The Weekly Horists' Review. 





The Roses at the Boston Trade Show. 



A. Patten & Co. had fine vases of Gene- 

 vieve, white, and Hattie Starrett, varie- 

 gated yellow. H. A, Jahn had a variety 

 of seedlings, some very good. J. D. 

 Cockcroft had Georgia in good shape. 

 Among unnamed seedlings, a light pink 

 from Leonard Cousins looked well, also 

 crimson from L. E. Small and Samuel 

 Kinder & Son, N. D, Pierce had a prom- 

 ising yellow. F. E. Pierson had some 

 fine things, several Winsor sports being 

 specially taking. Henry Schrade had 

 his yellow, Kanarienbird, and Wanoka 

 Greenhouses had Apple Blossom. 



Thomas Pegler, for Buxton & AUard, 

 showed the popular economy bracket. 

 Daniel Iliffe had a section of a green- 

 house to show how his new ventilating 

 apparatus worked, also other greenhouse 

 sundries.

The attendance was very large, the 

 halls being crowded during the whole 

 time the exhibition was open, some thou- 

 sands visiting it on the second day.

PRESERVING GREENHOUSE WOOD 



I should like to know if experience 

 has proved that pine tar-applied to green- 

 nouse benches is injurious to plants. 

 Pine tar is a good wood preserver, and 

 as it is a vegetable matter it might not 

 be detrimental. I am paying $35 per 



thousand feet for rough pine fencing and 

 am consequently interested in wood pre- 

 servatives. • J. A. W. 



If J. A. W. is using rough pine fenc- 

 ing for greenhouse benches, and paying 

 the price he mentions, he should sit down 

 at once and write to some of the adver- 

 tisers of pecky cypress who offer this 

 bench material in the Eeview. But it 

 will be a matter of general interest to 

 hear from any reader who has used pine 

 tar on the woodwork of his greenhouse. 



Carbolineum. 



In the Keview of February 11 A. J. 

 Pennock asks for information regarding 

 the value of S. P. F. Carbolineum for 

 preserving wooden benches in green- 

 houses. I used Carbolineum on the posts 

 and framework of my benches, and to 

 the fumes from the Carbolineum I at- 

 tribute the fact that a bench of smilax 

 and one of asparagus were killed. I 

 think my bedding plants in the same 

 house are also beginning to show the ef- 

 fects of the fumes. E. J. Hxill. 



Experiments by the National Government. 



The United States Forest Service made 

 some investigations on the preservation 

 of greenhouse timbers during the last 

 year, and has treated timbers experiment- 

 ally with various wood preservatives, but 

 of course no results could yet be ob- 

 tained on the relative efficiency of the 

 diflferent preservatives used. 



An investigation of the open tank 

 prouess of treating was tried in these 

 tests and found feasible. This process, 

 which has been used successfully with 

 fence posts, poles and other timbers, 

 consists ordinarily of a thorough heating 

 of the timber in a hot preservative, fol- 

 lowed by an immersion in a cold pre- 

 servative. The modification consists in 

 using oven heating in place of heating in 

 the preservative. It was found that by 

 two to four hours' heating and two hours 

 in cold solution, almost complete pene- 

 tration of the sap pine boards could be 

 obtained. The advantage of oven heat- 

 ing is that it makes possible the use of 

 the principle of the hot and cold bath 

 with corrosive salts, like mercuric chlo- 

 ride and copper sulphate. 



Creosote has long been the standard 

 preservative, both in this country and 

 abroad, for timbers which come in con- 

 tact with mucJ* n'oisture. In compara- 



tively dry situations antiseptic salts may 

 be used to advantage. If appearance is 

 a prime consideration, creosote should 

 not be used, as wood so treated will not 

 take paint. 



The following is an estimated cost of 

 treating lumber on a small scale:

The Forest Service has not made any 

 experiments with crude petroleum for 

 the treatment of greenhouste timbers, 

 which has been used to a limited extent 

 in treating fence posts and poles. I am 

 informed that a railway company oper- 

 ating in the southwest is obtaining good 

 results from the use of crude petroleum 

 for treating ties. 



The Forest Service has issued a num- 

 ber of circulars describing the open tank 

 process of treating in its application to 

 posts and other timbers. Any of these 

 may be obtained on request.

TEMPERATURE FOR ASPARAGUS. 



Would carnation temperature be all 

 right for asparagus ferns? D. S. 



Asparagus will grow in carnation tem- 

 perature, but will grow much more rap- 

 idly, and of as good quality, in a tem- 

 perature 10 degrees higher. A. F. J. B. 



Albany, N. Y. — At the annual banquet 

 of the Albany Florists' Club, February 

 18, there were present President Fred 

 Goldring, John A. Howe, Jr., Fred A. 

 Danker, James H. Snyder, Rhinebeck; 

 John C. McAllister, and Patrick C. 

 Hyde. 



Poughkeepsie, N. Y. — Friday morn- 

 ing, February 26, about half-past five, 

 the hot water boiler at Eelyea's green- 

 houses, on Orchard place, burst beyond 

 repair. Owing to the mild weather, not 

 much damage resulted. A new boiler was 

 installed in time to have fire up in it by 

 four o'clock the same day.
