which are necessary for it, in the same way that the nataral 

 bud would draw them immediately from the earth. It may be 

 that in the passage which these juices are forced to make 

 throughout the roots and the stems of the subject, they reach 

 the fibres of the bud better elaborated than they would have 

 been if drawn directly from the soil. But whatever may bo 

 the state in which they may be found at their entrance into 

 the fibres of the bud, they wiJl always be modified by the organs 

 of that individual, as those would be if drawn from the air, or 

 those drawn from the earth, if they were placed in it without 

 interception of another plant. Experience has confirmed 

 these principles, and the world is convinced that a graft does 

 nothing more than to perpetuate species or varieties without 

 altering them. 



I have made in the course of fifteen years a series of obser- 

 vations upon this subject, keeping always the mother plant 

 side by side with the grafted one. I have grafted Oranges 

 npon Lemons, Lemons upon Oranges ; I have grafted the 

 Bweet Orange upon the Bigaradier, and reciprocally I have 

 grafted Apricots upon the Plum, Peaches upon Apricots, and 

 I have not been able to see the slightest difference between 

 the fruits furnished by the graft and those of the plant from 

 whence it was taken. I have never obtained any otlier result 

 from these experiments, except simply to preserve rare varieties 

 which I was not able to propagate from seed, from the double 

 reason that they very rarely had seed, and if they had they so 

 frequently produced degenerate varieties. 



NAMES OF PLANTS— ENGLISH versus LATIN. 



My friend asks, " What is this pretty flower?" " Gelasine 

 azurea." "What a long name!" "I cannot shorten it." 

 " But why have a Latin name ? Better call it Blue Smiler in 

 plain English." '■ Then you like such names as Shamrock, 

 Blue Bells, Eglantine, and Culverkeys ? " " Certainly, every- 

 one can understand them." " You can recognise the plants ? " 

 " Easily." " Well, lean show you in print endless discussions 

 as to what they are. On the other hand, I defy you to pro- 

 duce two persons who disagree as to what plant is meant by 

 Eucharis amazonica. Now, look at page 32 of ' our Journal.' 

 Would you like some of the plants described in the American 

 Christian Weekly ? The Night-blooming Jasmine must be 

 very desirable, but what European nurserymaa could under- 

 stand the name? Looking down Don's long list, he would at 

 last hit upon Jasminum noctiflorum ; but as this is a native of 

 Sierra Leone, it is not likely to be the right plant. Paradoxical 

 as it may seem, Latin is in such matters more inteUigible even 

 to an Englishman than English." — G. S. 



CERCIS SILIQUASTRUM. 



While visiting the Botanic Gardens at Leyden, in Holland, 

 at the beginning of May, I was very much delighted with the 

 beauty of this curious yet beautiful plant. In the above gar- 

 dens there are three grand specimens, one against a west wall 

 and two others against a south wall. The circumference of 

 one of these, at 6 feet from the ground, is about 12 inches, 

 the stem reaching to the top of the wall, which is from 15 to 

 18 feet in height. At the top of this wall the branches extend 

 in a horizontal position to the length of 45 or 48 feet. 



During my visit the whole of these trees were covered with 

 their beautiful blooms. The flowers, which are of a bright 

 rosy pink, are produced in bunches from the old wood, with- 

 out any foliage, which has a very curious yet beautiful ap- 

 pearance. — A. M. C. JoNOEiNDT CoNixcK, Tottenham Nurseries, 

 Dedemsvaart, near Zioolle, Netherlands. 



A NEW MODE OF GLAZING. 



In answer to Mr. Eobson, the practical value of nail-bag 

 strand is its being a soft medium for utilising and retaining 

 white lead (which will dry and harden), and su rendering the 

 latter effective for the object of fastening the glass and keeping- 

 out water. Cotton or Flax fibre might do equally well ; but I 

 think the white lead would render the other just as durable, 

 and it is of no cost, and ready made. 



I quite assent to Mr. Eobson'a objection to a strip of wood 

 having to be removed to replace broken glass, but I do not 

 consider this would be necessary ; and if a groove were cut out 

 of the solid bar for the glass, the caulking could be taken out, 

 if required to replace glass, where wanted. There would be 

 no chipping of the wood as in the case of putty. I do not 



consider that this caulking would swell at all ; the oil in the 

 white lead should, and would, effectually resist moisture. I 

 have not tried this for glazing. The idea suggested itself on 

 reading the article in your Journal of April 'jth, page 287. 

 I have, however, found the caulking answer perfectly and 

 permanently in stopping leakage in a lead gutter, and cracks 

 in walls and joints in coping, and all I can say further to 

 Mr. Eobson is, " Try it."— V. 



HEATING. 

 We have received a very long communication on this sub- 

 ject, but can only insert the following: — A correspondent 

 expressed an opinion that a combination of something like the 

 " Arnott," plus boiler and piping, would be " an effectual and 

 economical heating medium." A combination somewhat ana- 

 logous has just been brought out by Dennis & Co., of Chelms- 

 ford, and I annex a section of it (fg. 22). Mechanically it is 



an independent boiler surrounded by an air-casing. Again, 

 part only of the atmospheric air necessary to sustain com- 

 bustion is allowed to enter the fire below the bars ; the re- 

 mainder traverses the casing in the direction of the arrows, 

 and ia drawn (by this time partially heated), into the fire at 

 the top of the burning fuel ; so that in this boiler we have a 

 parallel arrangement to what is known in the steam engine 

 as the jacketed-cyUnder and feed-water heater. — G. Fawkes. 



DAMP WALLS. 



If salt is the cause, I know nothing effectual. Sea sand 

 used in mortar, hair from salted hides, hanging flitches of salt 

 bacon against walls, are common sources of the evil. The salt 

 gets into the bricks and it becomes a chronic disease. Mr. 

 itobson says battening inside " cannot be done " in his case ; 

 but will this avail him ? — strips of wood 2 inches by half an 

 inch nailed horizontally or vertically on the interior of the wall, 

 and on these half-inch deal boards. These may be formed into 

 panels, according to taste and space, by nailing on 4-inch-by- 

 half-an-inch stiles, moulded on the edges. The boards should 

 be dry and the joints rebated, and, of course, planed on one 

 side. This, stained and varnished, makes a comparatively 

 cheap and permanent lining to a room, and is very effective. 

 If Mr. Eobson liked to be at the trouble of removing the plaster, 

 this boarding would occupy little if any more space.— V. 



YouB correspondents who suffer from damp walls should try 

 the petrifying liquor of the Silicate Paint Company, Fenwick 

 Street, Liverpool. I have not tried it for an outside wall, but 

 I have tried it on the inside wall of a cellar made of porous red
