THEaVERY LATEST IMPROVEMENT IN 



Fruit Graders 



Are the Two, Three and Four Grade 



IDEAL 



FRUIT GRADERS 



Never gets out of adjustment or causes any loss by bruising the fruit. 



The sizing is by diameter or cheek measurement, the most perfect way fruit 

 should be sized . 



We build the Ideal Fruit Grader in six sizes to suit any need, from the larg- 

 est growers and packing houses, who require a large output each day, to the 

 individual grower with small tonnage. 



We have designed our machine so there is absolutely no bruising of the 

 fruit in any manner. The machine is very simple in construction, with nothing 

 to get out of order or out of adjustment. Does not make the least noise, as 

 there are no metal parts coming in contact with each other to cause a lot of 

 wear and trouble. 



The grading is done by elastic bands revolving crosswise of the belt that 

 carries the fruit along the machine until it arrives at the proper bin, where it 

 comes in contact with this elastic, which rolls it off gently into its proper bin 

 without injury. 



It will do Perfect Work on Apples, 

 Pears, Peaches, Oranges or any 

 other fruit having similar shape 



This season's crop is such that we have had to double our stock to handle 

 our orders, as we are replacing other machines of other makes, which have cost 

 much more than what we are asking for ours. 



It will pay you big to write us to get more information and prices before 

 you buy, for our machine will prove very satisfactory, as it has to many others 

 for the past few years. 



We have one of the most complete shops with the best of machinery to 

 build every part over a pattern to get them exact. 



Write us for prices, stating your needs: then we will gladly quote you prices 

 on any size machine you need. 



We also carry in stock the Bryant Clamp Warehouse Truck, which will save 

 you the price many times over each season in labor. 



Write us and order early.

With these few of the many advan- 

 tages derived from the use of cover- 

 crops in mind we will consider in brief 

 their value as found from the stand- 

 point of increasing the nitrogen content 

 of the soil. 



For our conditions in Montana ex- 

 perience has shown that humus is al- 

 ways needed, and while it may be 

 secured by using a crop of oats, wheat 

 or rye, it is also possible to secure 

 nitrogen at the same time by using a 

 leguminous crop. For this reason clover 

 and peas have been selected as our 

 best crops for use in building up the 

 orchard soil. 



At the Horticultural Substation in the 

 Bitter Root Valley an experiment has 

 been carried on since 1908 to demon- 

 strate the value of cover crops of clover 

 and peas to increase the nitrogen con- 

 tent of the soil. The system followed 

 was to seed clover, in May and plow 

 under the fall of the following year. 

 With the peas which were also sown in 

 May the turning under was done the 

 same fall. In order to successfully con- 

 trol the weeds it was found necessary 

 to clean cultivate every third year. The 

 part of the experiment where clover 

 was used consisted of two plots of an 

 acre each. One plot all the growth 

 was plowed under, and on the other all 

 the growth was removed. With the peas 

 all the growth was plowed under. A 

 fourth plot was used as a check plot 

 and was clean cultivated continuously. 



The first analysis was made in 1916 

 after the experiment had been in pro- 

 gress for eight years. The nitrogen 

 content of the first two feet of soil in 

 the plot which had been clean culti- 

 vated during this time was 1514 pounds, 

 while that of the plot which had had 

 the clover — tops and all — plowed under 

 was 3019 pounds, or a variation of 1505 

 pounds. The comparison may mean 

 more with the variation stated in terms 

 of a common nitrogenous fertilizer. To 

 bring the nitrogen content of the clean 

 cultivated plot up to that of the plot 

 which had been cover-cropped with 

 clover would require an application of 

 approximately 9400 pounds of commer- 

 cial fertilizer. 



The second clover plot which had 

 been treated in the same manner but 

 had had all the growth removed, leav- 

 ing only the roots and some stubble, 

 showed a total nitrogen content per 

 acre of 2167 pounds or 882 pounds less 

 than where no growth had been re- 

 moved, and 653 pounds more than the 

 clean cultivated plot. 



The plot on which peas were used for 

 a cover-crop showed a total content of 

 2375 pounds of nitrogen per acre or 861 

 pounds more than the clean cultivated 

 pint and 641 pounds less than the plot
