of alfalfa hay, and one and two-thirds pounds each of rolled barley 

 and bran. She was also fed daily one and two-thirds pounds of 

 the rayless goldenrod meal, which was mixed with the bran and 

 rolled barley and bran and one pound of rayless goldenrod meal, 

 no change in the animal. 



Following this, the proportion was changed to one pound A 

 rolled barley and bran and one pound of rayless goldenrod meal 

 of which she was fed five pounds daily, the alfalfa being continual 

 as usual. The mare refused to eat this mixture at first, but picked 

 out as best she could the rolled barley. Later she ate it, but some 

 of it was usually left in the box. This was cleaned out each day 

 and weighed back. There was still no noticeable change, but the 

 mare appeared very hungry. 



After three weeks with the abOve feed, the mare was given 

 one pound of alfalfa hay twice daily and all the rayless goldenrod 

 meal she would eat, with no other feed. Less of the rayless golden- 

 rod meal was eaten with this ration than formerly and, later, a 

 small amount of bran was added. With this the mare was eating 

 daily about two pounds of rayless goldenrod meal, along with the 

 two pounds of alfalfa hay and the small amount of bran. Though 

 she disliked the goldenrod meal she ate it, but showed no symptoms 

 of poisoning. The experiment closed June 30, the mare having 

 eaten altogether about 150 pounds of the rayless goldenrod meal. 

 At this time she had completely shed her coat, which originally 

 was rough, and she looked sleek and glossy. She was also lively 

 and to all appearances in good health. During the experiment she 

 lost about five pounds in weight and her breath, urine, and faeces 

 smelled strongly of the rayless goldenrod. 



Since but one animal was used in the experiment, the results 

 are not conclusive. There is no suggestion, however, that the large 

 amount of rayless goldenrod consumed was injurious to the mare. 

 It is possible that the alfalfa, bran, and barley helped her to throw 

 off the effects of any poison present. 



NOTES ON PLANT INTRODUCTION WORK 



No planting of note was done in the introduction gardens dur- 

 ing the year. This was due in part to a shortage of funds. A 

 considerable number of the plants in the garden have made good 

 growth and give promise to become valuable plant introductions 

 In December, 1919, upon invitation from Mr. Walter T. Swingle 

 of the Department of Agriculture, the writer made a trip to
