by Grace E. 

 Fisher 



Set No. 30 — Plymouth and the Pilgrims, by Jannette Lucas 



There are thirty prepared lectures, and, as several of these 

 have been duplicated, the total number of sets in circulation 

 is forty-five. 



A new edition of the general catalogue of lantern slides was 

 issued in October, 1920. This catalogue gives the different 

 topics in geography, history, natural science, and industries, 

 and the number of slides available under each group. 



The lending of slides is the one phase of the Museum's 

 educational work which receives any direct financial support 

 from the Board of Education. In 1920, $2,000 

 Support from was appropriated for this work. This is the same 

 Education amount allowed as in 191 6, although the circu- 

 lation of slides has increased 260%. This appro- 

 priation is wholly inadequate, but rather than see the work 

 stop, the Trustees met the deficit for 1920.
