THE IRRIGATION AGE. 



The first aid knot is illustrated in Figures 76-78. 

 It is a very convenient method of fastening a band- 

 age on a wounded finger when a person must do so 

 without assistance. In Figures 76 and 77 a piece 

 of small rope is used so as to better illustrate the 

 method of forming the knot. A piece of small twine 

 or thread may be used in exactly the same way. 



To form the knot, make two round turns over 

 the fingers as shown in Figure 76, and draw the end 

 through these two loops, then take the loop A, lift 

 it up, and place it over on the other side of B, as 

 in Figure 77. The knot is now ready to slip over 

 the bandage as in Figure 78. Simply pulling on the 

 two ends till the right degree of tightness is attained 

 is all that is necessary, as the part A crossing the 

 other parts where it does, holds them in place and 

 no further tying is required. 



The safety bow knot takes but a second longer 

 than the ordinary knot in tying, and if properly 

 tied and pulled taut, will stay as long as desired. 

 The ordinary bow-knot as generally tied in a shoe- 

 string frequently becomes untied at timesvwhen the 

 owner prefers to have it stay tied. The safety 

 feature is added by simply making a double turn 

 with the bows at the finish of the knot instead of a 

 single turp. It will be noticed that this is very 

 similar to the finish of the surgeon's knot illus- 

 trated on a previous page. In Figures 79 and 80 a 

 piece of rope is used instead of a shoe string, be- j 



crotch of a tree or limb without 

 tying a knot. It will hold any 

 strain that the rope will with- 

 stand as long as the rope is kept 

 taut, but may be easily shaken 

 loose when the strain is removed. 

 It is often convenient in cases 

 where it is desirable to use a rope 

 in descending from a tree, or 

 other high place. If fastened with 

 this hitch, the rope may be 

 loosened by simply shaking it 

 vigorously. Figure 82 shows 

 what is sometimes called the 

 double Blackwall hitch. It is 

 a little less likely to slip when 

 used on a big hook. 



cause the method of tying is much easier to show in 

 this way. Figure 79 illustrates the method of tying 

 the ordinary bowknot. Figure 80 shows the loop 

 doubled under again to form the safety feature. 

 This knot may be loosened by pulling the ends of 

 the string the same as the ordinary bowknot, but a 

 harder pull is required. 



The Blackwall hitch, illustrated in Figure 81, is 

 a simple way to fasten a rope to a hook or to the 



GROWING THE BLACK LOCUST IN SOUTH- 

 ERN IDAHO. 

 By Herbert Shearer. 



It is not generally well known that the black 

 locust thrives in southern Idaho. Some one tried 

 it on a high altitude and the impression got out that 

 it is too tender to stand the winters. A few groves, 

 however, have done so well that the tendency now 

 is to plant black locust instead of the poplars, and 

 other soft woods that have heretofore been planted 

 as wind breaks and shade trees. 



Paul S. A. Bickle has five acres in black 

 locust, which were planted in 1907. His trees cost 

 $12.00 per acre, and Mr. Bickle estimates that the 

 planting cost $12.00 per acre. They were set four 

 feet by five feet, and irrigated by furrows between 

 the rows. Mr. Bickle tells me that he could cut 

 this year and sell $50.00 worth of posts from each 

 acre. 



A post contains about seven feet broad meas- 

 ure and is worth twenty cents. They grow again 

 from the stump, so he thinks he can cut fifty dollars' 

 worth of posts per acre each year from now on. In 

 addition to this return he has had considerable pas- 

 ture between the trees. So far he does not consider 

 that the land has been given up to the growth of 

 timber exclusively, because the value of the pasture 

 has gone a long way towards paying interest on 

 the investment. 



H. L. Hollister expects to use a good many 

 black locust trees for wind breaks and for wood lots 

 on his land near Jerome. 



Senator Fred W. Hastings, who has a farm ad- 

 joining the town of Wendell on the north, has a 

 very interesting grove of black locust trees planted 

 four years ago. Senator Hastings has had no trouble 

 from frost and does hot anticipate any, but says he 

 is careful not to irrigate too late in the season, as 

 he is particular to have the new wood well ripened 

 before winter. 



Black locust trees planted two or three rows 

 together will make a very satisfactory windbreak 

 in about three years. Many of the trees will meas- 

 ure five inches through at the stump the fifth year. 

 In fact, it is estimated that the growth will average 

 about an inch a year. 



The black locust in Idaho is free from insects 

 and has proved to be frost-hardy, except in the 

 higher altitudes.
