♦ The kilogram equals almost exactly 2.2 English pounds. 



The above weights were taken after the tubers had been 

 carefully washed and dried. They showed a range of varia/- 

 tion amounting between halves to a little over 37 per cent., 

 and between tubers of about 22 per cent. The diflerences 

 in number and size of tubers are equally striking. In view 

 of these facts, I submit that variety tests of potatoes upon a 

 small scale can have but a small value for determining the 

 probable relative yield of varieties. 



Poultry Experiments. 

 The experiments with poultry completed since our last 

 annual report were begun in the late fall of 1897, and ex- 

 tended through the winter of 1897 and 1898, and a part of 

 them through the past summer and into the fall. The points 

 upon which these experiments were designed to afford in- 

 formation are the following : — 



1. Effect upon egg-production of the use of condition 

 powders. 



2. Comparative value for egg-production of flesh or 

 animal meal and cut fresh bone. 



3. Comparison for egg-production of a wide nutritive 

 ration with a narrow ; or, in other words, of a ration in
