toward the needful, to be at your service. I have, agreeably 

 with your letter this day, desired Capt. Thomas Trevarthen to 

 hold himself in readiness for London about the end of this 

 month. I have not yet seen Bull. I wish you to write me if I 

 am to give him notice also to hold himself in readiness for 

 town. I fear that those two persons will not be sufficient to 

 conduct the work with speed, especially if Capt* Trevarthen 

 should be unwell ; he is a good miner and pitman, and could 

 assist in fixing the engines. Bull can only act as an assistant 

 to an engineer, therefore neither of them can take the sole 

 direction of the work. 



" There will be those four large boilers to be put together on 

 the spot, which neither of those persons know but little about. 

 I think it would take a great charge and care from your mind 

 to have a third person with you that could go through the 

 whole of the undertaking, especially as the distance from 

 England is so great. This undertaking of such immense mag- 

 nitude and value ought not to depend solely on your own 

 health, as neither of the other two could get on without your 

 assistance in laying down and planning the outline of the whole 

 of the work belonging to the machinery. If any one of the 

 parts should be lost or broken, it would require some ability 

 in that country to contrive a substitute. The expense of a third 

 able man might prevent much loss of time and difficulty, and 

 would not be an object in a business of such a scale as you have 

 commenced with. 



" I recommend a third person, that you might count on a 

 speedy and effectual start. Even in this kingdom, where 

 machinery is so well understood, I have known several good 

 undertakings fail, from not employing at first an experienced 

 engineer to conduct the work ; which I am doubtful would be 

 the case at Pascoe, if you were not able to attend yourself to the 

 erection, and do not take a person with you for that purpose. 

 I beg your pardon for thus attempting to recommend to you a 

 third person to go out ; but I think a work of this magnitude, 

 where expedition is important, ought not to rest on the health 

 of one man, especially under a changeable climate. Please to 

 consult your friends, and give me your opinion on it in your next.
