Second Report on Economic Zoology. 
to beat the hedge and also the ivy on the stable-yard wall for nearly two 
hours, but did not see another Culicid. 
“Tub in orchard for cattle to drink from, filled from standpipe: 
Clean — no Culicids. 
“ On the second visit — also a scorching hot day — I made the round 
of the collections of water tested and treated on the first visit, but no 
signs of the enemy. Afterwards, I extended my work to the shrubbery 
and wood, and made my first discovery of adult mosquitoes in numbers, 
in an earth closet close to the Hall, the roof and ceiling of which were 
covered with hundreds of Gulex pipiens, all sluggish females with distended 
abdomens. The next capture was a female of Grcibhamia dorsalis at rest 
on the side of a manhole near the Hall ; the male escaped. 
“ In the wood which adjoins the gardens and extends for about half 
a mile to Higham Lake, I saw first a few of the ‘ Wood Mosquito ’ ( Gulex 
nemorosus ), and individuals of the ‘ Banded-legged Mosquito ’ ( Gulex 
cantans ) ; then, as I proceeded towards the pools by the Lodge and 
Higham Lake, their numbers increased to such an extent that, when 
forcing my way through the bracken — shoulder high in places — in search 
of their breeding pools, the Culices rose in clouds and attacked me so 
viciously and persistently that I had to cover my head with my net. 
While testing the pools for ‘ egg-rafts ’ and * wrigglers ’ of these two 
species, the bloodthirsty creatures bit all exposed parts, and, moreover, bit 
either through my flannels or crawled under to do so. Over fifty hard 
bumps the size and shape of a split pea marked where they had punctured. 
As the only inconvenience was an irritation, particularly after washing and 
shaving, no remedy was applied, and in the coarse of a week they had all 
disappeared. 
“No traces of mosquitoes in any aquatic state could be found in either 
the large open pool near the Lodge or the small ones surrounded with 
dense undergrowth in the wood. Nevertheless, all pools were treated with 
a heavy dressing of paraffin. The small pools are being filled in with 
refuse from the Hall and Lodge. 
“ The two permanent ponds in the meadow for cattle to drink from 
were inspected — no mosquitoes in any state — many Dragon-flies on the 
wing. 
“ Higham Lake — I worked unsuccessfully all round it for the larvae of 
Gulex nemorosus , the adults of which were numerous and annoying on the 
banks. 
“ On the third visit — a sultry day — the cistern closed with two doors 
fitted over the servants’ entrance to the Hall was first examined — hundreds 
of the ‘ Household Mosquito ’ ( Gulex pipiens) were hanging on the ceiling, 
though a thorough search revealed no other than adult female forms. 
“ This cistern was emptied, scrubbed and flushed out, the walls and 
ceiling brushed down, then the doors closed and all open joints doubly 
papered to prevent mosquitoes entering for hibernating or egg-laying 
purposes. 
“ The large rain-water cistern on the flat leaded roof was next inspected 
— thousands of adults of the ‘ House Mosquito,’ but none of its early 
stages. 
“ Crevices and corners were brushed out and the water thickly coated 
with paraffin.
