JOUBNAL OF HOBTICULTUBE AND COTTAGE GAEDENEB.

ever shall see in a saddle boiler, no matter how improved, is 

 Chat it will bum anything and everything combustible. Tubular 

 bailers will not, or rather ought not to do so, or their parts be- 

 come so clogged with soot and other products of combustion, 

 as to be practically the reverse of powerful or economical. 



Mr. Cooper concludes by asking, " Shall we, then, continue 

 to erect upright tubular boUers ? " I am glad that he has made 

 the distinction, " upright tubular," for horizontal tubular are 

 those requiring the chimneysweep every morning to clear away 

 the soot and dust. They will never do unless heated by some- 

 thing not emitting smoke. My answer to Mr. Cooper's question 

 is in the affirmative, or " Yes, until a boiler of greater power 

 be invented," and that is not yet done. 



" Shall we return to the good, old, and long-tried saddle ? " 

 Well, no. For detached houses it may do ; for long ranges of 

 houses it is not economical nor efficient. 



Mr. Cooper's la>t querj- 1 will not presume to answer, but 

 I have no doubt the best boiler that will burn any kind of fuel, 

 is the terminal saddle boiler. 



In conclusion, I would point to the old and long-tried flue for 

 economy iu heating small detached houses, or where much 

 capital would have to be invested, if heating had to be effected 

 by hot water ; to a boiler of the saddle pattern for large de- 

 tached houses ; and to the tubular form where coke can be 

 had, and there is much glass. — G. Abbey. 



A LITTLE MORE ABOUT TOBACCO. 



ToDR correspondent, " X." (page 287) seems to infer that 

 when I wrote the article on " The Growth and Manufacture of 

 Tobacco," I ought to have stated how much might be legally 

 grown on Enghsh soil without infringing the law. I must 

 confess that when I penned the above paper I was in ignorance 

 as to the quantity allowed by law to be grown, but fancied it 

 was about a pole. 



I may also state here what I omitted in my last, that I sow 

 my seed about this time (April 2Qrd), because by the time the 

 seedUngs are ready to prick out, the tirst bedding plants will be 

 put out iu the flower garden, so disengaging plenty of small 

 pots. Ab many tobacco plants as will be required are then 

 potted singly, they are started in any warm house where there 

 is room, and hardened off in the cold frames which have been 

 used for bedding plants. Were it not for the want of space, a 

 want felt iu most gardening establishments in the months of 

 April and May, I would sow and put out my plants earher. I 

 do not think that the system adopted by your correspondent, 

 "Ehcg" (page "270), of allowing his plants to remain entire 

 until the approach of frost, is preferable to gathering the lower 

 leaves as they become ripe. When the plants are luxuriant, 

 the lower leaves are liable to decay before the plant is fully de- 

 veloped, they then become useless, and the best and largest 

 leaves are lost. I prefer securing the lower leaves, and di'ying 

 them as they attain maturity, which will be about the middle 

 of September. I have gathered the plants entire, but found it 

 attended with waste. 



I am glad that the subject of growing Tobacco for fumigating- 

 purposes seems to be gaining in interest. I was in conversation 

 the other day with a gaidener who is at the head of one of the 

 first cstabhshments in the kingdom, and he told me that the 

 expense of fumigating for the year was becoming a very serious 

 item, and one which it would be very desirable to obviate. 

 There are very few gardens in which there is not as much 

 space at command as will afford room for a sufficient number 

 of Tobacco plants to serve for the year. I may also add that a 

 sixpenny packet of seed from any respectable seedsman would 

 plant a quarter of an acre of land. 



Since I wrote the communication at page 137, 1 have changed 

 my position, and having to supply the wants of a large estab- 

 lishment from only a limited area of kitchen garden ground, 

 of which every inch has to be cropped with vegetables iu order 

 to meet the incessant tUmand, I purpose growing my Tobacco 

 plants this seasonbetweeu the Asparagus-beds, and as 1 find the 

 ground is very rich, X expect an abundant harvest from them. 



Allow me to state in conclusion, that those who intend to 

 grow Tobacco must be careful iu the drying and storing it 

 away. If it is too dry it wiU not sweat, and then its essential oil, 

 in which its value consists, is lost ; or, if the leaves are too full 

 of moisture they are hable to decay. 



As the pages of " our Journal" are always open for amateurs 

 as well as the professional gardener to relate their practice on 

 all subjects of interest, I trust some of its numerous readers. 



who may be induced to try the experiment of growing their 

 own Tobacco, will ia the autumn, when their plants are 

 gathered and stored away, give us the result of their experience.

MILDEW ON ROSES. 



MrLDEw, or while fungus, is a sad malady when it attacks 

 Roses early in the year, before the new wood is confirmed. If 

 it appears late, it does not so much signify. Anything that ob- 

 structs the lungs must affect the plant. FloTrers of sulphur 

 may be beneficial under glass, but out of doors I never saw 

 any good result from its use. 



Mildew is called " the daughter of di-onght," because long- 

 continued drought thickens the juices of the plant, and makes 

 the young folioles sticky ; fungus then adheres, and in favour- 

 able weather it ia developed. Abundant watering at the root 

 and over the leaves in hot weather, would probably prevent it ; 

 but when it has once obtained a hold of the plant, an abster- 

 gent lotion is the best remedy. Put 2 ozs. of blue vitriol into 

 sufficient hot water to dissolve it, and then put the solution 

 into a stable-bucket of cold water, and pour it with a fine-rosed 

 watering-pot over the leaves. I have known it cure thoroughly 

 a line of Gf-ant des Batailles (much given to mildew, discarded 

 by me now), when the mildew has been rooted deeply into the 

 texture of the leaves. If " Hele!( " (your inquiring corre- 

 spondent) has only a few Fioses, she may sponge it off or rub it 

 off with the finger and thumb on its first appearance. Baronne 

 Hallez is another Kose which is never free from mildew. 



In hot, showery seasons mildew seldom appears on the Bose, 

 nor does it then do any amount of harm. — W. F. R.ii>clyefb.

HoBTicuLTUEAL DissEB. — ^We Understand that Lord H. Gor- 

 don Lennox, M.P., has kindly consented to take the chair at 

 the dinner to be held at St. Martin's Hall (May 24th), during 

 the week of the International Horticultural Exhibition. 



THE MANGO AND MANGOSTEEN. 



I, IS common with many of your readers, have been much 

 interested in the papers by " J. H." on the cultivation of 

 tropical fruits that have from time to time appeared in The 

 JocnxAL OF Hop.Ticci.TUEE. Several of my friends who take a 

 great interest in these matters have gone to considerable ex- 

 pense in the endeavour to rival the doings of "J. H.," and to 

 secure, as he would lead us to expect, such a supply of the 

 fruit of the Mangosteen as would not only furnish their own 

 tables but those of their friends. 



I have lately heard in more than one quarter considerable 

 doubts expressed as to whether " J. H." has really done what 

 he professes. On the one hand, highly skilled cultivators 

 assert that the instructions given by " J. H." cannot possibly 

 succeed, as they are contrary to the conditions under which 

 the tree naturally grows ; others say. Could such a feat in horticul- 

 ture be performed in England without some person having 

 seen it ? Now, I should be glad it "J. H." will, for the satis- 

 faction of your readers, state where he " obtained fruit for 

 three successive years (1859-60-Gl), from one small tree." It 

 6 -'ems strange that such a circumstance should have occurred
