the degree of pruning differing with character and habit of growth of species. 
Garden vegetables, such as cabbages, tomatos, etc., will endure lower 
temperatures, droughts, etc. if grown more slowly in the forcing bed than is 
customary. — A . N. R. 
Variegation in Chlorophytum. By E. J. Collins (Journ. of Gen. xii. pp. 1-18 ; 
April 1922 ; plates). — Discusses the heredity of variegation in seedlings of Chloro- 
phytum where , according to the parts of the plant producing them, the seedlings 
may be green, white, or variegated, the variegation being often very disorderly, 
but, by a method which the author described, seedlings with such irregular variega- 
tion will often produce quite regular markings on the lateral shoots. — F. J. C. 
Vegetables, Home Storage of. By James H. Beattie (U.S.A. Dep. Agr., 
Bur. PL Ind., Farm. Bull. 879, Aug. 191 7 ; plates). — -Directions for storing the 
surplus vegetables for winter consumption at home. 
The best types of storage shed for the different crops and for different climates 
are described and illustrated, and instructions are given for making a frost- and 
vermin-proof structure in the basement of an ordinary dwelling-house. This 
last, of course, is only suitable to such produce as will not create an unpleasant 
smell through the house. Beans, pears, beets, late cabbages, carrots, celery, 
onions, parsnips, potatos sweet and Irish, pumpkins and squashes, salsify, 
late turnips and apples are the fruits and vegetables treated of. 
Clamps of various kinds and underground or partly underground structures 
are also described. — M. L. H. 
Vines, Planting of Grafted Resistant. By H. E. Laffer (Agr. Gaz. N.S.W. 
vol. xxx. pp. 501-504 ; 5 figs.). — As the Phylloxera resistant vine is more difficult 
to grow than the ordinary vine, careful attention must be given to the prepara- 
tion of the soil some time before planting. It is subsoiled to a depth of 18 
inches and superphosphate or bone-meal is mixed with the soil beneath the roots, 
and well-rotted manure may be added with advantage. Grafted vines are 
planted 12 inches deep, leaving 4 inches above the surface. 
Ungrafted stock is either grafted one year after planting in early spring or 
" Yema " budded in autumn. The young vines are covered with a mound of 
earth, which is removed when the buds appear and the vine is cut back. The 
formation of scion roots must be prevented. — 5. E. W . 
Watering Pot Plants. By A. Petit (Rev. Hort. vol. xcii. p. 68). — Immersing 
flower -pots to half their depth in a vessel of water is advocated in preference 
to the use of the watering can, on the ground that it is more efficient, does not 
disturb the soil, and reduces the loss of nitrates. — S. E. W. 
Weevils of the Genus Sitones injurious to Leguminous Crops in Britain, 
Bionomics of. By Dorothy J. Jackson (Ann. App. Biol. vii. Nos. 2-3, pp. 269- 
298 ; 6 figs., 5 plates). — An account of the life-history of Sitones lineaius together 
with descriptions of the egg, larva, pupa, and adult. 
The experiments were carried out at Wye, Kent, and Ross-shire. 
A key is given to the species of Sitones. Food plants consist of Peas, Beans, 
Lucerne, Medick, Tares, Wild Vetches, and all species of Clover, but the latter 
is not a favourite food plant if the others are obtainable. 
From January to early April the weevils are hibernating amongst long 
grass, stubble etc., and in early spring migrate to Peas and Beans, very soon 
commencing to lay eggs. 
Egg-laying continues until the death of the parent weevil, varying from the 
end of June to the end of August, according to the locality. 
The eggs hatch in about three weeks, and the young larvae become mature 
in about six or seven weeks, and are found feeding on the root nodules of Peas 
and Beans, the pupal stage lasting about three weeks. All the weevils emerge 
before the winter, except occasionally in Scotland, where the pupal stage is 
found in mid-winter. 
There is only one generation in a year. 
Natural enemies include poultry, and, according to Miss Ormerod, starlings. 
Parasites comprise a mite, belonging to the genus Trombidium ; three speci es 
of Braconidae, the commonest being Perilitus nitilus ; and a fungus, Botrytis 
bossiana. — G. F. W. 
White Fly, The Control of the Greenhouse. By LI. Lloyd (Ann. App. Biol. 
ix. April 1922, pp. 1-32 ; 2 plates, 5 figs.). — A very complete survey of this 
well-known pest to tomato growers. 
Aster ochiton vapor ariorum can survive out of doors in S. England during 
mild winters. 
The nymphs depend on living foliage, so much so that they die if the leaf that
