RECORD CMP EXPERIMENTS WITH WINTER WASHES. 
Date* of. and conditions following treatment. — The applications were made at four 
different times, as follow-: 
The first series was made on October 25 and 26. 1*91. ;uid comprised experii 
1 to 5. The trees at this time were still in leaf, but the foliage was mature and 
ready to fall. 
The second series was made November 17. and included experiments Sub- 
sequent to these applications scries 1 and 2) the weather condition- were very 
favorable, no rains occurring for some days, and in fact the months of ' October and 
November, 1894, were exceptionally dry. 
Unless otherwise noted, the applications were all made to peach tre 
Whale-oil soap. 
Experiment 2 : 
October 25. 3 pounds soap to the gallon of water: November 17. fatal to all 
scales: December 16, above result confirmed by subsequent examination: 
May 4. no living scales found on tree, nearly all dead scales washed off by 
action of rain : tree in exceptionally vigorous condition, and with luxuriant 
foliage, but with only one or two fruit set. Adjoining trees in full fruit, but 
very much inferior in general appearance and in development of foliage. 
Experiment 1 : 
October 25. 2 pounds soap to the gallon of water: November 17. fatal to all 
scales; December 16, same result confirmed by additional examination: May 4. 
1895. tree in exceptionally vigorous condition, but without fruit. 
Experiment 43 : 
January 24. 1895. same strength as preceding: March 11. fatal to 95 per cent of 
the scales: May 4. 95 per cent of scales on living portion of tree killed. Half 
the tree dead, evidently from the scale, with which it was thickly incrusted. 
Living portion of the tree in full leaf, but without fruit. 
Experiment 10: 
December 15, 1£ pounds to the gallon: January 17. fatal to 90 per cent of the 
scales : March 11, 5 i>er cent living : May 4. not above 5 per cent of scales living. 
Tree in leaf and healthy, but without fruit. 
Experiment 34 : 
January 23, 1* pounds of soap to the gallon: March 11. fatal to 90 per cent of 
the scales : May 4, less than 5 per cent of the scales living: only 2 healthy 
scales found. Tree originally very heavily infested; some of the branches 
killed, evidently from the effects of the scale: others vigorous, but without 
fruit. 
Experiment 46: 
January 24. same strength as last: March 11, fatal to 90 per cent of the scales: 
May 4, tree dead, with the exception of two vigorous branches or new shoots 
of last year's growth. On these branches 10 per cent of the scales are living. 
Experiment 35 : 
January 23, 1~ pounds to the gallon : March 11. fatal to !»0 per cent of the scales ; 
May ;. ."> per cent of the scales living, limited to terminals. Trees vigorous 
and in fruit. 
Experiment 11: 
December 15, 1 pound of soap to the gallon of water: January 17. fatal t<> 80 per 
cent of the scale> ; March 11. but 10 per cent of the scales living: May i. In per 
cent of the scales alive (on terminals . Tree in good condition ami in fruit. 
Experiment 1 1 : 
January 24, same strength as last; March 11. fatal to at least 7i> per cent of 
scales: May 4, 85 per cent of scales dead. Tree in vigorous condition, with 
fruit.
