clothing is stored, the fragrance being a deterrent to insects. 
Furniture is sometimes manufactured from the wood, whilst it 
can also be used for panelling. Lack of a regular supply of the 
timber is probably the reason for the poor price realised, and with 
this and other woods that only appear upon the market as isolated 
examples the owner would often be well advised to have them 
cut up and worked for private purposes.—w.D. 
Poplars for Farm Land.— Although badly placed trees interfere 
a good deal with the proper use of agricultural land there are 
positions on most large farms where trees may be grown with 
advantage to the farmer either in the provision of shelter, shade 
for stock, or the cropping of land unsuitable for agriculture. 
In some places such land may be narrow copses or spinneys two 
or three acres in extent, in others there may only be space for a 
few trees, whilst elsewhere isolated trees may be needed along 
boundaries or water-courses. Wherever trees are needed, how- 
ever, a species suitable for the position should be chosen and one 
that may be calculated to bring in revenue at some future date. 
Too often the trees planted in such places are mixed lots left in 
nurseries after the end of the planting season, whereas they 
should be as carefully chosen as trees for planting over extensive 
areas. Where land is moist but not waterlogged, poplars are 
satisfactory trees to plant. They are hardy, grow rapidly, and 
under ordinary conditions bring in a satisfactory return at the 
end of 50 years. They may even be induced to grow on water- 
logged land by opening deep drains and planting cuttings or young 
trees on mounds two to three feet above the ordinary level. 
Moreover they are peculiarly suitable for small groups, narrow 
plantations and isolated trees near water, as they need to develop 
good heads of branches to insure satisfactory trunk increment. 
It is better to plant one kind than a mixture, and either one of 
the following may be chosen: Populus serotina, P. Eugenii, 
P. trichocarpa, P. robusta. P. Eugenii and P. robusta form much 
narrower heads than the other two, therefore they shade less of 
the surrounding land and are less liable to wind injury than the 
others. Cuttings one to three feet long may be inserted in the 
places the trees are to occupy, or cuttings a foot long may be 
raised in a garden and the young trees be planted out at the end 
of the first or second year. They must be protected from stock 
and vermin for a few years, the only other attention needed 
being the occasional removal of lower branches and keeping the 
trunks to a single leader.—w.p. 
_ Index Kewensis——The task of compiling the quinquennial 
supplements of this work is steadily growing every year owing to 
the increasing amount of literature that has to be examined for 
the extraction of names. To add to the difficulties that have 
been encountered in recording synonymy generally, a practice 
has grown up of authors indicating after the specific name only
