Apparatus for this work consists of an umbrella, beating cloth or 

 other device, which is held beneath a limb or shrub and the latter jarred 



by means of a stick or by shaking, thus causing the insects to fall from 

 it upon the collecting surface beneath, where they arc captured. 



729. THE UMBRELLA. 



A common umbrella may be used for- this purpose, or one specially 



constructed with a joint near the middle of the handle to facilitate its 

 being held beneath branches and to allow of its being packed into 

 small compass. 



730. THE BEATING-CLOTH. 



This is used as a substitute for the umbrella, and consists of a stout 

 cloth, a yard square, with a loop of strong twine sewed in at each cor- 

 ner. Two straight sticks to hold it expanded are placed crosswise and 

 fastened to the loops, by which means the cloth is kept outspread. 

 When not in use it can be folded up into small compass. 



731. THE MARX UMBRELLA NET. 



This net is made from an old umbrella, and two steel rods rttached 

 to an umbrella handle at the top and to a sliding ferule at the bottom, 

 constitute the ring. The net is a shallow bag of cloth. When in use 

 the ferule is slipped up the umbrella handle until it catches behind a 

 lip, forming a circle, and when not in use it is allowed to slide back 

 and resume the shape and size, with the net wound about it, of an 

 ordinary unbrella. It is used in beating, and also serves for sweeping. 



732. THE SIEVE. 



This is a most useful apparatus, and is employed for collecting in- 

 sects which are harbored by grass, leaves, or rubbish. The ordinary 

 sieve will answer the purpose, or one specially constructed as in the 

 example exhibited. It is used over a cloth or paper. 



733. THE BAG SIEVE. 



Two brass or steel rings, one of which is covered with wire gauze, 

 are attached to the top and bottom of a strong cloth bag 12 or 15 inches 

 long. Leaves or rubbish are placed in the bag, which is then shaken 



over a collecting cloth, as with the ordinary sieve. 



734. THE HAVERSACK. 



The ordinary willow bag or basket used by anglers will serve the ento- 

 mologist to transport the various collecting bottles and apparatus 

 which it is necessary to take on excursions. Such a one is exhibited.
