Calculating then, in order to be within the mark, that the macadamized roads afford daily two loads of dirt per mile, and reckoning the great macadamized streets at 100 miles in length, we have the following results:—
Quantity of Street-Refuse collected from the more frequented macadamized Thoroughfares.
| Loads. | ||
| 100 miles, | 2 loads per day | 200 |
| „ | Weekly amount | 1,200 |
| „ | Yearly amount | 62,400 |
Proportion of “Mac” in the above.
| 100 miles, | 1 load per day | 100 |
| „ | Weekly | 600 |
| „ | Yearly | 31,200 |
To this amount must be added the quantity supplied by the more distant and less frequented roads situate within the precincts of the Metropolis Proper. These I will estimate at one-eighth less than that of the roads of greater traffic. Some of the more quiet thoroughfares, I should add, are not scavenged more than once a week, and some less frequently; but on some there is considerable traffic.
Quantity of Street-Refuse collected from the less frequented macadamized Thoroughfares.
| Loads. | ||
| 1100 miles, | ¼ load per day | 275 |
| „ | Weekly | 1,650 |
| „ | Yearly | 85,800 |
The proportion of mac to the gross dirt collected is greater in the more distant roads than what I have already described, but to be safe I will adopt the same ratio.
