To furnish a basis for a comparison more accurate than that shown 
in Table ITI, a special effort was made in 1920 to obtain a fair com- 
parison of dry-raked and dry-picked cranberries with water-raked 
berries handled in different ways. The berries used in the various 
comparative tests were of the same variety and were gathered from 
the same sections of the marsh. The harvesting, drying, storing, and 
packing were all done under the close observation of one of the writers, 
and careful note was taken of the length of time the berries were 
submerged and the time occupied by the various lots in drying. 
Because of the importance of weather conditions in drying water- 
raked cranberries, the weather data for the period during which the 
harvesting tests were carried on are presented in Table IV. These 
data were taken with standard instruments of the United States 
Weather Bureau by the local observer, Mr. C. L. Lewis, jr.

Up to September 18 the weather was particularly favorable for 
drying water-raked berries. Not only was it warm and dry, but 
there was a strong wind. Wet berries placed in the drying crates at 
10 a. m. were dry to the touch at 5 p.m. It is, then, not surprising 
that under these conditions the best results were obtained. 
Most of the experiments were made with berries from the marsh at 
Beaver Brook, Wis. This locality is especially favorable for the work,
