328 SCHOOL AND HOME GARDENING 



33. At Winthrop College there were 150 school gardens, each 

 9 by 24 feet. What was the acreage in all? 



34. Between these rows of gardens are paths three feet wide 

 (running the long way). The cross paths are two feet wide. Wliat 

 is the total amount of land required for the 150 gardens? 



35. What is the area of all the pathsi in the above tract ? 



36. Gret prices of seeds and calculate the total cost of seeds for 

 a half-acre garden with such crops as indicated in the garden plan, 

 not including the bush fruits and perennial plants. 



37. Calculate the income for each crop as indicated in problems 

 3, 4, 5, and 6. 



38. Calculate the cost of production, allowing $4 per acre for 

 manure or other fertilizer, $3 for plowing and harrowing one acre, 

 $3 for horse cultivation for the season on the half-acre, $10 for 

 planting and hoeing, and $25 for harvesting and marketing. ( Change 

 these estimates, if possible, to suit your locality and season.) 



39. If the crop of potatoes mentioned in problems. 5 and 6 is 

 half lost by attacks of potato beetles, because of not spraying, what 

 would have been the profit from spraying to kill the beetles, at a 

 cost of $1.50 each for three applications? 



40. Tomato plants can be staked and tied up for about 2 cents 

 each. What would have to be the increased returns on one-tenth 

 acre to double this cost, if the plants are at distances 3 by 3 feet? 



41. Water pipes with nozzles 3% feet apart, mounted on posts 

 7 feet above the ground, may be made to irrigate a plot 25 feet on 

 each side, or 50 feet wide. If two such pipes are used how long 

 should they be to irrigate one-half acre? What would they cost at 

 5 cents per foot? 



42. How many nozzles would be required? What would they 

 cost at 5 cents each? 



43. If the posts are placed one rod apart in each line, how many 

 would be required in the two lines? What would they cost at 25 

 cents each? 



44. What will it cost to dig the holes and set the posts, if a 

 laborer can do 25 in one day and he gets $1.25 per day? 



45. What will it cost to drill the holes in the pipe and screw 

 in the nozzles, if a laborer can do one every six minutes, and works 

 ten hours for $1.25? 



46. Allowing $1.25 for valves, $3.50 for strainer unions, $2 for 

 labor not included in the five preceding problems, and $75 for pump 

 and gasoline engine, what is the total cost of the equipment for 

 irrigating one-half acre?
