DRY FARMING CONGRESS. 205 



for the listed in this case only 21 bushels, although they show the lower 

 moisture contents, which might indicate it raised a big crop, but it is 

 evident that the low yield or low moisture contents probably had some- 

 thing to do with the yield. 



The next slide shows the fd^-m of moisture conservation experiments 

 at Hymore. No\v B was a plat which grew corn this year, which was 

 fallowed last year, and starts high, as a fallowed plat should start, and 

 gradually decreases as the crop develops. C, which was cropped last year, 

 starts low, like the others, and does not gain very much during the wdiole 

 season until at the end, where it has finished development. The yields in 

 that case were 31 bushels for the spring plowed corn, 28 for the fall, 

 whereas on the summer fallowed we got onl}" 17 bushels. In other words, 

 after summer fallowing the preceding year, taking two 3''ears to grow one 

 crop of corn, we got 17 bushels, as against 30 bushels from spring and fall 

 plowing — the same as at North Platte. 



A DELEGATE: What was the rainfall? 



DR. BRIGGS: The slide doesn't show it. I think it was about eighteen 

 inches, but I can't tell you positively. 



The next slide shows the conditions at Dickinson, in North Dakota, 

 on the farm. We had a late season here and early frost this year, so 

 that it was not possible to mature the corn. You will notice that the fal- 

 lowed plat gave the lowest yield. 



The next slide shows at Edgeley, further east in North Dakota, 

 showing the moisture conditions of the different wdieat plats, the spring 

 plowed, fall plowed and fallowed. Here the fallowed plat starts high, as 

 it should, and it is maintained at this point, and the new fallow, starting 

 in this year, the first determination we have, maintains itself with the 

 others, and shows an average gain here of 2, 4, 6 and 7 per cent at the 

 end of the season. You will notice in this case that there is a more sub- 

 stantial gain over the spring and fall plowed than there is over the fallowed, 

 the moisture running, from this point on, very similar. 



The next slide shows the moisture conservation of oats at Edgeley. 

 Here we have a similar condition, the fallow starting high, this being the 

 plat we fallowed last year, sowing it to crop during the present season. 

 This started high, showing a decided gain in moisture in this particular 

 case all through the season. You will notice also this is one exception 

 from all the rest, that fallowing in this particular case was justified, 5'ield- 

 ing twice as great as the spring plowed land, and almost twice as great as 

 the fall plowed land. 



* This represents simply a portion of the moisture determinations which 

 in turn represents a portion of the work which we are doing on these 

 farms in connection with the investigations which I have just described. 

 I thank you very much. (Applause.) 



CHAIRMAN BURRELL: This concludes the papers for the evening. 

 The Chair will entertain a motion to adjourn.
