Success in Farming 



Success is the prosperous termination of 

 any enterprise — prosperity . 



Success is not just getting along halfway 

 — it's beating the game, and winning — it's 

 prosperity. 



Success in farming requires the use of 

 every means to raise bigger crops at less 

 e xpense — to get the 

 work done at the 

 right time , at the 

 lovyest cost. 



Success means 

 getting the soil in 



good humor, so it will 

 produce big crops and 

 will not be exhausted. 

 Success in farming 

 means getting big tasks 

 done with least effor t 

 and least expense. 



You can use a tractor to your advan- 

 tage on your farm. 



Success in farming means the use of mod- 

 ern machinery— the saving of human effort 

 by utilizing mechanical power— the saving 

 of money by introducing one machine to do 

 the work of ten men and forty horses. 



Success in farming is holding the young 

 men in the country instead of attracting 

 them to the over- 

 crowded city. 



Success in farm- 

 ing is made possi- 

 ble by the tractor to 

 plow and harrow 

 and cultivate and 

 haul the thresher 

 and the grain, in 

 the orchard and the 

 rice field. 



Let us prove to you why you should 

 have a money-making tractor.

The Codling Moth 



Presented at California Fruit Growers' Convention, Palo Alto, July 28, 1915, by A. L. Melander, Pullman, Washington 



HOW many times shall we spray 

 for the codling moth? That is 

 the question. ^Vhether wo be- 

 lieve in strong or weak spray, misty 

 or driving application, low or liigh 

 pressure, neutral or acid arsenate, and 

 whether we supplement the spraying 

 with other contiol practices, such as 

 cultivation, lliinning and banding, we 

 are all inteiested in how often, or 

 rather how few times, and when to 

 spray. Ten years ago fruitgrowers in 

 Washington were averaging seven sum- 

 mer spi'a>ings for the codling molli, 

 using hand pumps at a pressine of 

 fifty pounds, Vcrmorel nozzles, long 

 spray poles, strong iiaris green and 

 spraying from the ground, and getting 

 H^ per cent of worm-free fruit to repay 

 their trouble, the culls being for the 



most part calyx wormy. Contrast with 

 this method the system which these 

 same growers now practice: Power 

 sprayers maintaining 2,')l) iiounds pres- 

 sure, clipper nozzles set with a crook- 

 joint to 8-foot rods, weak arsenate of 

 lead and the spraying done from an 

 elevated platform. Tiie two methods 

 have little -in connnon beyond aiming 

 to check the codling moth, >el the 

 growers now are able to eliminate lialf 

 their applications and add an exira 10 

 per cent to their crop. Tlie cliange 

 resulted simjily from apph ing the prin- 

 ciples of efTiciency to this i)liase of 

 orchard management. 



A decade ago when man.\ growers 

 were si)raying twice each month, we 

 showed that in the Norlli the coclUng 

 moth worked in well-defined periods. 



In the irirgateil districts no apples 

 became infested during the liist half of 

 July, in which case a si)ra.\ ing on July 

 1st was so much effort wasted. This 

 eliminated one spraying. The substi- 

 tution of arsenate of lead for paris 

 green gave an adhesive material good 

 for a month or more, thus eliminating 

 otlier sprayings. Hence a spraying 

 when the first brood jiatched, another 

 after mid-July at llie onset of the sec- 

 ond itrood and anollier about Septem- 

 ber 1st for late second brood and a 

 partial third brood, took care of the 

 difhcult part of the program. The 

 object of these three application is to 

 coat the fruit willi poison in advance 

 of the hatching of the worms so that 

 the lirst meal taken by them will be 

 their last also, .^pparentlv then these
