CHANGES IN PHYSICAL APPEARANCE. 



On receipt of the various samples of hops from Perkins, Cal., in 

 1911, they were examined and the following notes taken respecting 

 their physical characteristics : 



Sulphured hops in the original lot. — Fine fresh, hop flavor; oily feeling; lupulin 

 sticky; aroma excellent; color bright, characteristic of new fresh hops; color of 

 lupulin bright. 



Unsulphured hops in the original lot. — Fine fresh hop flavor; oily feeling; lupulin 

 sticky; aroma excellent; color bright, characteristic of new fresh hops, though some- 

 what greener in appearance than the corresponding sulphured sample; color of lupulin 

 bright.

 notes were taken on their physical characteristics:
