HORTICULTURE. 145 



PROBLEMS. 



1. An examination of plans adopted in New York State shows 

 that over 90 per cent of the apple orchards are planted on the square 

 plan ; and the typical distance is 33 x 33 feet. According to this plan, how 

 many trees are there on an acre? On ten acres? 



2. The investigation of orchards in New York State showed that 

 the average income from orchards for four years was as follows: 



1. Trees planted 30x30 $ 96 54 per acre annually. 



2 . Trees planted 33x33 110 02 per acre annually. 



3. Trees planted 35x35 107 28 per acre annually. 



4. Trees planted 40x40 107 32 per acre annually. 



3. According to above results, what would 'be the difference between 

 the income from two orchards, one planted 33x33 and the other 30x30, if 

 each orchard occupied 10 acres? 



(It has been demonstrated by the U. S. Department of Agriculture 

 that trees 30x30 or closer in old. orchards, are too close for profit.) 



4. A fruit grower on the thin hilly sections of Ohio, may plant 

 trees 25x25; on rich ground the distance is often best at 35x35; and on 

 very fertile soil the distance should not be less than 40x40 ft. each way. 

 Find the difference in number of trees in two orchards, of 5 acres each, 

 one planted 25x25 and one planted 40x40 feet each way? 



5. The following table gives the distance for planting generally 

 adopted by fruit growers : 



Standard pears and cherries 20 x 20 feet each way 



Standard plums, apricots, peaches and 



nectarines 18 x 18 feet each way 



Dwarf pears 10x12 feet each way 



Grapes Ro\vs 9 to 10 feet apart 



Plants 7 to 10 feet apart 



Currants and gooseberries 3 to 4 feet apart 



Raspberries and blackberries .3 to 4 by 5 to 7 feet apart 



Strawberries for field culture 1 to 1$ by 3 to 4} apart 



Strawberries for garden culture 1 to 2 feet apart 



Find cost by consulting seed and nursery catalogs. 



NOTE TO TEACHER Give problems to find number of plants per acre. 



The Pleasure and Profit of Fruit Growing. 



Every home in America, where there is sufficient ground 

 about the home should have a fruit garden and if possible, in
