WHITE PINE BLISTER RUST 109 
On this area the total averages for all types are about as 
follows: 
AREA—1192 ACRES 
Average No. gooseberries 23.1 per acre 
“currants 56.8 “ * 
‘¢ “man-hours 2.24 “ « 
“ cost eradication $1.16 “ 
Advanced scouting was not used on this area, as the number 
of Ribes was heavy and the occurrence very well distributed over 
the entire area. 
This cost includes the entire cost of maintenance for the men 
as well as salaries, and was the maximum for all of the work done 
during the season. 
A larger area about Brunswick and adjacent to the demonstra- 
tion area was eradicated by using the advance scouting method, 
and this helped considerably to reduce the cost on an acreage basis. 
THE ALFRED AREA 
On the Alfred area very careful checking was done in order to 
find out the actual results from the eradication work of the previous 
season, and to learn, if possible, what to expect in the way of organ- 
ized eradication of a large area. 
The results were about what might reasonably be expected. 
The greater part of the Ribes found this season were either young 
seedlings or sprouts from plants broken off in the eradication work. 
Of the 1528 plants found over an area of 545 acres, 1092 or 60% 
were sprouts or young seedlings of less than six inches, while 436 
or 40% were larger plants overlooked in the eradication work of 
the previous season. 
As a whole, however, the previous eradication showed an effi- 
ciency of 95%. Only 4.9% of the number of plants previously 
found were taken out during the present season’s work. 
A general summary of the work on all of the Alfred check 
plots is as follows: —
