2,000 years most farmers have cultivated 

 only ("i to 8 inches of soil. They have spent 

 millions of dollars adding to these O-inch 

 farms plant foods, such as potash, phos- 

 phorous and lime, that already lay in the 

 subsoil waiting to be made available.

In an L. C. SmitH & Bros. Typewriter the .pot 



on the paper which is to receive the type impression is stationary ;it the instant the type 



hits. The carriage does not bob up and down when the shift i.s made to write capitals. 



Why.> Because the type is shifted — not the carriage. 



The only movement of the carriage is back and forth on its closely adjusted hall bearing 



runways— and this does not take place while the print is being made. There is no lifting 



of the carriage. 



This is one reason why L. C. Smith & Bros, typewriting is free from blurs and every 



letter in the right place. Ask for dcmotislra/ioti.

,^reen; even the best grades cannot be 

 used in this valley. Bordeaux mixture, 

 liowever, does not cause such severe 

 in.jury in the West as it does in the 

 humid Eastern States, but even this 

 mixture must not be used too fre- 

 (luently. Lime-sulphur solution of a 

 strength commonly used with success 

 throughout the East for summer spray- 

 ing cannot be used in the Pajaro Val- 

 ley for .spraying without injuring the 

 foliage. This is true of other soluble 

 sulphids which naturally suggest them- 

 selves as mildew sprays. 



Sometimes as much as 90 per cent of 

 the foliage on trees of susceptible vari- 

 eties in the Pajaro Valley are attacked 

 by this disease. The orchards in this 

 district suffer more from the mildew 

 than do any other large apple-produc- 

 ing districts in the United States. The 

 importance of giving proper attention 

 to control it is increased by the fact 

 that the disease comes back regularly 

 year after year and gradually acquires 

 a stronger foothold if its progress is not 

 checked. The mildew occurs most 

 commonly on the undersides of the 

 leaves. The affected areas are white or 

 grayish, and the term "powdery" very 

 well describes their mealy appearance. 

 The diseased spots may vary in size 

 from a point invisible to the naked eye 

 to patches three-fourths of an inch in 

 diameter, and several of these may be- 

 come established on a single leaf. In 

 a large percentage of cases the entire 

 upper and lower surfaces of the leaf 

 become involved. Mildewed leaves are 

 crinkled and stunted and often very 

 much narrowed, owing to the fact that 

 the growth and expansion of the leaf 

 tissue is checked in the area covered 

 by the fungus. In the Pajaro Valley 

 the disease makes such rapid progress 

 during the spring and summer that by 

 the end of the leaf-forming season it is 

 difficult to find normal, healthy leaves 

 in any unsprayed Yellow Newtown or 

 Yellow Bellflower orchard. The dis- 

 ease attacks the foliage and current 

 year's twigs' growth, but rarely infects 

 young fruit and only occasionally at- 

 tacks a flower-cluster bud. When it 

 does attack a cluster the individual 

 flowers are usually reduced in size and 

 much deformed. 



No varieties of apples grown in the 

 Pajaro Valley are immune from pow- 

 dery mildew, but some are more seri- 

 ously affected than others. The rela- 

 tive susceptibility of dilTerent varieties 

 will probably be found to vary in dif- 

 ferent apple-growing districts, depend- 

 ing, among other factors, upon the 

 effect which the local climatic and 

 other conditions have on the foliage 

 vigor. In general, the varieties that 

 produce strong, vigorous foliage are 

 less suceptible than the more deli- 

 cately growing ones. In this connec- 

 tion it is interesting to note that in the 

 Pajaro Valley the Yellow Newtown, 

 which is one of the most susceptible 

 varieties, can apparently be made much 

 less susceptible if the vigor of the 

 foliage be increased by stiuuilation 

 such as comes from spraying with very 

 finely divided forms of sulphur. \ list
