A good preserving' 

 liquid may be made as 

 follows : 50 parts meth- 

 ylated alcohol, 50 parts 

 water, 4 parts formalin. 

 This mixture can be 

 prepared by any drug- 

 ofist at a cost of about 

 25 cents per pint. It 

 must be kept closely 

 corked as it evaporates 

 very readily. Special 

 bottles with bent necks 

 are very suitable but 

 rather expensive, costing 

 about 5 cents each. Two 

 drachm horacEopathic 

 vials^with wide mouths 

 may be obtained from 



Fig. 17. Vials for preserving larvic in liquid. drUggists at lUUCh lower 



rates and will answer very well. 



Historical Collections. 



Objects that link the past to the present are of great educational 

 interest and value. Such things are found in every neighborhood, and 

 the school is the proper place for their keeping' and interpretation. 

 The boy who has picked up an ancient arrowhead or pipe from the site 

 of some long-forgotten village may well feel a personal interest in the 

 early exploits of Huron and Iroquois. But we need not go back to 

 Indian times for relics of the past. The early pioneers of our own race 

 have disappeared, too, and their primitive weapons, tools, and manu- 

 factures are hardly known to the children of to-day. 



How much true history would be suggested by a few articles from 

 a settler's outfit of 100 years ago ? The flint-lock musket, and the 

 smooth hollowed stone used for grinding grain by hand, are almost 

 as far removed from the present as are the tomahawk and the bow- 

 and-arrow. Those who possess such relics would often be glad to 

 place them where they could be assured of permanent care itnd 

 usefulness to successive generations of children.
