BIRDS. — The latest of the summer migratory birds arrive in this month, and the last of those 
of winter hare left us. Tlmse which arrived last morith are now busied in the construction of 
their nests, or the care of their eggs or youn^'. The nests of the Lesser White-throat may be 
found generally in the White Rose, (Rosa arrensis -.) of the U'incliat, in hollows excavated 
in the ground ; and of the ISed^e Warbler, in the wiiluws, in the water, or in a bush on the 
bank, near to wliere the male .sits singino- his varied and imitative song night and day, ever 
watchful to apprize his mate of any ajiproacliiiig danger. 
In some of thosi' calm, mild, beautiful moonlight niah'.s,^vhich frequently occuvrn this month, 
the Cuckoo may be heard singing tor hours after every other bird is still, (except the Night- 
ingale, the Corncrake, and the Sedge Warbler,) and it frequently continues its simple song 
till morning. 
The Corncrake, Gallinula Crfx, (Ortvgo'metra Cn'x.) is the earliest visitor of the month, 
generally arriving in the first week. The Night-jar, Caprimi/lgvs evropa^^us, (Nyctichelidon 
europa?^us,) may be found in the twilight, on heaJis and among fern, pursuing on the wing 
such beetles and other insects as frcqnent those places. The Lesser Butcher-bird, I/mius 
coW«rio, makes its appearance this month, and generally for a few days after its arrival takes 
its station on the top of some high tree, where it sits repeating "its hoarse call, which is 
something similar to that of the House Sparrow, but much harsher; by this, and its short and 
interrupted flight, it niay easily be known. The Greater Pettychaps, or Fauvette, Sylvia 
hort-nsis, and the Wood Wren, Sylvia sylvicOla, (Sylvia sibilatrix,) arrive in the beginning of 
the month. The Spotted Fly.cateher, Afuscici'.pn grisoh, and the Pied Flycatcher, M. atrica- 
pilla, which may in general be considered the last of the sttmmer birds, .arrive about the middle 
or latter end of the month

FOR xMAY. 
The exceeding fine weather we experienced early in April reemed to indicate that a very for- 
ward spring might be expected ; this, however, was followed with some cold north-east winds, 
which have been of immense advantage in retarding the progress of vegetation, and preventing 
the blossoms from expanding and falling a ready sacrifice to the frosts that may still be ex- 
pected. At present the trees give flattering promise of a phutiful fruit year. ^Vall trees will 
still require protection. .Sowing and planting for successional crops are necessary to a consider- 
able extent. Insects must be narrowly looked after and destroyed. Towards the end of the 
month, Peaches aud Nectarine trees w'ill require their fore -right shoots rubbing off, and the 
side ones projierh thinning. Grapes in the stoves, or vineries, will want thinning out, and the 
young wood of the Vines tying in, and stopping. Ridges for Cucumbers should be made. 
Annuals of several sorts should be transplanted; and cuttings of many green-house plantt put 
in. Look well to the Cucumber and Melon framesj'and give green-house plants air, night and 
day when the weather is fiue, which will much prolong the flowering season. 
FKUIT DEPARTMENT. 
Protect Wall Trees in blossom. — See Calendar for March. 
Apricot Trees will now require examining, and the Caterpillars secreted in the buds, destroying. 
See Calendar for April. 
Peach Trees in houses, started in December, will now be swelling up. Keep the heat from 
70 to 75 by day, and 65 to 70 by night. Steam the houses regularly, and syringe the trees 
occasionally, until the fruit begins to ripen, when it must be discontinued. In the suc- 
cession houses, use the precautious recommended in pages 287, 336, 3S3, and 431. 
Cherry Houses. The fruit on those trees started in January, will now be stoniog. Be very- 
careful that the thermometer range no higher than 00 deg. by day, aud 55 by night, until 
this critical period is over, when the heat may be raised to 70 by day, and 6-5 by night. 
Give abundance of air, and syringe the trees until the fruit begins to ripen, when it must be 
discontinued.
