It is assumed, of course, in the estimation of costs, and the 

 consequent calculations of estimated annual profits, that the prin- 

 ciples of good accountancy are followed. 



The resultant value should be considered ; 



The iriaximum price which any man can pay, provided he con- 

 siders the calculated interest rate as a minimum he would accept; 



The minimum price or that which the owner can accept, pro- 

 vided he considers his future estimated incoine to be worth its 

 capitalized value at the calculated interest rate as the minimum. 

 In this connection, the writer begs to repeat from a previous 

 paragraph, this memorandum : "It may often be possible to pur- 

 chase considerably below this maximum valuation or it may be 

 possible to sell considerably above these minimum values, but in 

 each case, the negotiator should be very sure that he is doing so, 

 rather than merely guessing that he is." 



Should this memorandum have shown the need for, and the 

 possibilities for, placing this work on a scientific and mathe- 

 matically correct basis, the writer suggests that, for the sake of 

 the industry, planters and investors in rubber-planting enter- 

 prises arrange to have the problem investigated by some one in 

 whose judgment they have confidence, thereby discovering what- 

 ever faults in logic there may be in this suggested system, and 

 evolving a better one. » 



Carton- Making In the Rubber Factory. 



MODERN' merchandising methods exact from manufactur- 

 ers not only goods of proper and standard quality, but 

 goods so packed that they can be conveniently stored 

 and kept in good condition without deterioration until sold, and 

 can then be delivered to the consumer in attractive form. There- 

 fore, in place of bulk shipments, in bags, boxes, or barrels, many 

 lines are shipped in cartons, big and little, of which millions are 

 used in rubber goods production. 



and a convenience to the customer in carrying home the purchase. 

 To meet this modern requirement of the trade the progressive 

 rubber manufacturer has added to his plant a cotnplete paper-box 

 factory, and few large plants are without them. 

 HOW CARTONS ARE MADE. 

 The making of a paste-board box is far from a simple opera- 

 tion, although machinery has been so perfected that many of the 

 processes arc practically automatic, while others are so simpli- 



Take rubber shoes as an example. Years ago they were shipped 

 in cases, the pairs simply tied together and packed in bulk. To- 

 day they are delivered in single-pair cartons, a boon to the re- 

 tailer in placing the goods in stock, a saving of time in selling. 



ried that no marked cxpertness is required. The stock, or box- 

 board, for making cartons comes in sheets of the proper size to 

 save any waste from trimming. The first operation is to score 

 these sheets where they are to be bent, and to cut them apart, of
