There are many plants which furnish nectar in the various 
portions in the valley and if the apiary were moved 
northward the bees often would leave behind them a honey- 
flow from another source. If migratory beekeeping from 
south to north and then back south with the closing season 
proves successful it will probably be within the nectar-secret¬ 
ing area of a single species of plant or perhaps of two species, 
one for each direction of the journey. The Mississippi River 
plan was tried several years ago on a rather extensive scale 
without success. 
The experiment of moving an apiary south for the winter 
for the purpose of making increase has recently been tried. 
If one is raising bees for sale and has a heavy demand for 
colonies that may pay but the chances of success in following 
this plan for honey-production are small. 
The limitations of migratory beekeeping, in so far as 
present successes indicate them, have not been previously 
pointed out. They are approximately as follows: The 
movement of bees must not be from one general region to 
another, as from the white clover region to the alfalfa region, 
but from a location where the flora is that of the general 
region to a restricted region where the honey-flow comes at a 
different time, usually later. For example, it has been found 
profitable to practice the following plans in migratory bee¬ 
keeping:- (1) from white clover to sweet clover, buckwheat, 
Spanish needle or heartsease, (2) from sage to bean or (3) 
from one of the restricted regions in the South to another. 
As previously mentioned, the honey-flow at the temporary 
out-apiary usually comes after the main honey-flow at the 
permanent apiary. In most such cases, the conditions 
demand the production of extracted-honey, as comb-honey 
production and migratory beekeeping are not well suited 
to each other. 
In considering the possibility of migratory beekeeping 
it must be decided whether it is desirable to move the bees 
or simply the beekeeper. In other words, if the trip is a 
long one involving considerable expense and danger of loss
