SHORTAGES! 
Because of unusual flood conditions in California nearly 
all the past winter and the blocking of foreign supplies, 
a few flower seed items for this season might be short. 
Our connections thruout the seed world will enable us 
to supply all available lines, and the chances are the 
few shortages will not be serious. 
As we go to press our greenhouse seed crops of such 
valuable items as non-branching Stock, forcing Snap¬ 
dragons and such others that can be produced to ad¬ 
vantage in our greenhouse, promise to be in normal 
supply. We must learn to adjust ourselves to these ab¬ 
normal times. We’ve gotten along very well with few 
or no Dutch bulbs; so, please bear with us if a few 
flower seed items must be cut out.

HAVE YOU A CROP PROBLEM? 
Picturing one half of our 300 ft. bed used every day of the year 
for seed testing. Note this is done in soil. Various bottom tem¬ 
peratures are maintained for the cool and warm crops. Also when 
a valuable lot shows up poor, it is tested over three times. Fre¬ 
quently a second test, under apparently identical conditions, will 
show a poor lot coming well. Why? just one of those numerous 
scientific problems our business is full of. But when a lot of seed 
comes from this bed marked O.K., you can depend on it.
