Manchester, 26 June 1867 

Dear Moor, 

‘Pursuant to mine faithfully of yesterday’, two half five-pound- 
notes enclosed, whose 2nd halves will follow by Ist post early 
tomorrow morning and thus be in your possession tomorrow 
evening. 

With regard to the production of surplus-value, another point: 
the manufacturer, and with him the vulgar economist, will 
immediately interject: if the capitalist only pays the worker the 
price of 6 hours for his 12 hours’ labour, no surplus-value can be 
produced, since in that case each hour of the factory worker’s 
labour counts only='/, an hour’s labour,=the amount which has 
been paid for, and only that value can be embodied in the value of 
the labour product. Whereupon there will follow the usual 
formula by way of example: so much for raw materials, so much 
for wear and tear, so much for wages (wages actually paid per 
hour’s actual product), etc. Atrociously superficial though this 
argument may be, however much it may equate exchange-value 

4 See this volume, pp. 382-83 and 385. 

with price, and value of labour with labour-wage, and absurd 
though its premiss may be that if for one hour’s labour only half 
an hour is paid, then only "ly hour’s worth goes into the value, I 
do, nevertheless, find it surprising that you have not already taken 
it into account, for you will most certainly be immediately 
confronted with this objection, and it is better to anticipate it. 
Perhaps you return to it in the following sheets. 

You must supply me with an address in London to which I can 
have the £100 sent next week. I am thinking of taking Lizzie’ via 
Grimsby to Hamburg, Schleswig, Copenhagen, etc., one week 
from now, and will probably be away for 4 weeks.**? I shall 
therefore have to get our cashier to send the money there on 
Thursday or Friday, for which purpose I need a neutral address, if 
possible commercial. You must therefore consider whom you would 
prefer for this purpose, and let me know at once. 

When I have sent Lizzie back to Grimsby from Hamburg, I shall 
also go on to visit Meissner and Kugelmann, and then travel to the 
Rhine. 

Kindest regards. 

Your 
F. E.
