be more than one inch in thickness ; bake them in 

 an oven about twelve hours when the temperature 

 is equal to that just after it has been used for 

 baking bread ; they must not be burned * : this, 

 chopped as before directed, with equal parts of 

 rotten manure, forms one of the very finest of com- 

 posts. The plants must be looked to carefully in 

 spring, and whenever infested by the aphis, or 

 green-fly, tobacco-smoke must be applied : extra- 

 ordinary luxuriance of growth may be given by 

 watering them once a week with guano-water. 



A season may be saved in the growth of these 

 roses if plants in larger pots than those they are 

 usually sold in are purchased: if these are pro- 

 cured in the autumn or winter, they may be 

 placed in the greenhouse at once with a cer- 

 tainty of succeeding. 



CULTURE OF HAEDY ROSES IN POTS 

 FOR EXHIBITION. 



The most elegant pot roses for exhibition may 

 be selected from those families recommended for 

 greenhouse culture ; but as it is now the fashion 

 for Horticultural Societies to offer prizes for f( roses 

 in pots," it becomes my duty to offer a few obser- 

 vations on growing hardy varieties of roses in 



* I have used, with much success, turf roasted on a sheet of 

 iron (placed in temporary brickwork) under which a moderate 

 fire has been kept : about one hour's roasting is sufficient. This 

 chars the turfy side, and acts most beneficially.
