APPENDIX. 163 



Another and the principal cause of confusion and misunder- 

 standing has been the many systems employed by the different 

 factories for applying the test in a practical way, and as it is 

 evident that this will soon be the universal method of paying for 

 cream and milk it seems absolutely essential that some good and 

 uniform system should be adopted. 



The object of this bulletin therefore, is to present what we 

 consider the best system for this important work and which is, 

 practically, the one in general use in milk gathering creameries. 

 In this system the cream is to be bought by weight as we believe 

 it simpler, more accurate and just as rapid to weigh with one of 

 the spring scales which can be found in most hardware stores, than 

 to measure by any system now in use. 



APPARATUS FOR SAMPLING AND WEIGHING. 



Pail for Weighing .-r-Pov thxB purpose we would suggest a light 

 pail not more than nine or ten inches in diameter and eighteen to 

 twenty inches deep, having a strong bail, a lip or nose on the top 

 and handle near the bottom to assist in emptying. It should be 

 made of light material and strengthened at the top by a hoop to 

 avoid denting when being emptied and should weigh five pounds. 



This will hold easily fifty pounds of cream, which is as much as 

 the collector cares to handle. 



Scale for Weighing — There are several spring scales on the 

 market that doubtless are good for this purpose, but the best we 

 have seen is a Chatillon spring scale that has a dial and will weigh 

 up to sixty pounds. 



The indicator can be set back so it will stand at zero when the 

 pail is attached. The figures to which it points after the cream is 

 put in will be the weight of the cream. 



This scale is compact and can be carried in a box eight by 

 fifteen inches. In making the weighing, it can be hung on a sup- 

 port on the back of the collector's wagon or on a hook in the dairy 

 that is high enough to allow the pail to hang clear. 



Tube for Taking the Sample. — For this purpose we would recom 

 mend a metal tube about two feet long and five-sixteenths inch 

 inside diameter, provided with a stopper at the lower opening that 

 can be worked at th? top by a small rod running down through the 

 large tube.
