New Mexico. In this connection, however, it might be 

 well to say that the codlin-moth is generally very much 

 more active and difficult to control than under eastern con- 

 ditions and particularly has this been true of late years. 

 7. Trees in irrigated regions require detailed care every 

 year. A grower in an irrigated district must pay strict 

 attention to his orchard if it is to survive or he is to 

 secure any profit out of it. It is absolutely necessary that 

 it be irrigated and if this highly important operation is 

 neglected for a single season, the orchard is ruined. Fur- 

 thermore, if the irrigating is left to inexperienced hands, 

 the trees are likely to be over-irrigated or under-irrigated 

 to such an extent that they will be injured permanently. 

 Great care also is necessary to see that the water is not 

 allowed to stand on the land or applied at the wrong time. 

 Under eastern conditions, none of these things is necessary, 

 so that orchards which have been neglected not for one 

 year but perhaps several, may often be brought back to 

 profitable bearing. This, however, cannot happen in the 

 Northwest. This partly accounts for the fact that the 

 average northwestern grower is as a rule more thorough 

 and scientific than the average eastern grower. The north- 

 western owner must be thorough or his orchard will not 

 live. The orchard under eastern conditions can usually 

 survive even if somewhat neglected. 



8. In irrigated regions the fruit is usually graded, 

 packed, wrapped and boxed very carefully, while apples 

 under non-irrigated conditions, as a general rule, are not 

 graded or packed as carefully and are seldom wrapped. 

 With the exception of California, fruit in non-irrigated 

 regions is not boxed to any great degree. Fruit is never 

 barreled in irrigated regions. It may be said that in 90
