yellow in color and about the size of fly specks. Though they are 

 not known to the average grower, they are plainly visible to the 

 naked eye and may be easily found when present in any abundance, 

 by turning over the vines in the fall or early spring and examining 

 the under sides of the leaves carefully. As the eggs usually turn 

 dark colored just before hatching, this change marks the time when 

 spraying should begin, and can be watched for. If one is un- 

 acquainted with the appearance of the eggs, he will have a fairly 

 satisfactory forewarning, in the case of the second brood, by means 

 of the few tips which become spun up in advance of the rest. 



Reco)nmendations for treat7}ient : — 



A. On bogs with winter flowage and sufficient water supply- 

 to reflow once or several times : — 



i. Draw off the winter fiowage before or by the middle of April, 

 allowitig the 7Von>is to Iiatcli jiormaUy and proceed in their develop- 

 ment. 



2. Jf the worms be allowed to 7naturc in this way, luithoiit anything 

 being done to prevent their zuork, they will, in many cases, do severe in- 

 jury. To reduce this, spray with arsenate of lead at the rate of seven 

 pounds to fifty gallons of water 7'ery late in April or early in May, 



If the grower knows the fire worm eggs, he can regulate the time of 

 his spraying to suit their hatching. 



3. Do not reflow for any reason whatever until the zvorms begin to 

 come doiun out of the 7^i7ies to pupate. IV hen this happens, put on the 

 water for two or three days. 



4. I?i timing the refloto, watch carefully any Jreshly sanded spots 

 which may be present on the bog or any spots on which the vines, 

 for any reason, get an earlier start than elsewhere, for it is on such 

 spots that the worms may be expected to reach maturity first. 



5. IJ trouble zvith the second brood is expected, spray as soon as the 

 eggs begin to hatch or the first spun up tips are seen, with arsenate 

 of lead of the strength recommended for the frst brood. 



B. On dry bogs and bogs having winter flowage only : — 



I. As in most cases bogs which have only water enough for win- 

 ter flowage become uncovered more or less before the season becomes 

 far advanced in the spring, because of seepage, evaporation, etc., the
