92 Report oF THE DEPARTMENT OF ANIMAL HUSBANDRY OF THE 
time. Lots V and VII averaged one-half pound in weight over 
a week sooner than Lots VI and VIII and Lot IX over two 
weeks sooner than Lot X. The average weight of one pound 
was reached by Lots I and III about a week sooner than by Lots 
II and IV, the average weight of 1.5 pounds three and one- 
half weeks sooner, and the average weight of 2 pounds four and 
four-fifths weeks sooner. The average weight of one pound was 
reached by Lots V and VII two weeks sooner than by Lots VI 
and VIII, the average weight of 1.5 pounds over three weeks 
sooner, the average weight of 2 pounds three and three-fifths 
weeks sooner, the average weight of 2.5 pounds over four weeks 
sooner. The average weight of one pound was reached by Lot 
IX three weeks sooner than by Lot X, the average weight of 1.5 
pounds three and four-fifths weeks sooner and the average weight 
of 2 pounds three weeks sooner. 
EXPERIMENT WITH DUCKLINGS. 
In the experiment with ducklings the birds in the two lots 
were all Pekins. Lot A had the rations mentioned on page 77 
containing animal food and Lot B the ration of vegetable food. 
These rations were fed unchanged during the first month. It 
was then evident that the one ration was very deficient in some 
respect, for before the end of the fourth week one-half of all the 
birds in Lot B had died. Animal meal was then added to the 
ration, otherwise unchanged, for three weeks and then for two 
weeks longer the original ration was fed. Only one bird died 
after the first change in the ration. None died in Lot A. After 
the ten weeks Lot B was fed for five weeks on the ration which 
had been fed to Lot A, and Lot A was also fed the same ration 
for three weeks longer. The tabulated data follow:
