COMPETITION OUR STRONGEST 

 ADVERTISEMENT FOR 



THE TROUTMAN ORCHARD HEATERS 



The one great issue in orchard heating is the question, "HOW MUCH HEAT WILL A 

 HEATER PRODUCE FOR THE QUANTITY OF FUEL CONSUMED?" 



The Troutman Orchard Heaters, owing to tlie center draft combustion, give fifty per cent more 

 heat for every gallon of oil consumed, than any other device on the market. 



There are many things to be considered in purchasing an orchard heater, but the "Consumption 

 of Fuel" is the all important point, and all other matters fade into insignificance in comparison with 

 this one vital feature. The Troutman Heaters equal, if they do not surpass, all other devices in regard 

 to the small details that go to make up an orchard heater. AND IN THE ALL IMPORTANT 

 POINT, THAT OF FUEL CONSUMPTION, they outstrip all other devices. THEY HAVE NO 

 EQUAL. 



Our competitors realize this, and they know they cannot meet us on this ground, and, therefore, 

 they dodge the main issue, bringing the "trivial" features into the limelight, in the hope of deceiving 

 the growers as to the great question. 



The Troutman Heaters are perfected in every detail of construction, and there is no heater that 

 is manufactured with greater care, or that will last longer in practical work. The base protects the 

 bottom of the heater from coming in contact with the ground, which would have a tendency to rust 

 the heater, making it worthless. 



So as to meet all requirements of the orchardists, under all conditions, we manufacture heaters 

 holding from five quarts to six gallons, and that burn without refilling as long at thirty-five hours. 



Our heaters are equipped with wind-proof covers. Our galvanized heaters will last double the 

 length of time and cost but slightly more than plain black iron heaters. Our small fruit attachment 

 is the only heater devised for the protection of small fruits and vegetables. 



In an attempt to sell their device some of our competitors, not being able to meet us squarely on 

 the ground of efficiency, are endeavoring to discredit our heater in some of the minor details. These 

 statements in regard to the Troutman Heaters are absolutely false, and have no foundation, except 

 questionable business methods. 



Has a reader of "Better Fruit" ever known of a business being a success that was carried on by 

 knocking a competitor? We da not know of a single case. 



We wish to caution the growers against advertisements full of "knocks." No concern will ever 

 knock if their article will stand the test of practical work. 

 It has never been necessary for us to belittle a competitor- to sell our goods. We believe in conducting- our business in an 

 honorable manner. We wish to state right here that whenever any orchard heater company wishes a competitive test we are 

 perfectly willing to enter. All that is necessary is to address us at Canon City. Such a communication will receive our 

 prompt attention. We do not believe in issuing challenges, as ninety-five per cent of the challenges issued are for effect only, 

 and the growers know it. 



In response to a challenge, however, in the November issue 

 of this paper, we wrote the letter printed below. The accom- 

 panying table shows an official test between our heater and 

 this other, made several years ago. Affidavits as to this record 

 can be obtained by writing to the chairman of the orchard 

 heating committee of this place, Mr. James Turnbull. 



TFIE TIME HAS COME. WHAT ARE YOU GOING 

 TO DO? 



The time for discussion has passed; the time to act is here!

 pared before your fruit buds are in danger.

 delivery. The Troutman Heaters stand as the "World's stan- 

 dard of efficiency and economy." They are in use in thirty 

 states and several foreign countries. Our customers are num- 

 bered among the most prominent growers of the age. Send 

 for our year book, price list, and bulletin of the government's 

 endorsement, then send us your orders for heaters, rapid 

 lighters, and thermometer alarms. 



Rules for Competitive Orchard 

 Heating Tests 



Hoiu Orchard Heating Tests Should Be Made 



First, select an orchard where there is at least 

 five acres e.xactly alike as to the number of trees 

 to the acre, age of trees, etc. 



Second, give each kind of heater one acre of 

 ground to heat. 



Third, see that the. blocks of heaters are not 

 within 200 feet of each other, to prevent any possi- 

 bility of one block affecting the other. 



Fourth, give each block of heaters 100 gallons of 

 oil, and fill each heater with same quantity of oil. 



Fifth, place the number of pots to the acre that 

 is recommended by the manufacturer. 



Sixth, place the heaters at equal distances over 

 the acre. 



Seventh, continue the test for six hours. 



Eighth, use nothing but government, or govern- 

 ment registered thermometers, and see that all are 

 compared with one another. 



Xintli, use at least three thermometers to the 

 block. 



Tenth, place one thermometer in the very center 

 of the center square of heaters in each block. 

 Place the other two thermometers wherever desired, 

 but be sure they are in the center of the square of 

 heaters it occupies, and be sure the thermometers 

 are hung in the corresponding square in each block 

 of heaters. See that the thermometers are hung 

 the same distance above the ground in each case. 



Eleventh, take temperature readings at least once 

 every half hour. 



Twelfth, measure any oil that may be left over 

 after the six hours' burning. 



Thirteenth, make the test on a still night. A 

 repetiticin of the test may be desirable on another 

 niglit. 



T^et the result of the test be the average temper- 



ature during the six-hour period, and the amount 

 of oil consumed. 



In placing your outside thermometers have tw-o 

 or three, placed on different sides of the heated 

 block, not closer than 200 feet to any heated block. 



Our committee found that to get accurate results 

 the above rules had to be adhered to.

 Orchard Heating, James Turnbull. chairman, igoS.

Gentlemen : We notice in the November 

 issue of "Better I'ruit," on page 67, your 

 challenge to all orchard heater companies 

 to a demonstration with not less than 300 

 heaters. We also notice in the "California 

 Cultivator" of November 17, on page 470, 

 your statement that your competitors have 

 refused to compete with you. 



We take pleasure in accepting your chal- 

 lenge for a competitive test; said tests to 

 be made by disinterested parties and along 

 the lines of the rules which we enclose. 

 These rules are compiled with a view of 

 being fair to all. 



The test should be made along the lines 

 of how much heat each heater will produce 

 with a certain quantity of fuel. 



At any time you desire, we will be 

 pleased to have your representative meet 

 our representative and arrange the details 

 of said competitive test. Yours truly.

LARD PAIL HEATERS 



PRICE TWELVE CENTS 



This heater is the equal of all 

 other heaters not having the center 

 draft. That is to say, it will produce 

 the same amount of heat for every 

 gallon of oil that other devices do. 



Professor O'Gara says in his arti- 

 cle in October "Better Fruit" that 

 THE LARD PAIL HEATER IS 

 TFIE EQUAL OF THE BOLTON 

 OR OTHER SUCH HEATERS. 

 Then why buy a more expensive 

 heater. This heater holds five quarts 

 of oil. If vou want a cheap heater 

 buy this one. 



HEATING TEST 



Made at Canon City A'oi'ember 2i, IQ08, by 

 Orchard Heating Committee. 



Test made on two separate acres, 100 pots to the 

 acre. One-half Troutman pots and one-half Bolton 

 pots were used. All pots placed at equal distance 

 apart and all filled with one gallon of oil. 



Registered thermometers used, hung in the cen- 

 ter of a square of pots, hung inside and outside of 

 the heated area, as per following headings. All 

 pots lighted at 7:40 p. m. Rows of pots, north 

 and south : Troutman to the west, Bolton to the 

 east. Slight westerly wind. Temperature of out- 

 side air registered by thermometer several hundred 

 feet west of pots. 



Ground frozen and trees bare of all foliage, 

 making it harder to raise temperature than when 

 trees are in bloom or leaf.
