mattress factories, etc. Ordinarily the bagging and ties sell for 

 about one-half to 1 cent per pound. Some of the picker waste brings 

 one-half to 2-J cents per pound. Flat strips sell for 60 to TO per cent 

 of the value of middling Upland cotton. Card stripping? are worth 

 TO to 80 per cent of the value of middling, and comber waste from 

 the better grades usually sells at the price of middling Upland cotton. 

 The second column in Table IX shows the waste that would have 

 been removed if the comber had taken out the theoretical amount 

 with the 23 to 25 per cent setting. The third column shows the 

 pounds actually removed. The fourth column shows the difference 

 between these two, while the last column shows the actual value per 

 bale of this difference at 20 cents per pound, the price actually paid 

 for this 11-inch cotton.

Again, the figures shown in the last column are those for raw cotton 

 at 20 cents per pound. However, in order to get the actual value of 

 the difference at this point we must now take into account, as before, 

 the tare, waste on pickers and cards, the invisible loss, and the aver- 

 age actual comber waste of 1T.46 per cent on the 23 to 25 per cent set- 

 ting. These various factors make a total of 34.4T per cent loss when 

 the cotton has passed the comber, so that the actual value of the cot- 

 ton from the comber is not 20 cents, but 26.90 cents per pound. 

 Adding again the labor and overhead charges the cost to the mill of 

 the cotton from the comber will be about 31 cents. Therefore, if the 

 values as shown in the last column of Table IX are calculated on the 

 basis of 31 cents per pound the Durango would be worth, per bale, 

 $5.53; the Columbia, $12.26; the Lewis, $18.36; the Webber No. 1, 

 $3.39 ; the Webber No. 2, $9.14 ; and the Delta, $12.26 more than the 

 commercial calculation on the 23 to 25 per cent setting. 



A comparison of the values given in the last column in Table VIII 

 shows that all the Carolina cotton, if averaged on the 13 to 15 per 

 cent setting is better than the commercial calculation by $3. IT per bale, 

 while the Delta is $1.08 better. This shows a difference of $2.09 per
