336 CITRUS FRUITS AND THEIR CULTURE. 



where it is impossible to get a perfect ridge. These should 

 be looked up and fixed with a shovel. The jump scraper 

 will not entirely close up a check; it generally requires 

 a shovelful or two to complete it. It is usual after the 

 water is turned down one row to fix up the next one, 

 but it is an excellent plan to have a few rows ahead, for 

 there come times when breaks occur and there is not 

 time to make the necessary repairs, and when water once 

 gets the start there is apt to be much trouble and hard 

 work before it can be put under control, besides doing 

 poor work. 



"After the ground is dry enough to work, the ridges 

 are split with a listing plow or a furrower attached to 

 a cultivator. Then the ground should be run over with 

 a harrow, setting the teeth to go well in, so as to pulverize 

 the surface thoroughly. By using the harrow the ground 

 can be worked about one day earlier than with the cul- 

 tivator, and it also prevents the ground from baking till 

 such times as it can be worked with the latter implement, 

 besides doing far better work than with the cultivator 

 alone, especially when there is much land to go over, as 

 some of it is certain to get too dry before it can be 

 reached, and then it will not pulverize well. All trees 

 should be worked around by hand with either a fork 

 or a hoe as soon after irrigation as the ground becomes 

 dry enough and before it becomes hard."
