each of them with four. 2-inch returns. 

 A third 2% -inch flow pipe should be run 

 about four feet below the ridge and 

 connected with four 2-inch returns to 

 be brought back under the benches. If 

 it is not possible to use the four returns 

 under the middle benches, I would run 

 a 3-inch flow pipe upon each plate, with 

 six 2-inch returns on each wall below 

 the glass^ 



The reason why large flow pipes run 

 downhill are better than small pipes run 

 uphill, is because the circulation of the 

 water in the pipes is due to the differ- 

 ence in the weight of the water in the 

 pipes, considering on one side the water 

 between the boiler and the highest 

 point of the system, and on the other 

 that between the highest point of the 

 system and the boiler; or, in a system 

 piped as described by the inquirer, in 

 the flow pipe on one hand and the re- 

 turns on the other. It can be seen, 

 then, that as the water in a small up- 

 hill flow pipe cools it becomes heavier 

 and acts as a sort of drag on the cir- 

 culation. When the highest point of 

 the system is nearly over the heater, 

 the cooling of the water is almost en- 

 tirely in the downhill portion of the 

 system, and this results in a "pull 

 altogether" which causes a rapid cir- 

 culation. 



A reason for having medium large 

 flows is that the circulation is better 

 than in small pipes, and it makes it 

 possible, considering them principally 

 as pipes to carry the water to the coils, 

 to distribute a larger proportion of the 

 heat near the floor of the greenhouse, 

 where it would be more effectual than 

 when near the glass. Of course it 

 would be possible to use one 4-inch flow 

 in the present case, instead of three 

 214-inch flows, but the weight of the 

 water in proportion to the radiating 

 surface would be several times greater 

 and the smaller pipes would be less con- 

 spicuous in a small house. I prefer to 

 have the ventilators open away from 

 the prevailing strong winds. 



TO LOOSEN SOOT IN FLUES. 



Please let me know whether there is 

 any mineral that could be burned in the 

 fire-box of a boiler so as to clean the 

 flues or loosen the soot, which is hard 

 and of a gummy nature. J. J. S. 



I do not have in mind any feasible 

 way to loosen soot or prevent its forma- 

 tion in the flues. In some cases scraps 

 of zinc are thrown into the fire and 

 this is more or less effective in small 

 heaters, but I do not consider it feasible 

 in large boilers.

Our Square Paper Dirt Bands are the original 

 of all that are on the market today. All others 

 being sold are Imitations of these we advertise, 

 and some of the Imitations being soM -are made 

 of cheap paper, costing only about half as much 

 as our hesTy stock. We sell no experiments. 

 Ours have been tried out by long use In the green- 

 house. They will stand up In any wet and heat

Gentlemen: In reply to your query would state 

 that I planted seedling stock plants and snap- 

 dragon cuttings In the first lot of bands that I 

 received from you early In January. 



We took- some of these out and planted them 

 where they are to remain about the 16th of 

 February. They made a GOOD GROWTH while 

 In the bands, and transplanted AS THOUGH they 

 bad never been moved at all. 



I have now about 14.000 carnation plants 

 ■tsrted In 2-ln. bands which are making a RAPID 

 GROWTH, scarcely losing a plant In transplant- 

 Ing from the sand. 



I also have about 20,000 aster plants trans- 

 planted In 2-in. bands which can stay there till 

 time to plant out of doors WITHOUT F^AR OF 

 BECOMING ROOT BOUND, as would be the case 

 If I used 2-ln. pots. 



Plants SELDOM BECOME ROOT BOUND 

 enough to Injure them IN THE DIRT BANDS, 

 and DO NOT REQUIRE NEAR THE AMOUNT 

 OF ATTENTION tliat a pot plant does. In water- 

 ing, shifting, transplanting, etc. 



I make my bands and set them in flats, as I 

 make them up, each flat holding 117. 



When we get crowded Indoors It takes but a 

 short time to move the flats to a cold frame, 

 where we harden them off before setting them In 

 the fleld. 



One man can set MORE THAN ANOTHER 

 TIME AS MANT (twice as many) plants In the 

 fleld from these bands and flats than he can from 

 pot s, and after he Is throneh DOES NOT HAVE 

 THE BOTHER OF GATHERING UP, CLEAN- 

 ING, and STORING AWAY A LOT OP POTS. 



I believe anyone using these bands ONOB 

 WILL BECOME A REGULAR CUSTOMER. 

 Tours truly, 



H. B. Weaver.

2n<fo MORE BLOSSOMS 



on plants raised in Square Paper Pots tbaa oa 

 plants raised in clay pots of same size. 



There were 456 stems of blossoms on 40 plants 

 raised In 4-lnch Square Paper Pota and 105 stems 

 of blossoms on 40 plants raised In 4-lnch clay 

 pots. 



The above was taken from the following report 

 in the Market Growers' Journal, January 1, 1014, 

 page 6. 



When set In the field May 16th, the root sys- 

 tems of the plants from the 4-inch square paper 

 pots were 4-inch cubes (64 cubic Inches of soil 

 and roots) and from the 4-lnch clay pots the root 

 systems contained 31 cubic Inches of soil and 

 roots (the amount that a 4-lnch clay pot holds). 



The third count of blossoms was made June 27, 

 42 days after the plants bad l>een set In the fleld. 



The plants from the square paper pots were 

 then more than twice as large and vigorous as 

 those raised In clay pots. 



All plants raised In square paper pots are 

 larger and more vigorous than those raised In clay 

 pots, because they have alMut double root room 

 for the same size pots. 



Measure the two pota and yon will find that 

 the 4-lnch square paper pot holds as much soil 

 as two 4-lnch clay pots. 



It Is the same with square dirt bands, which 

 are square paper pots without bottoms (the bot- 

 toms being furnished by old newspapers spread 

 on the bench). 



The theory that It Is only necessary to have a 

 big top to the plant has been proved mlsleadlni:. 



There must be a big root system to push tl:e 

 top or the plant will grow slow and small. 



Try some square paper pots or dirt bands with 

 your clay pots and see If you can afford to use 

 any clay pots. 



Some of the florists around Philadelphia are 

 using large numbera of square dirt bands ana 

 paper pots. 



We have shipped to Mr. P. B. Dllks, Brlde<(- 

 burg, Phlla., Pa., 150,000 2-lncb square dirt bands 

 and 20.000 S-lnch sqnare dirt bands; to Mr. Geo. 

 W. Dllks, Frankford, Pa., 10,000 2-Inch square

 to Mr. M. H. Hostetter, Manhelm, Pa., 20,000

3939^0 MORE EARLY FRUIT 



120 early tomato plants reported in Mark't 

 Growers' Journal, Jan. 1, 1914, raised in 4-ln'^u 

 clay pots (31 cubic Inches of soil and roots), had 

 yielded np to Aug. 11 7% peach baskets— $4. i5 

 worth of ripe tomatoes, while 120 plants raised is 

 4-lnch SQUARE paper pots (64 cubic Inches of 

 soil and roots), had yielded 33 peach baskets— 

 $23.60 worth of ripe tomatoes — 393 per cent more.
