About three to four weeks is required to force the 

 plants into bloom with the temperature recommended 

 below. The first days after bringing the plants into the 

 forcing room, a temperature of 55-60° may be given, 

 gradually raising to 78-88° and maintained as equally as 

 possible until the panicles are fully developed and the 

 first flowers begin to expand; then the temperature is 

 lowered to 60-66°, and when the panicles are about half 

 open the plants are transferred to a cool greenhouse. 

 Hardening-oif is essential to ensure good keeping quali- 

 ties of the flowers. The red-flowered varieties are often 

 forced in darkened rooms in order to have the flowers 

 blanched or only slightly colored. The shade of color 

 depends entirely on the time when full light is given 

 and also on the temperature. Show plants in pots 

 should be grown in full light to have the foliage well 

 developed. While the temperature is higher than 76°, 

 frequent syringing is necessary. It is, of course, pos- 

 sible to force Lilacs in a lower temperature, and this 

 will be even advisable if the longer time required does 

 not count. Full advice for commercial Lilac forcing 

 is given by Fr. Harms in "Flieder und Asparagus," a 

 book devoted almost exclusively to Lilac forcing. 



Interesting experiments recently conducted have 

 shown that the Lilac is more readily forced when the 

 plants are subjected to the influence of ether during 

 forty-eight hours shortly before forcing. An account 

 of these experiments by W. Johannsen is entitled 

 " Das yEtherverfahren beiin Friihtreiben mit besonderer 

 Beriickrichtigung des Flieders." That the ether has a
