ys 
ry of Sassenheim, treated similarly, "showed no detrimental effects in 
the flowering, but one sample from a commercial lot showed a very low 
percentage of bloom." In the time series, in which a censtant temper-— 
ature of 111° F. was maintained and the bulbs exposed for periods of 4, 
6, 8, 10, and 12 hours, on August 24, 1931, Victoria bulbs "showed 
about the same grade of flower throughout. Bulbs receiving longer treat— 
ments bloomed a little earlier." In the temperature series, in which 
bulbs were treated for 4 hours at varying temperatures--110°, 111°, 112°, 
113°, 114°, and 115° F.—-on August 29 and 30, 1931, the results of Victo-— 
ria bulbs were "a slightly shorter growth in bulbs treated at 115° and 
above, also a slightly lower grade of flowers in bulbs treated at higher 
temperatures. Otherwise the series was about normal." Bulbs of the 
Emperor variety "showed effects paralleling those in Victoria," while 
"two samples from commercial loads (treated for 4 hours at 111° F.) 
showed complete reversal of each other. One sample was more vigorous than 
the untreated and produced grade 2 flowers. The other treated sample 
was much weaker than its check, many bulbs not producing a flower. The 
reason is not evident for this." In the weekly fumigation series vari- 
eties treated with the standard dosage (7 ounces sodium cyanide per 1,000 
cubic feet for 4 hours) and showing no injury were: Victoria, Emperor, 
King Alfred, and Laurens Koster.
