FOR PROFIT. 73 



and from their root power, with refraction from the 

 heated soil in summer, the wood becomes riper, and 

 thus they often fruit freely when Standards fail. At 

 the same time a large number can be planted per 

 acre (302 at 12-ft. apart) so that with, say, six or 

 eight varieties, it is very rare even in scarce years 

 that there is a failure. The best varieties are noted, 

 Nos. I to 33 in previous chapter, and when planted 

 in alternate rows for the purpose of perfect cross 

 fertilization, annual crops can be counted upon. We 

 have grand old examples of trees on Paradise in our 

 Nurseries, and their life promises to be quite as 

 prolonged as Apples worked on Crab Stocks. Failure 

 sometimes occurs because the trees are planted too 

 "fleet," exposing the stock to the air, These and 

 Pears on Quince should always have the junction of 

 stock and scion 3 -in. below the surface, otherwise the 

 stock growth is restricted and the growth is checked. 

 The same remarks apply to Pears on the Quince 

 Stocks — both as to fertility, quality, and culture ; for 

 sorts see Chapter VIII.
