The following Tables are the day and night temperatures recom-

The temperatures recommended by Mr. David Thomson do not 

 greatly vary from these. To succession-plants, for the first four 

 months in the year, he allows a range of from 55 to 75. For fruiting- 

 plants the range for the same period is 65 to 75. The summer 

 temperature is higher, reaching for fruiting plants to much more in 

 May, when from 80 to 100 may be permitted for these plants, only 

 however for a few hours after shutting up, falling to 70 or 75 

 by midnight. After September, for which month 65 to 70 is given 

 for succession-plants, and, doubtless, at least 5 more allowed to those 

 in fruit, 60 to 65 is quoted for October, and 55 to 60 for Novem- 

 ber and December. The bottom heat is allowed a range of from 75 

 to 90, the latter, however, being the utmost limit ; 85 is permitted 

 just after potting, to sink soon after to 80, which is a good growing
