testing of each patron’s milk is done every day, the dipper

being delivered, the dipper may be found to work better than 
the sampling-tube, as the cream in some cases may be so viscous 
that it will adhere to the sides and ends of the tube, and in

- A patron who delivers 200 pounds of milk testing 3% fat one 
day may on another day deliver 100 pounds of milk testing 
5% fat. If a dipperful is taken from each for a composite
