rery cold ; the pans of water were kept full. This treat- 

 ment was continued to— 



Januai-y 20th,—- when the temperature, in cloudy 

 ■weather, was raised to 70° by day ; during the night, 

 and on sunshiny days, the same as from the tenth in- 

 stant ; and this was continued to February. 



The vines, near the furnace, were all pushing, both 

 sets at the same time, those planted on the outside of the 

 house, and those on the inside. The mercury, in the 

 open air, last night, was at zero ; in the house, at 9, 

 P.M., it was 55° ; at 7, A.M., 48°, with as large fires as 

 the furnace would allow. 



January 25th. — Nine of the vines, which were nearest 

 to the furnace, were tied to the rods. 



January 27th.— Put up sixteen more. 



February 1st. — The temperature, at night, was kept at 

 55° to 65° ; by day, and 'when cloudy, 70° to 75° ; by 

 sunshine, 75° to 85°, giving air as above ; and this tem- 

 perature was continued until the blossom was over ; the 

 remaining vines, on the front of the house, were taken 

 up and secured to the rods. 



February 2d. — The vines, on the back of the house, 

 were tied to the trellis ; some of the shoots, on the vines 

 near the furnace, were two feet, and some three feet 

 long; they were cut back to one eye beyond the fruit. 



February 10th. — Rubbed out all but one shoot on each 

 spur, where it had not been done before ;* the spurs 

 which were cut close have generally pushed, from dor- 



* This can be done as soon as the shoots are one inch long, shortly after 

 the canes are put up.
