the diverting ducts and funnel, to fall into the lower pan through 
a protected opening. The lower pan, also shown in figure 5, is a 
simple receptacle with a handle and a pouring spout. 
Three detachable legs are provided to carry the lower eibeice 
and on these legs are supports for the upper pan. 
The device can be made of brass or block tin, but the material 
used must be of sufficient stiffness to resist bending or denting under 
working conditions. 
The primary purpose of this device is to divide an original sam- 
ple into smaller portions, which may be analyzed without the undue 
loss of time incident to handling a large sample, and to make this 
division in such a manner that each small portion will correctly re- 
tain the original proportion or percentage of the various factors

comprising the original sample. If the correct proportions of the 
original factors are retained, it is not an indication of failure on the 
part of the device if the grain or other material is not divided into 
absolutely equal parts every time it is run through the sampler, the 
essential feature being the retention of the correct proportion of the 
factors of the original sample. 
OPERATION. 
After the device is set up with the cylinders, legs, and pans in 
correct position, and the gate in the hopper closed and locked, the 
sample to be divided is poured into the upper hopper. 
Then the gate should be opened and swung clear of the opening, 
that the sample may fall through the opening in the hopper onto the 
point of the cone, where it slides over the entire surface of the cone
