The three greenhrnises will re(|iiire a 

 total of about 4,i'(iii sipiare feet of radia-

 feet of radiation and will take care of 

 this amount uinler conditions stated in 

 your inquiry, still the writer would ad- 

 vise considering the next size larger 

 })oiler, namely a No. C^. capacity 4,.'50(( 

 scpiare feet of radiation, which would do 

 the work more easily and with less at- 

 tention in the way of firing. This he 

 would especially recommend since the 

 (lili'erence in price between the two boil- 

 ers is but $-2>.K

Gentlk.men:— You can strongly and unhesitatingly recommend the 

 " Eclipse " piston type reducing valve to florists. We have two purchased 

 of you last year. We would not have them out for double their cost and 

 find them as sensitive as a watch. We will be in Chicago soon to take up 

 the vacuum system with you. Yours truly,

 ture of oL* degr<'es in weather '20 degn'es

Ill lefeieiice to the main leads, would 

 state that tile number of leads will be 

 deieniiiiied by the positions; that is. if 

 your houses are so ;irr;inged th.at the 

 le;ids will be side by side, we wDiihl ad- 

 \ ise ninniiig from the lx)iler with one 

 large tlowpi|(e of siiHicient capacity for 

 the work. Should your boiler be located 

 in the center of the three houses we 

 would advise two Hows. Tln^ same may 

 be said of the main returns. It is also 

 more economical to install, as well as 

 more practiciil, one large niiiiii flow ;uul 

 leturu where this is possible. 



A UNIQUE NATURAL PRODUCT. 



( )ne of nature's most wonderful and 

 uiii(|iie products is asbestos, a material 

 now liirgely used for covering greenhouse 

 boilers ;tnd tlowpip<'s to conserve heat. 

 Prior to Is.ld, it was looked ujion prin- 

 cipally as a curiosity, although (harle 

 nmgne ( Koman emperor from S(l() to 814 

 A. I).) is said to have had a table cloth 

 made of asbestos, which he (leaned by 

 throwing into fire. 



There are two varieties of commercial 

 asbestos, known as amphibole and chry- 

 sotile. The former is used only to a com- 

 paratively small extent, as the fibers are 

 short and without tensile strength and 

 are, therefore, not suitable for manufac- 

 turing many of the asbestos products. 



Mention The Review when you write. 



Amphibole is used to some extent in 

 cements, but is not widl adapted even for 

 that pur}iose. ('hrysotile, on the other 

 haial. has a strong and silky fiber, which 

 adapts it for such imiterials as asbestos 

 fabrics, household utensils, tli(>ater cur- 

 tains, clothing for firemen, etc. 



In (ieiniany. asbestos is known as 

 steintiischs (stone lliix) and the miners of 

 (^iieliec give it quite as exjtressive a name 

 - pierre coton (cotton stone). 



Asbestos is mined in open pits, similar 

 t<i stone (piarries, and although it is 

 found in all parts of the world, the mines 

 ill (Quebec. Canada, ;ire the most famous, 

 yielding eighty-five per cent of the 

 w(uld 's supply of (hrysotile. Probably 

 the largest of these mint^s is that owned 

 by the IF. \V. Johns-Manville Co., of New 

 York. In 1879 the output of the (Quebec 

 mines was MOO tons, which has steadily 

 incrciised vear by vear to 50,000 tons in 

 190."). 



RETURNS TOO SMALL. 



Will you kindly assist us in locating 

 the trouble with our hot water heating 

 system? On the north side of the green- 

 house are three il-inch flows supplying
