drive on the stock and then balance 

 the scale "high." 11 the scale is slug- 

 gish he can easily defraud the seller 

 out of from 10 to 15 pounds on weigh- 

 ing, -which is a very appreciable 

 amount when a single calf or hog is 

 weighed. 



The beam of these scales should be 

 provided with a shoulder stop to pre- 

 vent the sliding poise from moving 

 back of the zero graduation. Instances 

 are on record where this shoulder stop 

 has been filed so that when the scale 

 is .brought to a balance with the poise 

 back of the zero graduation and later 

 used in weighing the buyer will be 

 paying for less than the actual weight. 



Various devices have been used 

 that will produce an upward push on 

 the platform, working directly against

To find contents of square cistern, multiply length by breadth and multiply 

 result by 1.728 and divide by 231. Result will be the number of gallons for 

 each foot deep. 



5 feet by 5 feet has capacity per foot depth of 5.92 



6 feet by 6 feet has capacity per foot depth of ^8.54 



7 feet by 7 feet has capacity per foot depth of 1 1 . 63 



8 feet by 8 feet has capacity per foot depth of 15 . 19

the downward pressure of the load. 

 According to railroad employees, a de- 

 vice of this kind was aattached to a 

 stock scale in a city inr the western 

 part of Wisconsin. Two vertical 

 boards were nailed to the ends of a 

 2 by 4 scantling that rested in a hori- 

 zontal position on the foundation of the 

 scale, thus forming a lever. One end 

 of this device projected upward be- 

 neath the platform of the scale to 

 within a fraction of an inch of the 

 platform. The other end projected up- 

 ward through the floor in front of the 

 beam box so .that the stock man in 

 weighing could press down on the 

 same with his foot, thus decreasing 

 the weight of the load to the extent 

 desired. Similar devices are said to 

 have (been, used by some wfheat buyers 

 in our own western provinces. 



10 feet by 10 feet has capacity per foot depth of 23 . 74
