 for shellac, this can be done. Sim- 

 ilarly, under cei'taiii conditions, vari- 

 ous other nioditications may be made, 

 although alterations in Nos. 1, 2, a and 

 7 should be made with caution. It may 

 so happen that if al; insect-eaten wood 

 is removed, the tree may be danger- 

 ously weakened; un<ler such conditions 

 the di.seased matter can be removed to 

 solid wood and the cavity fumigated. 

 Other sug,gestions along these lines 

 may be found in the pamphlet issued 

 by the department. 



The department lealizes that this 

 science is comparatively new and that 

 methods in tlie neai- future may be de- 

 veloped that will ijiove far superior to 

 some now in common use. It there- 

 fore invites correspondence eithei- 



from individuals or firms concerning 

 new methods of treatment, and is pre- 

 paied to advise regarding any particu- 

 lar method so far as experimental re- 

 sults will permit. The co-operation of 

 all who are interested is necessary for 

 this work. All interested are urged to 

 write for the new bulletin. 



Fall Plowing 



Fall plowing possesses many advan- 

 tages in the greater part of the agricul- 

 tural area of Washington. 



(1) Fall plowed land left rough will 

 absori) the wintei's precipitation much 

 more completely than a flrm surface. 

 This advantage is very important, ex- 

 cept in some of the regions of heavy 

 rainfall in Western Washington. 



(2) The winter's rain and snow will 

 settle the furrows, shutting out exces- 

 sive air space and restoring capillary 

 connection with the soil beneath. This 

 I)uts the soil in better shape for rapid 

 and extensive root development and 

 greatly lessens the danger of the fur- 

 rows drying out if much manure, stub- 

 ble 01' other refuse has been plowed 

 undei'. This settling of the furrows 

 accomplished by nature is more effec- 

 tive and costs less than the firming of 

 spring plowing done witli coinjjacting 

 tools. 



(3) The weathering of the loosened 

 furrows improves the physical condi- 

 tion of heavy soils and aids in the 

 liberation of latent plant food. The 

 immediate yielding power of a given 

 piece of land is not determined by the 

 amount of plant food actually stored in 

 the soil, but by the amount of ])lant 

 food thai can be made available to the 

 immediate crop. One of the leading 

 purposes of tillage is to encourage the 

 development of available plant food in 

 the soil. 



(1) In the hilly sections land plowed 

 on contour lines in the fall and left 

 rough is less ajit to wash and gully than 

 the same soil left with a linn surface. 

 This is becoming an imijortant consid- 

 eration in the grain belt in most cases. 



(o) Fall plowing economizes time and 

 laboi- by utilizing teams and equipment 

 that would otherwise be idle, and re- 

 lieves the usual congestion of spring 

 work. This usually gives time for bet- 

 ter soil preparation in the spring. In 

 most cases it is probably better not to 

 fall-plow land that is to be summer 

 fallowed, but instead disc the surface. 

 Discing in the fall will give the bene- 

 nts of fall plowing in a minor degree. 

 Summer fallow land is usually apt to 

 become too compact by the spring after 

 seeding if it is plowed the fall before 

 suniiFier fallowing. It is also usually 

 best not to fall-plow a leachy soil in a 

 wet climate. 



In general, however, it is usually de- 

 sirable to fall-plow for spring crops in 

 most parts of Washington, except where 

 the spring seeding is done on summer 

 fallow. We would uige those who have 

 not practiced fall plowing for spring 

 crojjs to give the practice a small trial 

 this fall. Land may be given a deeper 

 jjlowing in fall than in spring with good 

 results. — George Severance, Agricultur- 

 ist, W^a.shington State College. 



New Soil Acidity Test 



What is expected to prove a more 

 positive test for soil acidity than the 

 connnon litmus paper test, and one 

 which, because of the cheap and harm- 

 less chemicals usetl in its operation, 

 will be within the reach of the ordi- 

 nary farmer has been devised by F. 

 Truog, instructor in the department of 

 soils, (".ollege of .\giiiulture of the 

 I'niversity of Wisconsin. 



The new test, it is believed, will be 

 of especial benelit to county repj-esen- 

 tatives and to field agents of the slate 

 soils laboratory, owing to the fact that 

 it is simple to o|)ei'ale and can approxi-
