closing days of the school year bring 



so many things to take the attention, 

 that the condition in which the working equipment of the laboratory is to be left 

 is likely not thought of, or receives only unsatisfactory care. One has but to 

 visit a few laboratories at this time of year to be convinced that the primary 

 reason why many teachers have to work with scanty equipment is that either 

 they or their predecessors have neglected to keep in perfect working order what 

 has been provided for them. To accumulate a satisfactory equipment, the pieces 

 as they are obtained must not be allowed to become worthless long before they 

 have served their possible period of usefulness. School boards should not rely 

 wholly on their teachers to care for the public property, for the care and preser- 

 vation of which they are even more responsible than the teachers. If they have 

 delegated those duties to the teacher, it is still for them to know that the work 

 has been properly done. 



The summer vacation affords, really, the only time when apparatus can be 

 spared from the laboratory for repairs. It is the best time to go over the equip- 

 ment carefully and make sure that every available piece is in the best possible 

 shape for the coming year's work, and in case repairs are needed, such may be 

 made with no inconvenience to teacher or pupils. Chemical apparatus should 

 be cleaned, and thus saved from the action of destructive chemicals. Physical 

 and optical instruments should be thoroughly cleaned, and protected from dust 

 and moisture. A few hours' work now may save an endless amount of trouble, 

 delay, and expense, when the apparatus is brought out for use at the beginning 

 of another school year.

Owing to a short leave of absence of the author, for the purpose of securing 

 much needed rest, the series of articles on Micro-chemical Analysis, by Prof. E. 

 M. Chamot, Cornell University, is not continued in this number, but will appear 

 again next month.
