handled. The same characteristic attaches to the imported bulbs. 
The remedy seems to be quick drying in thin layers and a thoroughly 
aerated pack. 
GOLDEN SPUR 
Golden Spur (pi. 3, C) may be considered one of the most important 
items in the Dutch daffodil list, but it is usually considered exacting 
in its cultural requirements. There are many failures with imported 
stocks. In this country experience with it has been varied and often 
unsatisfactory, but when sound bulbs of suitable size are produced 
they behave normally under glass. 
In these experiments the forcing trials of Golden Spur have, on the 
whole, averaged as good as those of any bulb handled. There will 
be no difficulty with the forcing of any sound and sizable Golden 
Spur bulbs. The difficulty, if any, lies in the growing of the stocks 
to normal size and firmness. 
To produce good stock may be a little more difficult with this 
than with the more robust varieties. When, however, the required 
conditions are provided, success usually follows. The writer has 
seen some eminently successful cultures of Golden Spur in the 
Pacific Northwest on low-lying, moist, well-drained, fertile, deep, 
sandy loam soil. The experience of the department with this variety 
on a silt loam underlain with clay at a depth of 14 inches has been 
unsatisfactory. The bases have gone out of the bulbs, causing a 
great deal of rotting. But the same deteriorated stocks have re- 
covered when culled and planted in a better drained situation. It 
is believed that the conditions for the culture of this variety must 
be more carefully considered than for most others. When suitable 
conditions are provided, as good success follows as with the hardier 
forms, except that Golden Spur is slower in reproduction. There 
is also a greater difference in stocks than with almost any other 
variety. Some importations behave much more satisfactorily than 
others under both field and greenhouse culture. 
A sandy loam soil seems advisable for the production of this 
variety on account of greater ease in handling and the more cer- 
tain drainage, but it is by no means proved that heavier soils will 
not produce good stocks if the climatic and drainage factors are 
suitable. One instance is known of good results on a rather stiff 
clay soil through which water passes readily. There is still much 
to learn regarding culture of this variety. 
PAPERWHITE GRANDIFLORA 
As may be seen from Table 3, the quality of the bulbs of Paper- 
white Grandiflora (pi. 5) which were received was very variable. 
This was easily predicted from the appearance of the bulbs at potting 
time and was made a matter of record in the case of No. 18. This 
grower sent in five bulbs as samples of stocks grown in 1925. Two 
of the bulbs were pronounced planting stock, two others commercial, 
and one very large one was of entirely different appearance. The 
two " commercial " ones blossomed, and the large one threw up a 
flowering stalk but its florets blasted. It was not a Paperwhite. 
The two " commercial " bulbs were 13 to 14 and 14 to 15 centimeters 
and gave 10 and 18 florets, respectively.
