AND SUPER MICROSCOPE 



cat, and it can be watched spinning its web with 

 spinnerettes the size of teacups. Ants at a distance 

 of six feet are seen to be fearsome individuals, six 

 inches in length, and their tiny burdens are so 

 magnified that they appear like yule logs or goodly- 

 proportioned boulders, according to their nature. 

 At a distance of ten feet a wasp may be seen 

 scraping tiny shavings of wood from oak palings 

 by means of its jaws — shavings which it converts 

 into paper for building its nest. Very small insects 

 may be observed as they come into the world from 

 their chrysalis stage. The never-tiring jaws of the 

 caterpillar may be seen at work devouring some 

 favourite leaf — the whole action of biting and 

 swallowing the vegetable matter can be plainly 

 seen. Such interesting events as the tending of 

 green flies by ants, the leaf-cutting habits of the 

 leaf-cutter bee, and a hundred and one other events 

 are all revealed by the micro-telescope and at such 

 a distance that the living objects are not disturbed 

 in their activities, being quite unaware that they 

 are under observation. To the botanist the instru- 

 ment is no less useful. 



In various manufactures, such as ore smelting, 

 and in the manufacture of glass, china and pottery, 

 in enamelling and in certain engineering shops, 

 where it is necessary to examine material at a high 

 temperature, the micro-telescope is a great boon, 

 and, at least, is the means of avoiding considerable 

 physical discomfort. It is used also by architects 

 and surveyors for examining the condition of the fac-
