I Such a character, such simple habits of life, a warmly 
attached family, his mother, his sisters, his two daughters, 
j especially the objects of his affection, would have rendered 
| him perfectly happy if his health had not made his work 
difficult, and often almost impossible. Yet such was his 
attachment to his duties, that last spring—when already 
affected by the malady to which he at length succumbed— 
he commenced his lectures and demonstration, which he 
only suspended when his bodily strength completely failed. 
His death leaves an immense void in science and in the 
| establishments with which he was connected. With him is 
extinct the illustrious name of Jussieu, which during three 
generations has been the glory of the Academy and the 
Jardin des Plantes. The heavy burden of a name borne by 
Bernard and Antoine-Laurent de Jussieu, Adrien sustained 
without flinching—lie even gave to the name an additional 
splendour; and it is when the Academy of Sciences had 
called him to the honour of presiding over it, that we have 
lost at the same time a colleague, beloved by all, and the 
president who in a few days hence would have directed our 
deliberations. In addition to the regret which will be felt 
by scientific men of all countries, there is in our case—and 
especially in his who is here the exponent of your sentiments 
1 —the bitter sorrow of the heart. No man was more worthy 
to be loved — no one more devoted and constant in friendship 
—no one who will inspire attachment more deep and lasting, 
and excite more regret among those who know him 
intimately, and who here join with me to bid him a last 
adieu.” 
Artificial Propagation of Salmon. —A meeting of the 
salmon fishing proprietors in the River Tay was held on 
Friday last, at Perth, for the purpose of considering the 
question of the artificial propagation of salmon. The chief 
speaker was Mr. Thomas Ashworth, from Ireland, who 
stated that his brother and he have, at the present time, 
about 20,000 young salmon in ponds, produced by artificial 
means, which are daily fed with suitable food. His brother 
and himself having purchased the Galway salmon fishery, 
in Ireland, they determined to try an experiment there for 
the artificial propagation of salmon. A suitable place hav¬ 
ing been fixed upon at Outerard, operations were commenced 
between the 20th of December and the 1st of January last, 
which was about a month too late, yet boxes were prepared 
in which the spawn of the salmon were deposited. These 
boxes were about 18 inches square, and G feet in length, with 
a zinc grating in the sluice at either end. There were 20 
boxes in all, which were filled with gravel or small stones 
to the depth of six inches. To procure the ova and milt of 
the female and male salmon, the fish were taken by small 
nets on the spawn fords at night, and instantly and without 
injury put into a tub one fourth full of water. The female 
fish was first turned on her back, one man holding the tail, 
and another running his hands down each side from the 
head, and pressing lightly with his thumbs, the ova was 
readily discharged into the tub; a similar course readily 
discharged the milt. About 370 salmon wore treated in the 
above manner, and again returned to the river. Mr. Ash¬ 
worth explained how the ova and milt were mixed in the 
tub, and then taken out of it with a cup and deposited in 
the boxes, when it was covered with additional gravel. 
There were at present about 20,000 young salmon alive, and 
thriving in these ponds, from two inches to three inches in 
length. The fine zinc gratings were used to prevent both 
trout and insects from getting into the ponds, as they were 
very destructive to the salmon-fry. The ponds were about 
20 yards in length, and 12 to 13 yards in breadth, and it was 
intended to keep the young salmon in them for 10 months, 
when they will have grown to about four inches in length, 
j They would then be able to take care of themselves on their 
way to the sea. He stated, also, that it was indispensable 
the young salmon should be fed daily with chopped flesh 
! meat. The current of water running through the boxes 
must be pure and free from mud, and great care was required 
to be taken during the periods of incubation, when the rivers 
were flooded by heavy rains, to divert the muddy water from 
the boxes. It took about 100 days until the spawn gave 
indication of life. The expense of this plan of artificial pro¬ 
pagation he did not estimate to exceed a pound a thousand, 
which was at the rate of one farthing for each salmon. After 
some discussion it was resolved that the experiment should 
be tried in the Tay ; and a committee was appointed to adopt 
the requisite measures .—Edinburgh Courant. 
TO CORRESPONDENTS. 
Rose Cuttings (J. R.) —These will give least trouble under hand¬ 
glasses. They may lie put in now. 
Geranium Cuttings (Ibid).— You made your cuttings too small- 
two or three joints would have been better ; and, if we understand the 
case, the wood was too spongy. See what Mr. Fish said the other week. 
Soils, &c. (Margaret).— Your loam is a light-coloured clayey loam. 
See part of Mr. Fish’s article to-day. Gas-lime must be used with very i 
greatcaution ; we would not advise you to have anything to do with it. 
It would be a capital thing to place at the bottom of walks. Fruit trees j 
will do well in the ground mentioned. The deep trenching and the new 
soil gave strength to the Fuchsias. Cut down'after frost ; they will, pro¬ 
bably, do better next year. The Tropceolum bulb had not been old 
enough ; let it alone until the foliage is quite yellow ; then leave it dry 
in the pot, or take it out, and place in dry earth, free front frost, and 
repot next spring, as soon as the growth commences. When growing, 
and after May, you must give it air in your window. The Lemon Ver¬ 
bena (Aloysia citrindora) is easily propagated from cuttings in spring, 
and as easily kept in a window. We saw two huge bushes yesterday, at 
the side of a gardener’s door. They are cut down every autumn, like a 
Fuchsia, and protected with ashes and a mat during winter. 
Nigiit-scf.nted Stock (Ibid). —Take cuttings also in spring, so that 
young plants are established befoie winter. Nothing will make the plant 
look beautiful; its sceut, at night, from its dull-looking flowers is the 
great charm. It must have little water in winter, and the cuttings in 
spring should not have a damp place, unless there is artificial dry heat to 
drive it olf. 
Tank for heating Greenhouse (J. R. C ..).—This house is 20 feet 
long, 12 feet wide, and 9 feet high at back, and 5 feet in front. The 
position, of course, must be beneath your stage ; but your plan will only 
be effectual for plunging pots above the tank, to secure bottom-heat, by 
having all the plants on the stage supplied with saucers. Even then, of 
course, you could have no bottom-beat of any consequence, unless in very 
cold weather. You may make the tank as long and as wide as convenient— 
say 14 feet by 6 feet, and four inches deep. Well-managed, you would find 
it useful; the plunging material above the tank being used chiefly for 
propagating purposes. 
Rose-buds not started, but alive (Flora). —Do not stop the 
shoots now, that might start them into growth, to be killed by the frost. 
Cut back when they have grown a little next spring. It is usual to pinch 
the point of a shoot that has a bud inserted at its base, to cut it back 
farther when it is growing, but not to cut to the bud until it has gained 
some strength. This on principle, but frequently vve have bad a shoot 
broken off near a strong bud, and it immediately went off at railroad 
pace, with all the sap that went to the shoot appropriated. In your 
case, we would cut back nearly to the inserted hud when growth was 
proceeding in spring. 
Banana — Thinning Fruit (Blythina). —We should think there would 
be no danger, if the plant was rather dry, but we have not had much 
practice. 
Cherry-trees and Pear-trees (J. B. B .).—These bloom freely, 
but do not fruit, though Apple-trees do well near them. Are you near 
the smoke of a town ? that will account for it, as the soot clogs the parts 
of fructification. Does your grass lawn slope at all; or does it allow 
enough of water to get to the roots while the trees are in bloom ? They 
seem to be dry enough, and near the surface enough, when they bloom 
so freely. If you think none of these are the reason, brush the blossoms 
next season with a feather, or a camel’s-hair brush. 
Vineries, &c. (Ibid). — Better “let well alone.” Either in a pit, 
or on the floor, in such a house, with Vines up the rafters merely, good 
gardeners will grow Peaches, Vines, Oranges, Cucumbers, and Melons, 
in pots or boxes, provided there is heat for the two latter ; but recollect, 
that attention to Peaches, Figs, &c., will interfere with what the Vine 
requires. We know many instances of gardeners obtaining a wonderful 
amount out of such houses, but then quality has in some, if not all, the 
things, to be sacriticed to quantity. For Cucumbers, a little bottom-heat 
would be desirable. Rhubarb can be grown anywhere in winter and 
spring, where you can command a temperature of from 50° to 60°. We 
have grown that and Sea-hale on the bottom of an early Vinery, keeping 
the Kale from the light. Of course, the well-matured roots were brought 
from the open air, and taken out when done with. You will do no good 
with permanent plants in such a house unless they have unobstructed f 
light. 
Pillar Roses — fifteen or sixteen fef.t high (M. S.). —See the 
description, and consult the section of that kind of Roses in a nursery- j 
man’s catalogue. You cannot expect such things in a day. The ground 
must be deeply trenched; consist of good mellow loam, well drained, 
with abundance of dung and manure waterings ; and proceed just as if 
you wished a symetrical bush a yard high, and eighteen inches in 
diameter. The pruning must regulate the shape ; and, provided soil and 
manurings are suitable, time will produce the .lesired result. Of course, 
you are aware that when one shoot is selected for a leader, and other 
subordinates to stand round it, the lower shoots must be trained nearly 
horizontally, to give the greatest width at the base line. 
Geraniums for Box outside the Window (Ibid).—Compactum 
is rather strong growing. We would prefer Tom Thumb, or Improved 
Frogmore. 
Fuchsias rooted in Spring (Ibid). —Keep them in the pots in which 
they are ; if in the ground, protect them there, or lift and pack them in 
pots and boxes when the leaves fall, giving them separate pots as they 
begin to grow. Fuchsias, grown as standards until they become large, 
will not want large shifts, as the heads will be smaller than plants of the 
same height, clothed like a pyramid, from top to bottom. Spring-rooted 
cuttings is a rather indefinite expression. We have such Fuchsias now of
