- Eosemaky Russet Apple.—W e have received from Mr 
Turner of Slough very fine samples of this excellent dessert Apple> 
which he considers not only as one of the best in quality at this season 
of the year, but one of the most profitable to grow. In a plantation 
which includes many varieties in a bearing state this is regarded as the 
most productive, the trees being every year almost overladen with fruits. 
Those sent are above medium size, 3^ inches wide at the base and 
3 inches high, narrowing acutely to the apex. They are more or less 
covered with russety veins, and flushed with red on the side next the 
sun. The flavour is sprightly and excellent, and the variety would seem 
to have claims to more extended cultivation. 
- Blanching Endive in Heat.—I have found it a good plan 
to take up and pot a few plants of Endive at intervals for meeting the 
demand, removing all decayed leaves, also the soil from the collars of the 
plants, which prevent any more decaying, giving water freely to 
prevent flagging. After allowing the water to drain oS I tie a sheet of 
brown or white paper round the pot and plant, tying paper round the 
top for obstructing light. In this way the Broad-leaved Batavian can 
be blanched in about four or five days by placing the plants in a tem¬ 
perature of G0° to 6.5°. The curled or moss varieties will not endure so 
much heat. I have had plants of Endive perfect models of ivory white, 
fully compensating for the little trouble in producing them.—G. W. W. 
- The Essex Field Club. —The tenth annual general meeting 
will be held Saturday, February 1st, 1890, at 7 P.M., in the Public Hall, 
Loughton, Essex. The report of the Council for the year 1889 and the 
Treasurer’s statement of accounts will be read and submitted to the 
meeting. The election of new members of the Council and Officers for 
1890 will also take place. The annual presidential address will be 
delivered as follows :—The Migration of Birds, by E. A. Fitch, F.L.S., 
F.E.S. An ordinary meeting (the 111th) will also be held for the 
proposal and election of new members. Exhibitions of objects of 
natural history, geology, or microscopy, are solicited for the above meet¬ 
ing. Intending exhibitors are requested to communicate with the Hon. 
Secretaries, Messrs. William Cole and G. B. Cole. 
- The Great International Horticultural Exhibition 
at Berlin will be held from the 25th of April till the 5th of May, and we 
hear that the preparations have advanced in a most satisfactory manner. 
The Emperor, on the suggestion of the President of the E.xhibition, Hr. 
Lucius von Ballhausen, has appointed the large gold State medal for 
the most meritorious horticultural production at the Exhibition, and 
eighty other medals will be granted. All the German Governmental 
railways, as well as several private companies, have promised to return 
unsold objects free. The Farmers’ Club of Berlin have also established a 
prize of 100 marks (£5). Every means will be employed to arrange 
the Exhibition in the most effective manner. Programmes may be 
obtained from the office of the General Secretary, Invalidenstrasse 42, 
Berlin, N. Germany. Entries close on the 1st of March. 
- A Few More Words from America.—T hanks for your 
insertion of a few words respecting the doings of our old horticultural 
friend, Mr. Laurence in his American home. In a further letter just 
received, in which he encloses Primula blooms, he says;—“You will 
see (a copy of the American Florut is referred to) that Roses and Car¬ 
nations head the list for cut flowers, and the quantities grown are to a 
Britisher enormous, and the way Roses are mailed (i.e., posted) is some¬ 
thing also to wonder at. My friend Reid of Cbambersburg has house 
after house, each containing 18,000 to 20,000 in 24 -inch pots, struck in 
summer, and retailing at 1 dol. per dozen ; very few H.P.’s. Winter 
has not yet come, and Christmas Day was like a fine Easter Sunday in 
England, and the grass is still green. It is stated by old sailors that 
the Gulf Stream is several hundred miles nearer the Atlantic coast. If 
really so, that may account for the phenomenal weather we have liad 
the past two years, but we do not like it. It is too English-like for 
us.”—W. D. 
- The late Mr. John Henderson.—I n your last issue you 
gave a notice of the death of this eminent horticulturist, as remarked in 
the Avteriean Florut. Mr. John Henderson was a son of the late Mr. 
E. G. Henderson, of the Wellington Road Nurseries, and was, previous 
to his going to America, a partner with his brother, Mr. Arthur Hender¬ 
son, and his uncle, Mr. John A. Henderson, in the Pine Apple Place 
Nurserie.=, the firm being that of J. A. Henderson & Co. At that time 
the Pine Apple Nurseries, Maida Vale, had a world-wide reputation, and 
one of your earliest contributors on the establishment of the Journal, 
the late Mr. Thomas 4ppleby, was for years the Orchid grower, and an 
esteemed colleague of mine. I well remember the dissolution of partner¬ 
ship by the retirement of Mr. John Henderson, as it fell to my lot to 
assist materially in making up the partnership accounts. The late Mr. 
John A. Henderson was a warm supporter of the Gardeners’ Royal 
Benevolent Institution from its formation to the time of his death. Mr. 
Andrew Henderson, another brother of Mr. John, and Mr. Arthur Hen¬ 
derson, were in partnership with their father, Mr. E. G. Henderson, at 
the Wellington Road Nurseries for years, and he is now connected with 
the old Pifte Apple Place Nurseries, and I be’ieve his brother, Mr. Arthur 
Henderson, is still living.—W. D. 
- Spraying Fruit Trees with Arsenites. —At the meeting 
of the American Association for the Advancement of Science, held at 
Toronto, this subject was taken up by Professor A. J. Cook. He said : 
Again, as our wild fruits are more cleared away we only need to spray 
our Apples once to destroy the codling moth, and can treat the Plum 
trees three or four times with Paris green or carbolated lime in case we 
have only occasional showers. For the Apples we can use London 
purple, 1 lb. to 200 gallons of water. For the Plums against the 
carculio we must use Paris green, 1 lb. to 200 or 300 gallons of 
water. Respecting the injury done the foliage by the use of 
arsenites, he said : London purple is more injurious to the foliage than 
is Paris green, and white arsenic—arsenious acid—is more harmful than 
is either London purple or Paris green. This is doubtless owing to the 
soluble arsenic which is quite abundant in London purple, and almost 
absent in Paris green. London purple may be used on Apple, Plum, 
Cherry, Pear, and most ornamental trees, but on these should never be 
stronger than 1 lb. to 200 gallons of water. If the application is 
to be repeated, as it must be for the curculio, to prove effective, or if it 
is to be used in June or July, Paris green should be used in the same 
proportion as above, or else we should only use 1 lb. of London 
purple to 300 gallons of water. I now think that this necessity is more 
due to time of application than to the fact of increased quantity of the 
poison. If the arsenites are to be used on the Peach to defend against 
the curculio Paris green only should be used, and that not stronger than 
1 lb. to 300 gallons of water. The injury done to the foliage is 
never immediately apparent. It usually shows somewhat the second 
day, but the full injury is frequently not manifest till the fifth day, and 
often not till the tenth. He likewise demonstrated that there is no 
danger of cattle being poisoned by eating the grass under the sprayed 
trees. Professor Clarence M. Weed of Columbus, 0., read a paper on 
a similar su’oject—remedies for the Plum curculio. An experiment 
with Cherries was made, spraying half an orchard with London purple, 
1 lbs. to 160 gallons of water. He then picked Cherries from sprayed 
trees and unsprayed trees, and in every case there were more wormy 
Cherries on the unsprayed than on the sprayed trees. The average was 
—unsprayed trees, eight per cent, of wormy Cherries ; sprayed trees, 
three per cent of wormy Cherries. The benefit from the spraying 
hence was 75 6-10 per cent. Experiments were also made with Plums 
when an orchard of Plums was sprayed with London purple several 
times. An enormous crop was the consequence, although two untreated 
trees had their entire yield destroyed. He concluded that very much of 
the damage done by the curculio could be safely and cheaply prevented 
by the use of arsenites. Professor Saunders of Ottawa expressed his 
opinion that Paris green was a better arsenite to use than London 
purple. 
DESTROYING THE EUCHARIS MITE. 
I HAVE observed of late that several of your correspondents have 
claimed credit for good cultivation of the Bucharis. 1 have no wish to 
speak lightly of the merits of any successful cultivator, especially if 
he or she be an amateur or a beginner ; but given conditions which are 
at all favourable I should hardly consider the Eucharis the most diffi¬ 
cult plant in the world to grow. Indeed, when we remember how it is 
baked in one place, stewed in another, and poisoned in a third, accord¬ 
ing to the whims of the different cultivators, and that it not only 
survives, but does fairly well in each case, one would be inclined to 
consider it a remarkably easy plant to cultivate. In practice many 
others beside myself have found it so. But having succeeded ourselves 
shall we call our brother gardeners unskilful who have failed to do the 
same ? Because we have never been troubled with insects at the roots 
of our plants shall we say there is no such thing as Eucharis mite ? 
I might just as well say there is no such thing as influenza because I 
do not happen to have that disease myself. 
I have grown Eucharises uniler favourable conditions and succeeded. 
I have attempted to grow them under other conditions and have miser-
