importance from an economic point of view, 

 as lumber is becoming very scirce. Gov- 

 ernment aid will have to be applied, for 

 there are few i>rivate parties or companie-^ 

 that can wait the long term of years for the 

 returns. The government forest reserves 

 are the proper places for these replanting 

 operations to start. And with the popular 

 interest which is aroused we shall not have 

 to wait many years for this work to begin. 



Second, we shall have to have reservoirs 

 enough to impound all the flood waters 

 which usually go to waste. In many dis- 

 tricts this is almost fully accomplished, and 

 the saving in floods averted is beyond com- 

 putation. 



Third, it has been found that an under- 

 flow exists in nearly all parts, of Eastern 



practiced in California. 

 Houlder, Col. 



Colorado east of 

 the foothills. This 

 is held quite close 

 to the surface by 

 an impervious sub- 

 soil of clay which 

 is as effective as a 

 rubber blanket 

 would be. In most 

 places this water is 

 from 25 to 200 feet 

 down. Where the 

 sub-surface flow is 

 lower than 150 feet 

 it can not be prof- 

 itably i)umped. 

 This sub-surface 

 flow is largely from 

 the irrigation wa- 

 ter which sinks 

 down too far for 

 the plant-roots to 

 use, and so is lost 

 unless caught and 

 pumped back to 

 the surface. Elec- 

 tric power is now 

 so reasonable that 

 hundreds of farm- 

 ers are pumping 

 their under flow 

 back to the sur- 

 face by means of 

 the electric motor. 

 There is one more 

 conserving meth- 

 od that has not yet 

 found its way into 

 Colorado enough 

 to speak of, but is 

 sure to come, and 

 that is the carry- 

 ing of water in 

 closed pipes, sav- 

 ing the seei)age 

 and loss from leak- 

 age which always

 ditches. As water 

 becomes higher in 

 price we shall see 

 the adoption of 

 this, just as it is 



SWEET 



CLOVER AS A NOXIOUS-WEED 

 ERADICATOR. 



Canada Thistle Choked Out. 



BY E. S. HACKER. 



Sweet clover is one of the most valuable 

 plants known to the farmer and bee-keeper 

 alike. To the bee-keeper it is valuable as a 

 honey-plant, for it furnishes pasture for the 

 bees for quite a length of|time, and yields 

 nectar very abundantly. It is a splendid 

 plant for a white-clover locality, as itfpro- 

 longs the honey-flow fully two weeks or
