Copper sulphate (weak).— Auburn, Alabama. . 



Ammonium oxalate (weak). — Auburn, Alabama. 



Water. — Auburn, Alabama. 



Hydrochloric Acid (strong). — Geneva, New York. 



Water. — Geneva, New York. 



Ammonium nitrate (strong). — Auburn, Alabama: Leaf buds eased 

 January 29; leaf buds burst January 31; first leaf unfolded Feb- 

 ruary 7. 



Peach (Late Crawford). 



Twigs from the stations indicated in a previous table were placed 

 in solutions of corrosive sublimate (weak), copper sulphate (weak), 

 sodium chloride (weak), ammonium nitrate (strong), ammonium 

 oxalate (weak), potassium chloride (strong and weak), sodium bicar- 

 bonate (strong and weak), potassium bisulphate (strong), hydrochloric 

 acid (strong), acetic acid (strong), without showing any response. The 

 twigs in water eased their flower buds on January 31 and on February 

 5 the flower buds had burst. 



Peach (Oldmixon Free). — 



No response of any description of the twigs from the various stations 

 noted in the table at the beginning of the experimental record in any 

 of the various experimental fluids except water. This and the imme- 

 diately preceding series indicates that the peach is peculiarly sensitive 

 to the action of such chemicals as were used. In water the twigs from 

 College Park, Maryland, responded as follows: Leaf buds eased Feb- 

 ruary 1; leaf buds burst February 7; flower buds burst February 3. 



Pear (Duchess de Angouleme). — 



Corrosive sublimate (weak). — Storrs, Connecticut: Leaf buds eased 

 February 1. 



Sodium chloride (weak). — Storrs, Connecticut: Leaf buds burst 

 February 1 ; flower buds burst February 4. 



Potassium chloride (strong). — College Park, Maryland: Flower 

 buds burst January 29. 



Potassium chloride (weak). — Storrs, Connecticut: Leaf buds eased 

 February 4; flower buds eased January 29. 



Sodium bicarbonate (strong). — College Park, Maryland: Leaf buds 

 eased February 4. 



Potassium bisulphate (strong). — College Park, Maryland: Leaf buds 

 burst January 29.
