i8 93 .] THE BRITISH NATURALIST. 125 



These are quoted only for the manner of filling up, I do not 

 propose to generalize on insufficient data. As a sample of successful 

 and unsuccessful sugaring I quote two forms from Mr. Mosley, of 

 Huddersfield. 



" March 28. Copse on Roadside ; Wind, S.E., slight ; Sky, partly 

 obscured, moon bright before looking at sugar ; Atmosphere, dry ; 

 Sugared about 30 trees, not before sugared, looked over once. Result: 

 Gothica, 1 ; Depressaria applanna, 3. 



April 3. Sherwood Forest ; Wind, N.W., very little ; Sky, clear, 

 but moon not risen ; very dry ; Trees, oak principally, sugar laid on 

 before dark, looked over once. Results: C. vaccinii, about 40; 5. 

 satellitia, about 20 ; T. munda, 1 ; Helops striatus, 12." 



Dr. Chapman writing on the subject gave his ideas as follows : — 

 " I am sorry to say I do not sugar now, but my recent experience at 

 sallows throws some light on part of the question. Sallows opened 

 early in March — nights fairly good (as per tradition) were more or 

 less cloudy and not cold, and moths were fairly common (20 to 50 to a 

 tree). Then came a change of weather, fine and clear, no cloud day 

 or night. As this came on the results were bad. But though the 

 weather continued clear, the days got warmer and the evenings 

 remained warm up to a certain point, and, as it happened, later each 

 evening, so that the season ended 8 p.m. on 22nd, 8-45 on 24th, the 

 last night. The moon shining brightly had no effect, and the cooling 

 by radiation taking place slowly. In other seasons, with colder days 

 and mornings, a bit of blue sky, the size of a pocket handkerchief 

 produced cooling enough to make an evening blank after the first 

 tree or so." 



I trust these extracts will assist those who were doubtful what to 

 record, but do not be solely guided by these, from which, it may 

 happen, the most important points may be excluded. Record anything 

 or everything bearing on the question, and if we do not succeed in our 

 quest, the fault will not be yours. 



General Notes. 



Moisture and Melanism. — Mr. Tutt has published in the 

 " Record," a very characteristic reply to my article on this subject. 

 He has been, no doubt, well advised, to print it where the original 

 article had not appeared. A rejoinder to the augumentative portion 

 will be prepared in due time. — John E. Robson, Hartlepool.
