STOCK, BEAUTY OF NICE. 



We are sending you a photograph 



of Stock, Beauty of Nice, a delicate 



pink variety, which has done very 



well for us. They produced full 85 



per cent, double flowers with stems 

 running from 40 to 46 inch. We re- 

 ceived $2.00 per dozen for them in the 

 wholesale market.

THE GLASS SITUATION. 



The firmness noted in our last re- 

 port shows signs of continuing right 

 along until fall, as the American man- 

 ufacturers are approaching the close 

 of the fire, with their product well 

 sold up at high prices, while the for- 

 eign market is kept high on account of 

 i lie possibility of curtailed production, 

 owing to the strike which is expected 

 to develop on May 1st. The American 

 manufacturers on Thursday last ad- 

 vanced their price about 5 per cent., 

 and those who have any glass to sell 

 for future delivery are asking a fur- 

 ther advance. 



On the greenhouse sizes the demand 

 has been especially heavy this year, 

 and orders for regular greenhouse 

 sizes pay a premium.

A VACUUM SYSTEM IN GREEN- 

 HOUSE HEATING. 



Read before the Detroit Florists' Club by 

 Frank A. Simonds. 



In deciding the question of heat for 

 greenhouse work, there are four dif- 

 ferent systems today that can be con- 

 sidered and that cause a diffusion of 

 heat in the building to be heated. The 

 system of hot air circulation, which, 

 owing to its many disadvantages, has 

 been discarded for more modern meth- 

 expensive to generate for the exten- 

 sive demands in this line, and so can- 

 ned be considered. 



Hot water, under a gravity, or nat- 

 ural circulation, also the same medium 

 under a forced or positive circulation. 

 This medium is now used with very 

 satisfactory results, even with the grav- 

 ity circulation, although necessitat- 

 ing, as a general thing, the sinking of 

 the hot water boiler below the ground 

 level, which, aside from the expense 

 of such, has its disadvantages, of that 

 low setting, in not being as conven- 

 ient as if it were on the ground level; 

 this gravity circulation is also very 

 slow. Another point that is often 

 ignored in such a system, and usually 

 to avoid first cost in installing, is in 

 running the mains too small to secure 

 the' best results, and such is only nat- 

 ural, as the excessive size of the 

 mains for such a system increases the 

 enst at an alarming rate. When such 

 a system is installed properly, and is 

 not too extensive, fairly good results 

 are obtained when a uniform, artificial 

 heat is needed. 



Should, however, it be necessary to 

 increase or decrease the temperature 

 on short notice, this system is too 

 slow to respond, as the large amount 

 of water contained in the system re- 

 quires considerable time to absorb, 

 from the furnace located quite a dis- 

 tance away, heat sufficient to increase 

 its temperature all through the sys- 

 tem, while it is, at the same time, 

 radiating its heat through its long 

 lines. The same is true in case the 

 weather moderates rapidly, or the sun 

 bleaks through the clouds and show- 

 ers considerable warmth through the 

 glass, as, while the furnace can be 

 crowded to increase the temperature 

 of the water, it is surprising how long 

 this volume of water will retain its 

 heat after all is done to check the 

 fires, or even the valves are closed to- 

 .^in|> the circulation. 



Again, in extreme cold weather, 

 with high winds and the thermometer 

 outside going away below what was 

 contemplated when the system was 

 installed, and the radiation figured, 

 and an extra amount of heat is re- 

 quired to meet such conditions, it is 

 found impossible to increase the tem- 

 perature beyond a point below that of 

 boiling water, which limits the maxi- 

 mum temperature. 



With the forced circulation system 

 of hot water heating, while the boiler 

 i an be placed on the ground level, 

 and the mains can be made smaller and 

 the circulation beyond the limits of 

 tin- gravity circulation, the same ob- 

 jections are open, to the slow change 

 possible in the temperature. The 

 mains being smaller, and necessarily 

 a smaller volume of water in the sys- 

 tem to heat or cool, reduces this ob- 

 iection to that extent, at the same 

 time, although the water may be kept 

 at a high velocity in the system; on
