of our house, is a chance for its expression. My hope lies in the child, and 

 by improving the front and back of our lot, the child is benefited most. 



To create higher real estate values, to relieve congestion, to improve 

 sanitary conditions, and to teach the child some of the possibilities of na- 

 ture, are a few of the benefits made possible by planting a very few 

 shrubs or flowers and then directing the child in their maintenance. 



SPRAYING MACHINERY— ITS USE AND ABUSE. 

 By George P. Weldon, N. Collins, Colorado. 



Spraying is conceded to be one of the most important operations of 

 orchard practice. The manner in which it is done very often determines 

 the quality of the crop of fruit that is produced. The very best results 

 in spraying are hard to attain with the use of poor machinery. 



In those sections which are best adapted to the growing of fruit, and 

 where the industry has assumed a stage of great commercial importance, 

 the gasoline power sprayer is much more generally used than any other 

 type of spraying machine. To say that this machine has revolutionized 

 the spraying business, is literally true. Had the orchardists in our fruit 

 sections to depend today on the old-fashioned barrel and tank pumps, 

 manipulated by hand, the high degree of efficiency possible with a modern 

 gasoline power outfit could not be attained. 



Wherein does the gasoline power sprayer differ from the old type of 

 hand pump so that its use results in greater efficiency? 



In the first place and probably of more importance than anything else, 

 it is capable of giving a pressure impossible with a hand machine. Any- 

 one who has worked the handle of an old barrel pump hour after hour 

 knows that with its use a pressure of more than 100 pounds is almost out 

 of the question. Our modern gasoline outfits with from two to four 

 leads of hose, will easily maintain a pressure of from 160 to 200 pounds. 



It is probably true that such a high pressure is not necessary in all 

 cases, but it is true that by means of it more thorough and consequently, 

 more effective work can be done in a much shorter time and with much 

 less effort. 



Often the small orchard holder can not afford to pay $400 for a good 

 power machine when he can buy a barrel outfit for $20. The latter can 

 be made to do the work well with a greater amount of time and labor 

 expended. 



There is a tendency in the fruit sections to try to get along with too 

 few machines. There are certain times when spraying must be done 

 immediately if good results are to follow. For example, the period when 

 the first spray for codling moth .must be applied to be effective is never 

 much more than ten days, or from the time when the petals drop until 

 the calyces close. Often one machine will be expected to spray a hundred 

 or more acres during that time. Can it be made to do it and do it well? 

 Let us see:
