International Tillage Brings 

 Bigger Yields and Better Grades 



MANY are the uses, and great is the value of 

 a good disk harrow. More than any other 

 farm tool, its proper use takes the gamble out 

 of crop raising. The perfect seed bed that 

 causes quick, strong germination of the seed, 

 rapid growth of the plant, and even maturing 

 of the crop, cannot be made without a disk 

 harrow. A good one costs so little, and plays 

 such an important part in determining the yield 

 and value of your crops, that its purchase de- 

 serves really serious consideration. 



Knowing the character and condition of your soil 

 as you do, you will know whether to buy a two or 

 three-lever harrow, a tandem, or one of our new lever- 

 less tractor disks, but, whichever style is best for your 

 work, you will find a high-grade, up-to-date harrow of 

 that style in the International line, and of a size, suit- 

 able to your power equipment. We have sold disk 

 harrows for years, but never was the line so complete, 

 or of such high quality, as the line we offer for 1919. 

 The local dealer will explain the value of the many 

 features we have not space to mention here. 



Other useful implements in this line, each built 

 for its own special work, are open end, closed end, 

 and flexible peg-tooth harrows, spring-tooth harrows 

 with single and double end teeth, and one-horse culti- 

 vators with every kind of tooth and shovel equip- 

 ment. These, too, can be seen at the local dealer's 

 place of business, or we will send catalogues on 

 request.

 ment and write us for full particulars about any in 

 which vou may be interested. . n . .„.< A».av;/<o

 Special Reference to the Tomato." 

 They tried the influence of various 

 nitrates on plant development and soon 

 found that they could divide plants into 

 a number of groups, among which were, 

 first, those plants which seemed to be 

 extremely vigorous rarely bloomed and, 



if they did at all, set but few fruils; 

 second, plants which made a very fair 

 growth seemed to be in good vigor, 

 bore very abundantly, producing a large 

 number of clusters of blossoms which 

 readily set fruit. The third set of plants 

 were less vigorous than the second, 

 pruned profusely but set sparingly. 



A chemical analysis of these plants 

 showed that the first group always con- 

 tained an abundance of moisture and 

 soil nutrients. The second group con- 

 tained a decrease in nitrates as com- 

 pared with the carbohydrates, that is 

 sugars and starches, while the third 

 group contained much less of the
