D. Seeds for School and Home Planting. — In order to assist 

 the above work, penny packets of seeds are put up by the Botanic 

 Garden for children's use. In the early spring", lists of these 

 seeds, conditions for entry as an exhibitor, and other information 

 may be secured on application to the Curator of Elemeiitary In- 

 stritction. 



E. Conferences. — Conferences may be arranged by teachers and 

 principals for the discussion of problems in connection with gar- 

 dening and nature study. The last Monday afternoon of each 

 month will be reserved for such conferences : appointments must 

 be made in advance. Address Miss Ellen Eddy Shaw. 



F. Study and Loan Material. — To the extent of its facilities, 

 the Garden will provide, on request, various algae and protozoa, as 

 well as living plants, leaves and twigs, or other plant parts for 

 study. Where containers are necessary, as in the case of the algae 

 and protozoa, they must be furnished by the school. Petri dishes 

 will, on request, be filled with sterilized nutrient agar ready for 

 use in the study of bacteria and molds. They should be delivered 

 to the Garden, clean, and in general one week before the agar is 

 desired. In all cases arrangements must be made by the teachers 

 for calling for such material.
