secured from proper salting will overcome many objections which 

 appear to be well founded in the beginning. 



Naming, numbering, and marking salt grounds. — Salt grounds are 

 sometimes marked by a signboard bearing the name or number, or 

 both. This is of advantage in formulating and following out a writ- 

 ten salting plan. The cost of marking the many salt grounds which 

 should be selected and used, however, would consume more time than 

 is warranted for the present. Further, it is difficult to plan a system 

 of salt grounds so that the site first selected will prove satisfactory 

 in every case. Changes from time to time may be advisable as the 

 system is perfected. There is a possibility, also, that the location of a 

 salt ground may have to be changed occasionally to prevent unwar- 

 ranted injury to the range.

On the other hand, a system of salting places such that a written 

 salting plan can be prepared and followed is essential in securing 

 proper salting without unwarranted supervision. A few important 

 salting places in each set might be marked by a signboard bearing 

 the name and number, or just the number. These would serve as 

 landmarks in describing and finding the other numbers of the series. 

 Perhaps every tenth salt ground of a series might be marked by a 

 signboard. 



Time of salting. — Salting can be taken advantage of in controlling 

 the time a given piece of range is grazed, and the schedule for time 

 of salting should be prepared with this end in view. In the discus- 

 sion of grazing periods it was pointed out that the beginning of 

 growth in the spring is delayed from 7 to 10 days with each 1,000
