EXPERIMENTAL WORK WITH CRANBERRIES.

Tliorough spraying with a 20 per ci^nt. iron sulphate solution was fairly 

 effective in killing back the tops of the weed, but there is, as has been 

 already noted under the fruit-worm discussion, a possible danger connected 

 with the continued use of this chemical on the same area. 



9. RESANDING. 



Plots and V, spoken of in last year's report, were again left without 

 resanding this year, while the surrounding bog was also not rcsanded. 

 Three new plots, N, R and T, were laid out and resanded on Oct. 17, 1912, 

 while the surrounding bog was not resanded again. All these plots were 

 picked with scoops in 1913, and checks on each were laid out and picked 

 for comparison. The following table is, in this connection, self-explan- 

 atory : —

It will be seen from the above table that plots and \ showed a dis- 

 tinct falling off in quantity of fruit, due to the prolonged lack of resanding. 

 Plots N, R and T, however, gave no increase in fruit over their checks, 

 probably because the previous resanding of the general bog (fall of 1911) 

 was still sufficient to maintain the vines in very good condition. Berries 

 from all these plots and their checks were tested for keeping quality, the 

 period of storage extending from October 28 to about December 20 on the 

 average, there being a variation of five days in the time of final screening.
