Board and lodging and free passage there and back to be provided 
by you. 
We have refrained from quotting for the services of an engineer, 
but if desired will revert to the matter. 
Besides the machinery and the steam engines we have also 
quoted for the constructional ironwork. 
All building work would be carried out by you in accordance 
with our plans andat your expense. We cannot undertake this work 
as the sources of labour and material, as well as local conditions are 
unkown to us. 
The belting and woodwork are not included because these parts 
can be moreeasily and cheaply obtained on thespot than if they were 
made here and had to bear the heavy freight costs. 
We trust that our design will meet with your complete approval 
and that you will be thereby induced to place the order with us. 
Awaiting your further favours, and always ready to supply you 
with any further information you may recuire. 
We are, dear Sir, 
Yours faithfully,
