tans, (see Register, page 420;) the Smooth Dor Beetle, Geotrupes Ice'vis; the Two-spotted 
and the Tortoise-shell Lady.birds, Coccinellu, bipunctuta and d'lspar may now be met with. 
BIRDS.—The latest of the summer migratory birds arrive in this month, and the last of those 
of winter have left us. Those winch arrived last month are now busied in the construction of 
their nests, or the care of tlieir eggs or young. The nests of the Lesser V/hite-throat may be 
found generally in the White Rose, (Rosa arvensis ,) of the Winchat, in hollows excavated 
in the ground; and of the Sedge Warbler, in the willows, in the water, or in a bush on the 
bank, near to where the male sits singing his varied and imitative song night and day, ever 
watchful to apprize his mate of any approaching danger. 
In some of those calm, mild, beautiful moonlight nights, which frequently occur in this month, 
the Cuckoo may be heard singing for 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 Crex, (Ortygdmetra Crex,) is the earliest visitor of the month, 
generally arriving in the first week. The Night-jar, Caprimulgus europa'us, (Nyctichelidou 
europae'us,) may be found in the twilight, on heaths and among fern, pursuing on the wing 
such beetles and other insects as frequent those places. The Lesser Butchcr-bird, Ldnius 
coUurio, 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 may easily be known. The Greater Pettychaps, or Fauvette, Sylvia 
hortsnsis, and the Wood Wren, Sylvia sylvicdla, (Sylvia sibilatri.x,) arrive in the beginning of 
the month. The Spotted Fly-catcher, Musciedpa grisola, and the Pied Flycatcher, M. atrica- 
pilla, which may in general be considered the last of the summer birds, arrive about the middle 
or latter end of the month,

MONTHLY HORTICULTURAL CALENDAR, 
FOR MAY, 
The exceeding fine weather we experienced early in April seemed 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 plentiful fruit year. Wall trees will 
still require protection. Sowing and j)lanting 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 will require their fore-right shoots rubbing otF, and the 
side ones properly 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 plants put 
in. Look well to the Cucumber and Melon frames; and give green-house plants air, night and 
day when the weather is fine, which will much prolong the flowering season. 
FRUIT DEPARTMENT. 
Protect W'all 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 precautions recommended in pages 287, 336, 383, and 43i. 
Cherry Houses. The fruit on those trees started in January, will now be stoning. Be very 
careful that the thermometer range no higher than 60 deg. by day, and 55 by night, until 
this critical period is over, when the heat may be raised to 70 by day, aud 65 by night. 
Give abundance of air, and syringe the trees until the fruit begins to ripen, when it must be 
discontinued.
