A Higher Elementary School should, in general, be planned in accordance with the principles already described, as applied to ordinary public schools. Such a school for 300 to 350 scholars would usually require 8 to 10 classrooms, since every class should have its own room, no room accommodating more than 40. Rooms may be furnished by single or dual desks as desired. If single, a room should have area of about 15 square feet per scholar. If with dual desks, allow a minimum of about 12 square feet per scholar. If Cookery, Laundry, or Handicraft be taught, a room should be provided in accordance with the rules previously given for same.
If Advanced Drawing is taught, a separate room is desirable, and should provide 30 square feet of floor space for each person using it at any one time. If the school has a suitably lighted central hall, it would answer this purpose, but no other than a drawing class should be held in a central hall.
A Laboratory (if included) should afford the same floor space as above, must have suitable tables, well lighted, and fitted as required for experimental work. If it be used for Chemistry it should have sinks, cupboards, and the necessary fume closet.
Should there be a separate lecture-room where Chemistry also is taught it should be fitted as above ; or one or more classrooms may be fitted as above instead of providing a separate lecture-room. A small preparation-room may be provided near a lecture or other room used for this purpose in schools where Science is taught.
