check the plants receive from lifting will induce them 

 to form new flower-buils. These plants will force with 

 the greatest certainty. It is well to allow five weeks for 

 the earliest forcing. A strong heat is necessary, he- 

 ginning at 60° for the first few days and increasing to 

 75° or 80°, with a daily watering and syringing several 

 times. After the flowers begin to open the syringing 

 can be discontinued and when fully expedient the plants 

 are better removed to a cool house, where they will 

 harden off and be much more serviceable when cut. As 

 the season advances, say March and April, less heat is 

 needed. They will then force in any ordinary house 

 where the night temperature is about 60° F. The Per- 

 sian Lilac on account of its abundance of bloom and 

 delicate truss is very desirable, but this must be 

 forced almost in the dark to produce white flowers. 

 Marie Le Graye is for all purposes the most useful 

 Lilac which the undersigned has used for forcing.
