THE BROOD-REARING CYCLE OF THE HONEYBEE 27 
STORES 
As already stated, none of the 16 colonies suffered from lack of 
stores at the beginning of the period of initial expansion. No data 
were obtained, therefore, showing the effect of want of stores on 
brood rearing. It was evident, however, as soon as nectar became 
prematurely available from fruit bloom, that certain colonies had 
such an abundance of stores as to result in lack of room for any 
expansion of the brood area. The history of colony No. 14 brings 
out this fact, although in this instance colony population also influ- 
enced the result. The importance of having sufficient stores in 
early spring until incoming nectar supplies the current needs of the 
colony, and the need of room sufficient to offer no check to the 
initial expansion, should emphasize to users of the Langstroth or other 
hive bodies of equivalent size 'the value of wintering a colony in two 
hive bodies, and show that otherwise a full population for the honey 
flow is liable not to be attained. 
OBSERVATIONS IN 1920 
It has been thought of interest to introduce at this point the work 
done by Lloyd K. Watson in 1920, while he was connected with the 
Bee Culture Laboratory. As already stated, through direct counts 
of all eggs, larvae, and sealed brood, he was able to obtain in that year 
a total of five seasonal brood records. (Tables 18 to 22.) It must 
be borne in mind that the curves (figs. 19 to 23) based on these 
records represent a total of all eggs, larvae, and sealed brood, whereas 
the curves (figs. 1 to 18) based on photographic records made by the 
writer represent sealed brood only. Furthermore, the curves for 1920 
are not drawn to the same scale as are the other curves in this paper. 
These differences in themselves would be sufficient to cause the 
curves to present apparent discrepancies in the time and degree of 
response even to the same stimuli. Unfortunately, too few data on 
each colony are available, other than the actual counts of brood, to 
warrant a close correlation between the brood records for 1920 and 
those already discussed. Nevertheless, the results for 1920 are in 
line with those presented for the succeeding years. 
Each of the five colonies (A, B, C, D, and E) had been wintered in 
two hive bodies in quadruple packing cases. Colonies C, D, and E 
were unpacked on March 17, while colonies A and B were left packed 
until April 13. In August, 1919, a young queen had been introduced 
into each colony. All the colonies were well provided with stores. 
In 1920, as in 1921, there was a period of cool weather during early 
April. From April 4 to April 11, inclusive, the minimum and maxi- 
mum temperature corresponded roughly with the freezing point (32° 
F., 0° C.) and the clustering point (57° F., 13.89° C.) respectively. 
In fact, with two exceptions, the minimum temperature on each day 
of this period was below 32° F. (0° C.) whereas on only two occa- 
sions does the tempera ture record for any day within this period show 
a maximum of over 57° F. (13.89° C). The two exceptions to the 
minimum are April 4, with a minimum record of 39° F. (3.89° C), 
and April 5, with a minimum record of 43° F. (6.11° C). The two 
exceptions to the maximum occurred on April 9 and April 11, the 
former having a maximum of 61° F. (16.11° C), the latter of 64° F. 
(17.78° C). The data available as to honey flows show that the 
most nectar of the year was gathered during the last half of May.
