 the most remunerative results. For period of five years, on four different fields. the Utah experiment station has obtained the following average re- suits with wheat:
 Yield per acre Depth of Flowing. Bus s inches ..............--..... l3- l 10 inches ..-..-----..--..------- -lf.u I5 inches 13.4 20 inches. including blowing and sub
 soiling .lS-4
 On one of the fields included in the four fields referred to in the above table, blowing to a depth of 1h inches gave the highest yield-23.4 bushels per acre. On the other three fields blowing over 10 inches in depth gave the highest yields, yet the difference was not sufficiently large to offset the extra cost of the deeper blowing and subsoiling On two other fields, during 1907 and 1908, the following average yields were obtained from different depths of blowing:
 Yield per acre
 Soil Preparation Bus. Disced, but not plowed.. Flowed inches eep...............-.--191 -191 Flowed and subsoiled Is inches deep. -27.4
 In 1909 this work was again repeat ed on another farm with the following results:
 Yield per acre
 Soil Treatment. Bus. Flowed 5 inches deep.................-...1 10 Flowed 10 inches deep. 13 Flowed and subsoiled 15 inches deep. IS SI1I 4
 Summarizing these results, Prof. l.. A Merrill, in a recent bulletin, report ing seven years investigations in dry farming methods, says: The writer's opinion is that on deep, heavy clay soils. blowing to depth of ten inches will insure as good and possibly better results than blowing to a greater | depth, but that on lighter soils an oc- casional blowing to a depth of fifteen l to eighteen inches is advisable"
 While the results above mentioned | are not applicable to all sections, and | we would not, of course, recommend | blowing the land to a depth of ten | inches regardless of local conditions, | we believe they are of value in call. ing the attention of our readers to the ldCI lAdl tue average IS AOt blowing his land deep enough. Those who are blowing their stubble lands this fall in anticipation of droughty conditions next year should blow their land from one to two inches deeper than they have been doing in the past Those who have been blowing six or seven inches deep will undoubtedly improve the producing power of their land by blowing seven or eight inches this fall, while those who have been in the habit of blowing only four or five inches in depth may well blow two inches deeper. This, of course, is only a general statement and each person must determine for himself what he may reasonably expect from deeper blowing. However. as a general propo- sttion there Is no question but that we have reached the stage when we must work our land deeper and give 1t more surface cultivation.
 If deeper blowing conserves mere moisture in the arid belt, there is no reason why it should not also do the same in the humid belt. No one knows, of course, whether next year will be dry one or not, but even if we should have a normal rainfall our soils will still be short of moisture We never have what is ordinarily called a wet year following a dry year. Let us pre- pare for a shortage of moisture next year; it will be money in our pockets
