MICROSCOPE IN MANUFACTURES 



know that the reason why some people do not grow 

 very much is because they are delicate, ill health 

 affects the whole system. The constrictions in the 

 sheep's wool occur because the animal has suffered 

 from some illness, or from great hunger or thirst, 

 which has resulted in its wool not growing properly 

 for a period corresponding to the duration of the 

 illness or other calamity. 



The examination of various animal hairs will help 

 to while away many an hour and many of these 

 objects are of the greatest interest. If we have the 

 opportunity it will be interesting to compare the 

 wool from different kinds of sheep, that from the 

 Lincoln sheep, for example differs from that of 

 shortwooled kinds. We may also compare goat's 

 wool with sheep's, then there are differences be- 

 tween the hair of cows and calves. Comparisons 

 always make microscopic work more interesting. 



The microscopic examination of cloth, used for 

 making our coats, is quite interesting work and 

 withal important. A good deal of the cloth which 

 is made up into suits is known as shoddy, that is 

 to say that material that has been worn before; 

 old rags of all sorts and many other extraordinary 

 things go to the making of this cloth. There are 

 special factories to which rags are sent to be made 

 up into shoddy. One might think therefore that 

 this substance would be easily recognised under the 

 microscope but it is not quite so easy as we shall 

 see. Absolutely pure wool from the sheep giving the 

 best quality wool is only used in the very finest
