COSTS OF ACTUAL MARLING LABOURS. 



Total cost of applying marl, per 100 bushels, at the average dis- 

 tance of 1433 yards from pit to field ; or with 25 miles and 

 138 yards, of total daily travel. 



From all these detailed premises the conclusion has been reached 

 that, under the circumstances stated, or others not of greater diffi- 

 culty, the total cost of applying marl is less than 70 cents for the 

 hundred bushels (69.34). The circumstances, and the elements 

 of cost, of course must vary with every locality, and even frequently 

 at the same locality. Nevertheless, the foregoing estimates and 

 results may be applied 'to any other operations, with due allowances 

 for differences ; and thus may be facilitated the calculations of the 

 amounts and the costs of other marling operations. 



From my large experience, not only of the years 1844 and 5, 

 but since to the present time, there can be no doubt of the ability 

 of carrying 1890 Ibs. (18 bushels) of marl as the regular loading 

 of a two mule cart, on nearly level routes, and on firm ground and 

 good roads ; and that the regular and continued daily travel of 

 the carts, from pit to field loaded, and returning empty, may be 

 25 miles and 138 yards each day. Upon these grounds, it will 

 be easy to calculate the cost of marling at any greater or less dis- 

 tances than the average of mine (2867 yards from pit to field and 

 back) in the particularly noted trial in 1844. The transportation 

 is usually the main expense of marling. This, alone, increases 

 with and is in proportion to the distance; the other expenses are 

 not affected by the distance of carriage, but remain in proportion 

 to the quantity of marl carried out, under like circumstances. 

 With the conditions last stated (for 1845, page 204), my expense 

 for carting alone of 100 bushels of marl, in trips to and fro of 

 2867 yards average distance, and making 25 miles and 138 yards 

 of total travel daily, amounted to 39.84 cents. All the other ex- 

 penses of applying the 100 bushels made 29.5 cents. These facts 

 furnish premises upon which to calculate what the total costs would 

 be for any other length of trips, as follows ;
