south rafters and 9-foot north rafters. 

 Houses No. 4, 5, 6 and 7 are each 16x 

 90, extending only half as far west as 

 the other houses. The smaller houses 

 are the same height as the larger ones 

 and are also three-quarter span. The 

 houses are on a hillside, with No. 1 at 

 the lowest part of the slope. 



The distance from the boiler to the 

 point where the flow pipe enters the 

 houses is about sixty feet. After enter- 

 ing, the house, the 3-inch flow pipe is 

 laid on the ground, sloping gradually 

 uphill to the end of house No. 1; then 

 uphill across Nos. 1, 2 and 3; then half- 

 way back on No. 3, continuing uphill; 

 then crossing the ends of Nos. 4, 5, 6 

 and 7. The branch lines are taken from 

 this and distributed through the houses, 

 two under each gutter and the rest sus- 

 pended from the roof. All the branch 

 lines slope back toward the boiler and 

 connect at the east end of the houses 

 with the 2-inch return. 



Each branch line is fitted with a 

 globe valve of the same size as the 

 pipe, at the west end, and with a %- 

 inch check valve at the east end. Is a 

 %-inch check valve large enough for 

 pipes of this length? 



The crops are grown on ground beds'. 

 Lettuce is grown in fall and winter. 

 In the spring Nos. 1, 2 and 3 are in 

 tomatoes; Nos, 4, 5, 6 and 7 are in 

 cucumbers. A temperature of 50 de- 

 grees in zero weather is desired for 

 Nos. 1, 2, 3, 4, 5 and 6, and 60 degrees 

 for No. 7, in which the cucumbers and 

 tomatoes are started. There is a parti- 

 tion between Nos. 3 and 4 and another 

 between Nos. 6 and 7. The houses are 

 the old wood-frame style, moderately 

 exposed and not in first-class repair. 

 From twenty to twenty-five pounds of 

 steam are carried at the boiler during 

 severe weather; yet at times the sys- 

 tem clogs completely with water. 



It seems to me that a %-inch check 

 valve is too small for the branch lines, 

 particularly as several feet of %-inch 

 pipe are used in connection. I have 

 thought of changing these to 1-inch 

 check valves and adding two IVi-inch 

 pipes to each house, placing them under 

 the gutters. Kindly advise me at your 

 earliest convenience. V. S. G. 



WHEN YOU BUY-OIT A KROESCHILL 

 ■THE BOILER OF UNEQUALED FUEL ECONOMY' 



The sketch shows three lV4-inch pipes 

 in houses No. 4, 5 and 6, which are 

 sixteen feet wide, and a varying num- 

 ber in the other houses, which provide 

 about the same relative radiation, ex- 

 cept in house No. 1, which has a 3-inch 

 main in addition to three returns, and 

 house No. 7, where there are two 2-inch 

 and three 1^/4 -inch returns. 



It is evident at the start that most 

 of the houses are deficient in radiating 

 surface, but this would be corrected by 

 the addition of two 1%-inch pipes in 

 each house, as proposed. This, of course, 

 would not prevent the backing up of 

 the water in the pipes, but the substitu- 

 tion of 1-inch check valves would un- 

 doubtedly help this to some extent, 

 although a %-inch valve is large enough 

 to carry the drip water from a 1 %-inch 

 pipe 180 feet long. I would prefer to 

 put in globe valves in place of the 

 check valves and would leave them out 

 entirely in case of the pipes to be added 

 to the houses, unless some of them are 

 to be unused for considerable periods 

 in the winter. 



I believe this would correct the diffi- 

 culty, provided the water level in the 

 boiler is six feet below the coils — and 

 possibly a difference of four feet in- 



You will never be disappointed with a KROESCHELL Boiler. 

 Read what others say who have used different kinds. 



Get the Kroeschell First 



Several years ago Mr. Ponting corresponded with us In regard to 

 the Kroeschell Hot Water Boiler, but was persuaded to install two 

 sectional cast Iron boilers which were claimed to be superior to the 

 Kroeschell. 



In the meantime we placed a number of Kroeschell Boilers in the 

 immediate vicinity of Mr. Ponting, and he could not help but notice 

 their great efficiency, and last year, while at the convention, he placed 

 his order for his first Kroeschell. The following letter speaks for 

 Itself: 



"We like the Kroeschell Boiler very much. It gives entire satis- 

 faction, and It is so easy to tire. I will trade you the two cast Iron 

 sei^ional boilers for another like the Kroeschell I have."

Kroeschell Replaces 4 Cast Iron Boilers 



Previous to 1909, Mr. Schultz, of Menominee, Mich., heated his entire plant with 

 cast iron boilers. It had been claimed that cast iron boilers are superior to the 

 Kroeschell. Mr. Schultz is now heating 18,000 sq. ft. of glass with the Kroeschell 

 which was installed in 1909, and they are required to fire same only twice a night. 

 The following letter speaks for itself: 



"We do not have the least trouble to maintain about 60 degrees in the coldest 

 weather. Your Kroeschell Boiler Is the best I ever had. Before I heard ai>out .vour 

 boiler I had four cast Iron boilers, and I would not part with the Kroeschell for a 

 hundred cast Iron boilers now."

Kroeschell Replaces 2 Cast Iron Boilers 



The Marysvllle Floral Co., of Marysvllle, O., installed a No. 4 

 Kroeschell Boiler in 1905. Previous to this time they used cast iron 

 boilers. The following letter speaks for itself: 



"Has the Kroeschell given entire satisfaction? TES! We had 

 two ^ast Iron boilers, but yours proved by far the best. Yonr boiler 

 has alread.v outlastetl the two cast Iron boilers by five years, and all 

 the expense that we have been put to was a smoke dome."

Kroeschell Replaces Cast Iron 



The range of C. Peterson & Son, at Escanaba, Mich., was formerly heated by ca«t 

 iron boilers. Last season this firm installed their first Kroeschell, a No. 6, wh"h '" 

 now heating 13.000 to 14,000 sq. ft. of glass. They state that they fire these ' '•'% 

 three to four times during the night in zero weather. Under date of June 28, Iwi*' 

 they write as follows: 



"The Kroeschell Boiler has given better satisfaction than any other boiler we h*^ 

 ever had. For years we have Hred many different boilers, and really never coiiM s^ 

 one that we might say was entirely satisfactory — there was always something '*''''.'",*_ 

 but now since we have tried the Kroeschell, we have solved our boiler propo'"'"^^ 



We have a ( ) cast Iron sectional boiler here, only used two years, ana " 



wish we could get rid of It and put In another Kroeschell In Its place." „^
