THE FLORAL WORLD AND GARDEN GUIDE. 
if the foliage becomes frozen, water them with cold water before the 
sun gets on them. Walks should he turned and rolled, and grass- 
plots dressed, so as to give an air of neatness and order to the whole 
of the ground. 
GrBEExnotrsE. — If bedding-stock is still in request, cuttings 
should be struck in a brisk heat ; they will bear much more heat 
now than they would a month ago. China roses may be propagated 
in pots by taking off young shoots close to the old wood when four 
inches long, and plunging in a moderate heat. General collections 
should only have a moderate heat, and a strong healthy growth 
should be promoted by giving plenty of air, with a view to putting- 
out the fires for the season. Many specimen-plants will want liberal 
shifts, and all subjects not immediately required in flower, should be 
regularly and frequently stopped to ind uce bushy growth and form 
good heads. Water and liquid manure must be more freely given, 
and vigilant etforts made to keep down the green-fly and thrips. Many 
of the less tender things may be removed to cold pits, to increase 
the room tor other things that want continued protection to make 
fine plants. Young stuff from the propagating-house should be 
potted as fast as rooted, and kept close till started afresh, and then 
be gradually inured to air and light, so as to be strong by the 
middle of May. All tropical plants required for summer blooming 
in the house, should be got on without delay, and a quick growth 
promoted so as to allow them as long a season as possible for bloom- 
ing and ripening their buds for next season. Average temperature 
this month 55 degs. by night, 60 to 65 degs. by day. Where 
desirable, the house may be shut up with sun-heat to render fire 
unnecessary. 
Stove. — Vines in bloom must be kept close, and with a little 
extra fire-heat to prevent injury from damp setting on the berries; 
melons should be encouraged to make quick growth until established, 
and then kept cooler to encourage the production of fruitful wood; 
but do not stop the main shoots till they have extended as far as 
the space allowed them, and then they may be stopped to promote 
the growth of laterals. Pines will want air as often as possible, but 
the atmosphere about them must be kept moist, lied spider will 
now be getting active, and must be kept down. Keep also a good 
look-out for green-fly, especially among young stock. 
KEW BOOKS. 
R. HEMSLEY, late of the Royal Gardens, Kew, has 
published a volume which we commend to every one 
of our readers, as the best of its kind, and a work that 
was greatly needed. It is entitled “ Handbook of 
Hardy Trees, Shrubs, and Herbaceous Plants ” (Long- 
mans), and it forms a portly Svo of nearly 700 pages, handsomely 
printed, and profusely illustrated with excellent wood engravings. 
Mr. Hemsley’s object has been to convey to the reader every item 
of information about every hardy plant worth notice, consistent
