horses or cattle cannot push it open, for the simple reason that when they press 
the top part over the bottom of the gate rises and strikes their shins. This 
puzzles and annoys the animals, and they at once go away. In Fig. 2 this

happy effect is displayed. : 
Pedestrians carrying a burden can pass through easily enough. It is 
merely necessary to roll out the wheel a little way, when the pails or other 
burden can be carried through, a slight push with the foot being sufficient to 
close the gate. 
By grading the ground, or weighting the iron hoop, the gate can be made 
to shut automatically from any position. The whole idea is ingenious, if 
simple, and the fact that the inventor has taken out a patent for his notion 
shows that he believes there is something in it.—Furmer and Stockbreeder. 
TO TEST WATER. 
THERE is a simple test for the presence of sewage in water. All drinking 
water should be tested in town or country frequently, as there are other 
impurities besides sewage which are quite as deadly, and every cistern of water 
is lable to be a source of blood-poisoning. Mice, rats, and other pests must 
have water, and many a case of typhoid is set up by such as these falling into 
the cistern and remaining there for months in a decomposed state. ‘To detect 
this impure condition is very simple and unfailing. Draw a tumbler of water 
from the tap at night, put a piece of white sugar into it, and place it on the 
kitchen mantel! shelf, or anywhere that the temperature will not be under 
60 degrees Fahrenheit. In the morning the water, if pure, will be perfectly 
clear ; if contaminated by sewage or other impurities the water will be milky. 
This 1s a simple and safe test well known in chemistry.
