The Weekly Florists' Review* 



1503 



vou have soaie mongrel variety tlmt 

 proves unsuitable for forcing. I would 

 suggest that you try some of this seed 

 outdoors and see what it comes to. Also 

 luoeure seed from some other source, 

 'vJiieh it would be well to prove before 

 cloi)ending on it for your winter supply.

CYANIDE BURNED LETTUCE. 



1 have been using hydrocyanic acid 

 .Tjis by the formula you gave a couple of 

 wooks ago. I used eleven crocks in three 

 houses 29x244. Two of these houses had 

 ];nge lettuce nearly fit for market, the 

 other one small plants nearly covering 

 Ihc o round. The following day I noticed 

 (luite an amount burnt on top. I had 

 the houses and crops dry. Did I use too 

 iiuich ! I notice it did not kill all the 

 upliis on the large lettuce but nearly all 

 on the small lettuce. Will you kindly 

 set mo right on this? S. J, P. 



I am sorry I can't help you out in 

 jliis, as in all my experience with gas I 

 never have had a sign of burning on let- 

 tuce when using the gas strong enough 

 to destroy the aphis. The fact that you 

 did not kill all tlie aphis proves that 

 your gas was not too strong. It may 

 liave been caused from some impurity in 

 tlie chemicals used.

Greenhouse Beating. 



FLUE TO HOT WATER. 



I have a house 13x34 feet, walls four 

 feet high, ridge nine feet. I have been 

 heating it by means of a flue, but don't 

 like it. Will a Winchester heater rated 

 at 225 feet be large enough to keep 55 

 degrees in zero Aveather? Will a 2-inch 

 flow and five 1^4 -inch returns be enough 

 radiation? How large a heater will be 

 needed for a house 34x60, posts four 

 feet, ridge nine feet, bars eight feet ? 



E. U. P. 



The boiler in question should be am- 

 ply large to supply heat for the house 

 you mention, 13x34 feet. To heat this 

 house to 55 degrees in zero weather will 

 require about 175 square feet of radia- 

 tion, which can be supplied by the 2-ineh 

 riser and ten 1 14 -inch returns. Only 

 five returns would give the plants the 

 diills on cold nights. For the house 14x 

 no feet it will be necessary to provide 

 ton 114 -inch returns and a 2-inch sup- 

 ply. If you contemplate adding the lat- 

 ter house, and it is to be near the other 

 house, it will be economy to install a 

 boiler large enough for both houses. A 

 heater rated at 750 to 1,000 square feet 

 of radiation will be ample for both 

 houses. L. C. C. 



BOILER AND PIPING. 



I am building four greenhouses. Three 

 are each 19x100, side wall five feet; the 

 other is 9x100. All four are connected. 

 I intend running the main flow across 

 the end of the four houses and the re- 

 turn across the other end of the houses. 

 Will a 21^-inch flow and return be large 

 enough? Will six 1-inch pipes in each 

 house be suflScient to keep 50 degrees in 

 zero weather? All the benches are solid 

 and one pipe will run on each side of 

 each bed. The small house Avill have 

 only four pipes. Is a steam boiler of 



House of Gov. Herrick Violet at H. R. Carlton's, Willoughby, O, 



twenty-five horse-power large enough to 

 heat this amount of glass ? H. L. L, 



Each of the houses 19x100 feet, if to 

 bo heated Avitli steam by 1-inch pipes, 

 sliould have thirteen pipes the length 

 of the house, and the house nine feet 

 wide should bo provided with seven 

 pipes. Tlie main flow pipe from the 

 boiler should be a 4-inch ; a 2-ineh re- 

 turn, however, will be ample. If hot 

 water is iised, the pipes should be in- 

 creased to 2-inch ; 1-inch pipe is too 

 small for hot water in 100-foot runs. 

 The twenty-five horse-power boiler, if 

 of the return tube type, will be ample 

 for the work. L. C. €. 



GOVERNOR HERRICK VIOLET. 



One of the accompanying illustrations 

 is the portrait of H. R. Carlton, Wil- 

 loughbv, O., and the other is a reproduc- 

 tion from a photograph taken in one of 

 Ills liousos of Governor Herrick violets. 

 This variety is the newest single. It 

 originated with Mr. Carlton six years 

 ago and was named for the then gov- 

 ernor of Ohio. Mr. Carlton early recog- 

 nized that it was one of the freest bloom- 

 ing violets he had ever grown, plants 

 producing over -200 blooms in a season. 

 He has picked steadily from this variety 

 from October 1 to May 15, and since he 

 has been growing it in quantity the 

 blooms have been shipped to the Cleve- 

 land Cut Flower Co., Cleveland, where 

 they have sold exceedingly well. The 

 flower is deep purple, very large, borne 

 on strong stems six to nine inches in 

 length. The plants are vigorous and 

 have never been affected by disease. 



This season Mr. r'nrlton has three houses 

 of the variety. One is 25x160, one 20x 

 130 and one 11x130. He has six houses 

 in all, about 25,000 square feet of glass. 

 In connection with his greenhouses he 

 has a flower and seed store and does a 

 very large retail trade. 



With the 

 Advertising Man 



Advertising is salesmansliip on paper. 

 If you let tills fact sink in deep, judg- 

 ing your advertising from the stand- 

 point of the prospective purchaser, you 

 will find it a great lielp toward success. 



My last subject was handbills, and 

 this time I want to talk about circular 

 or form letters. 



In the first place, your letters must 

 talk to your prospective customer just 

 as you would if face to face. Second, 

 they must be short and right to the 

 point — no words wasted— and bo written 

 in a happy strain, for under no circum- 

 stances is it permissible to run down 

 anyone else. 



You will find that a series of five or 

 six letters, well written, on good sta- 

 tionery, using a plain white envelope 

 with a 2-cent stamp on every one, if 

 mailed to a selected list of people you 

 wish to come in close contact with, wlU 

 bring you surprising results. 



If you will give me an idea of how 

 many people you can reach, stating 

 whether you have a store, or greenhouse, 

 what class of trade you desire to get 

 after, and such other information as 

 would be of assistance, I will send you 

 a series of four or five letters tksit I 

 know will pull business, for they have 

 done it for others in your line.

Aurora, III. — Plans are being con- 

 sidered for a number of improvements 

 to be made soon at the plant of the 

 Aurora Greenhouse Co. A new green- 

 house may be erected.
