REPORT OF COMMISSIONER OF FISH AND FISHERIES.

After having iu this manner found the sum total of all the distances, 

 the next question will be to find the number of shovelers required. This 

 is found by dividing the sum of these distances by the distance which 

 a laborer can conveniently throw the earth in a horizontal direction, i. 

 e., 3.6 meters. 



It will be better, however, to divide by 3.5, as iu this way a distance 

 will be over, for which, if it is too great to be divided among the 

 shovelers, another shoveler should be engaged, which will be an easy 

 matter. The necessary number of shovelvers, Sh, for removing the earth 

 will be found by the following formula:

2. We liave now to speak of the second method of i)lacing the laborers.

Leaving the fish-pit for the present out of our calculation, tbe same 

 formula will have to be used as in 1, for getting the sum total of all 

 the distances and the required number of shovelers. All we have to 

 ascertain are the distances over which the first and the last squad will 

 have to remove the earth to the dike. 



The length of each of the individual distances has been given here only 

 for the purpose of showing the progression.
