CONCLUSIONS 
No attempt has been made in the preceding pages to enumerate 
the advantages and reasons for community production of one variety. 
A number of publications dealing with this phase of the subject 
are listed at the end of this bulletin. The objective here has been 
to describe the development of an actual one-variety community from 
a mixed-variety condition, enumerating the difficulties encountered 
and the way in which they were surmounted. Many of the advan- 
tages of one-variety production are of course mentioned, but they 
are the ones incidental to the problems encountered and are dis- 
cussed primarily from the standpoint of actual improvements 
effected. 
It might seem from the foregoing pages that the production and 
distribution of planting seed has had undue prominence. The pro- 
duction of superior planting seed, however, is a necessary condition 
to the production of superior fiber, and the fact that the Coachella 
Valley Acala community did provide good Acala planting seed for 
other districts made the benefits of the community organization avail- 
able to a much wider area. Such an undertaking on the part of a 
community also provides material for a discussion of the precaution 
necessary for the production of pure planting seed. As a matter of 
fact, the returns to the Coachella Valley Acala community from the 
increased value of their fiber far exceeded the added value of the 
seed. 
In conclusion, features are briefly mentioned which were found by 
the experience in the Coachella Valley to be of material assistance 
in establishing a one-variety community. 
1. The establishment of a one-variety community will be much 
easier if a good variety is chosen, since its superiority over the poorer 
varieties can be demonstrated. For instance, the Acala variety gave 
exceptionally good results in the Coachella Valley from the first, and 
for this reason many of the growers were anxious to procure seed. 
The best variety can sometimes be demonstrated by community 
variety tests, and such data will be of influence with some growers. 
2. However, if the community is to depend on an outside source 
for its seed supply, it is important to choose only a variety of which
