THE SCURVY BARK LOUSE. 



THIS native of America rejoices in the scientific name of As^oidiotus 

 Harrisii, or CMonaspis furfurus, and is shown as attacking an 

 apple or pear tree. The scale of the female is oblong in form, pointed 

 below, of a greyish-white colour, and about one-tenth of an inch 

 long ; that of the male is smaller and narrower, being not more than 

 one-thirteenth of an inch long. The scales are formed by a secretion, 

 and under them the female lays her eggs. When hatched, these, after 

 a few days' activity, attach themselves to the bark, forming also a scale. 

 They do not thus disseminate, but are transported into orchards in 

 young trees. 



The Trade in Wooden Shoes. — A factory has just been opened 

 at Danbury, Conn., for the manufacture of wooden shoes. The 

 proprietor is a German, and for some time has supplied the brewers 

 in New York with wooden shoes for their employees, and the demand 

 lias become so extensive as to require much greater facilities and 

 the aid of steam-power. The shoes have the improved curved round 

 toe of the old Dutch style, and are heelless. They are made wholly 

 of the wood of the butter-nut tree, and while impervious to water, 

 are also very light. They have been introduced into all the hat 

 shops for the protection of the feet of operatives from the wet floors, 

 while at the same time they are very easy and rest the feet.
