BETTER FRUIT

instead of 25 



^m Ir \ve ■v^^ere to pick out only one 

 ^^^ point in the Caterpillar Tractor, 

 to snow tne improvement in tke new 

 moaels, it -would be this: — 5 pieces in the 

 track unit -where there -were 25 three 

 years ago — less -wear, no -svaste of po-wer, 

 longer lire. 



If we -were allowed only one argument to 

 put up to a Caterpillar prospect, it -would be the 



argument of quality of right design of hest 



grade material and -workmanship of "stand- 



up-iveness. 



The Caterpillar has heen 10 years in the 



field 10 years to he tried in 10 years to he 



improved in. 



We re looking for some good live tractor 

 prospects to let loose some of our enthusiasm 



on. If you re the man drop us a line ask for

Radium and Plant Life 



A very low radio-activity exerts on plant life a healthful stimula- 

 tion of all the vital processes, and assists in building up the soil so that 

 all growing things can be at their best — healthy, thriving and vigorous. 



This radio-active material is the residue from the process of radium 

 extraction and contains a definite amount of radium element. When 

 applied to gardens, trees or crops the results are most gratifying. 

 Radium has an influence, described by scientists, as very similar in its 

 effects upon vegetation to the ultra-violet rays ofthesun,and as applied 

 to growing things is the most important discovery of the century. 



We have an illustrated book sent free upon request 

 showing what has already been accomplished.

caused the apples in many sections to 

 mature far more rajjidly than usual, 

 and as a result much of the fruit is 

 being stored at a more advanced stage 

 of maturity than in the past. High 

 temperatures affect the fruit after 

 picking even more than during their 

 life on the tree. It has been deter- 

 mined that apples mature as rapidly, 

 if not a little more so, off the tree as 

 ujjoii il, if held at the same tempera- 

 ture in both cases. Therefore, unless 

 the fruit is stored at a low temperature 

 immediately after it is picked, its vi- 

 tality and possible length of life will 

 decrease very rapidly. Many growers 

 pick the the fruit at the proper time, 

 but allow it to remain in the orchard 

 for days, subject to alternate heating 

 and cooling — con(htions most unfavor- 

 able to keeping quality. Even after it 

 is removed to the packing house it is 

 often many days before it is packed 

 and stored at the proper temperature. 

 The effect of such delayed storage in 

 contrast to immediate storage has been 

 well brought out by the Department 

 experiments. Boxes of fruit that had 

 been picked, packed and stored within 

 a few days were compared with boxes 

 of exactly the same fruit, picked and 

 packed at the same time, but delayed 

 for two weeks before storing. This 

 experiment has been carried on with 

 a number of varieties of apples in the 

 principal fruit sections of the North- 

 west for several years, so that approxi- 

 mately average results have been 

 secured. The following table gives 

 a sunnnary of the results in four 

 varieties:

Delayed 17.0 31.4 7.9 18.2 



Note that ten days after the first 

 withdrawal from storage, 4.1% of the 

 immediate lot showed bad scald, as 

 against G.~7c of the delayed lot, and 

 ten days after the last withdrawal the 

 difference is still greater, 20.0% of the 

 immediate lot, against 31.4% of the de- 

 layed. The rate of decay showed sim- 

 ilar differences at the same periods — • 

 1.1% of the immediate lots, ten days 

 after the first inspection, and double 

 that amount in the delayed lots, and 

 ten days after the last inspection 

 12.8% in the immediate, with 18.2% 

 in the delayed fruit. 



This table needs little comment, for 

 it shows plainly that at each of the 

 inspections tiie amount of the deteri- 

 oration was decidedly greater in the 

 delaxed storage lots, though, as pre- 

 viously stated, the delay began after 

 the fruit had been packed. Undoubt-
