Improving the Hog's Table Manners 



MORE attention is given to the care 

 and feeding of hogs than ever 

 1 efore, but while the composition of the 

 rations has been improved, there has 

 been no breed of hogs developed even 

 among the aristocratic prize winners, 

 whose table manners are essentially 

 different from those of the plebeian. 



If the hogs could not reach the trough 

 until the food had been poured into it 

 and evenly distributed, the feeding 

 process would be simplified. This may 

 be accomplished by applying the method 

 suggested by the accompanying illustra- 

 tion, in which it will be seen that a 

 section of the fence is cut out to receive 

 the trough and gate. The latter, swing- 

 ing from the top at E, is held at the in- 

 side edge of the trough by the button D, 

 as indicated by the dotted lines, which 

 permits the feed to be poured into it. 



The bottom of the gate may then be 

 swung outward and lieJd in place at the 

 outer edge of the trough by the button 

 at A, as shown by the full lines, whi.li 

 will allow the hogs to reacli their li'cd. 



The stops B, B, upon the outside of 

 the fence, and C, upon the inside, pre- 

 vent the gate from being opened.

How to Make an Oil-Filter 



A SIMPLE oil-reclaiming outfit may 

 be made from a whole barrel and a 

 half barrel. A funnel, terminating in a 

 perforated pipe, is attached to the rim 

 of the whole barrel as shown in this illus- 

 tration. Water is placed in the upper 

 compartment. If the filter is used where 

 a stream of hot water or steam can be 

 utilized, it will im- 

 |:)rove the action of 

 the filter. In that 

 case, place a loop of 

 the pipe in the side 

 of the barrel and keep 

 the temperature of 

 the water near the 

 boiling point. 



When the oil rises 

 to the top of the 

 barrel it overflows 

 through the pipe at 

 the left into the part 

 below, where it passes through a strainer 

 made of two thicknesses of cheesecloth. 

 The complete outfit can be enclosed 

 neatly and compactly in an outer cover- 

 ing of boards to represent a cupboard. 



The oil reclaimed by this filter is good 

 enough for all ordinary speed shafts or 

 bearings. Accessories, such as a water 

 overflow and draw-ofT valve, etc., for the 

 top barrel, will suggest themselves to 

 anyone sufficiently interested to con- 



The food can be 

 placed in the 

 trough without 

 the annoying 

 interference of 

 impatient hogs

String Holder and Cutter 



A NOVEL device in the shape of a 

 convenient holder and cutter for a 

 h.ill of cord is here illustrated. Tiie 

 cutter is made in tlie shape of a sheet- 

 metal collar with partly overlapiping 

 ends, these being 

 sharpened so as 

 to cut the cord. 

 T h e c o r d i s 

 brought through 

 a pair of holes in 

 the cutter so that 

 after the cord is 

 cut the loose end 

 lends to (ly up, owing to the elasticity 

 oi the string. The end then lies above 

 the cutter where it can be easily grasped. 

 The cutter piece is attached to the string 

 box by a pair of sheet-metal anns.
