DRILL BOARD DEVISED AND USED IN THE MUXUiMExNT NURSERY BY W. H. SCHRADER. 

 THE BOARD IS SETTLED IN THE SOIL FOUR TIMES FOR EACH BED COVERED BY A 

 TWELVE-FOOT SHADE FRAME 



soldered in the corners. The top is 

 rohed over a number 12 wire to give 

 strength. For the inside of the basket 

 several thin quilted pads are furnished. 

 These are fastened on vertical wires at 

 one end and the trees are placed in 

 layers between the moistened pads. 

 This provides perfect protection for 

 the lower layers while the upper layer 

 is being used. 



By continued fertilizing the physical 

 properties of the nursery soil have been 

 >o changed that now plants may l)e 

 taken up with more soil clinging to their 

 roots than formerly and by the use of 

 the above described box and basket are 

 kept in excellent condition until planted. 



TRENCHER 



Commercial nurserymen make use of 

 two heavy, wheeled implements known 

 as "trencher" and "firmer" for jxitting 

 in broadleaf tree cuttings. These, of 

 course, are used in broad level fields 

 which arc in a perfect state of tilth. 

 They simply apply the principles of s^il 

 jilanting by the use i)f horse power. 



The first implement opens a continuous 

 slit or trench into which the cuttings 

 are placed and the second follows and 

 packs the soil firmly against them by 

 means of two very heavy cast iron 

 wheels rolling on either side of the 

 row at a slight angle to the vertical. 

 The writer, in an attempt to make use 

 of the principle of the trencher for 

 planting coniferous trees on the Nebras- 

 ka Forest where the steep hillsides make 

 the use of wheeled machinerv practi- 

 cally impossible, devised the implement 

 known as the Mast Forest Trencher. 

 It consists of a heavy \'-shaped shoe 

 fastened on an ordinary steel plow 

 beam and supplied with handles similar 

 to plow handles. The shoe is 24 inches 

 long, ]'? inches deep, and is made \^- 

 shaped by riveting plates of steel to- 

 gether at the bottom and separating 

 ihem .3 inches at the top. These plates 

 are welded and drawn out into a thin 

 sloping edge in front, the lower part 

 of which is widened into a broad nose. 

 The nose draws the shoe into the soil 

 and a small horizontal i)late attached
