FEEDING DRIED PRESSED POTATOES TO SWINE. 3 
meal, 4 parts middlings, and 1 part tankage. The lots and rations for 
the experimental feeding were as follows: 
Lot I (check lot). — 6 parts corn meal, 1 part tankage. 
Lot II. — 6 parts dried pressed potato, 1 part tankage. 
Lot III. — 6 parts dried pressed potato, 1 part linseed-oil meal (old 
process). 
Lot IV. — 6 parts dried pressed potato, 1 part fish meal. 1 
The lots were fed three times daily (7 a. m., 11.30 a. m., and 4.30 
p. m.). For each meal the feed for each lot was weighed and put 
into a bucket with a sufficient amount of water to make a thick slop, 
this being done about half an hour before feeding, so as to allow time 
to soak. Raw steam was turned into each bucket of feed for a few 
minutes just after the feed was mixed to facilitate the soaking. A 
fresh supply of water was given to the pigs about the middle of the 
forenoon. The animals were weighed on the scales located inside 
the permanent hog house. Individual weights were taken for three 
consecutive days (one day previous to the beginning of the experi- 
ment and each of the first two days of the experiment) . The average 
of the three weights was taken as the weight of the second day, or 
the beginning of the experiment. The final division into lots fol- 
lowed the first weighing, which was on the day previous to the be- 
ginning of the experiment proper. Individual weights were taken 
every Tuesday thereafter until the conclusion of the experiment.

RESULTS OP THE FEEDING. 
The pigs in all of the lots ate well and regularly, and not one went 
off feed during the test. Small quantities of feed were left in the 
troughs after feeding time, but this was due to the fact that the pigs 
1 Fish meal is a very effective supplement to a grain ration for pigs. They are ex- 
tremely fond of it and make rapid and economical gains on such a ration. Those who 
wish to obtain further info rmat ion on the subject of feeding fish meal to live stock 
may consult United States Department of Agriculture Bulletins 378, " Fish Meal, Its Use 
as a Stock and Poultry Feed," and 610, " Fish Meal as a Feed for Swine," which may be 
had from the Superintendent of Documents, Washington, D. C, at the price of 5 cents 
each.
