Fig. no. Fig. 110 represents 



an aquarius, or hand 

 water-engine, invent- 

 ed by W. B. Doug- 

 las, of Middletown, 

 Connecticut, which 

 we know, from ex- 

 perience, to be an 

 excellent device for 

 sprinkling trees with 

 soap-suds, or for wa- 

 tering flower - beds, 

 and even for wash- 

 ing the outside of 

 windows. A small 

 lad can sprinkle 

 soap-suds all over a 

 tree twenty feet high 

 with such an aqua- 

 rius. The illustra- 

 tion scarcely requires 

 an explanation. The 

 nose is provided with a rose-spout, full of numerous small 

 holes, for the purpose of scattering all the liquid into spray. 

 Such an aquarius may be obtained at most hardware stores. 

 Apple-tree Worms. One of the most difficult apple-tree 

 worms to combat is the small green sixteen-legged larva, 

 nearly half an inch long, and with a broad, dark-brown 

 stripe on each side, extending the whole length of its 

 back. These depredators are found to do considerable 

 damage to the apple-tree. They are said to belong to a 

 new and hitherto undescribed species. The mode in which 

 this larva operates on the apple-tree is by tying together 

 the leaves with silken cords, forming a mass of considera- 



Douglas's aquarius.
