sections, the engineers are to take care that their assistants 

 proceed^ in all cases, so as to cross and correct each other. 

 The engineers are to be responsible for the correctness o£ 

 the whole. 



" 15. The main drains are generally to be laid down so 

 as to allow the collateral drains communicating with them, 

 to embrace the greatest extent of surface the nature of the 

 bog will admit of: but where the inequalities of level in it* 

 surface, or the outlets of discharge for the waters, present 

 a. choice of plans for its drainage, so as to induce any doubt 

 in the mind of the engineer which plan mav be most eli- 

 gible, he is to submit the different plans to the commisf 

 sioners. 



if 16. The engineers are to accompany the maps with 

 written reports, containing generally whatever occurs to 

 them on the subject of the drainage of the districts assigned 

 to them, and particularly specifying, 



* c 17. The probable expense of such drains, roads, ca- 

 nals, locks, and other works, as they recommend. 



W 18. The names of the proprietors who claim any right 

 or interest in the bogs, and to what extent, and in what 

 proportions, as far as they can learn. 



" 19. Whether any, and what tracts of bog in their di- 



, stricts have already been reclaimed, and what have been the 



manures used, and the modes pursued, in their amelioration,, 



and what is the nature and the state of the crops which 



they actually produce. 



^ 20. The probable value of the land when reclaimed, 

 and the mode of culture which maybe the best adapted for 

 it, particularly distinguishing those parts that may be best 

 suited for planting. 



* f 21. Where any of the bogs proposed to be drained are 

 at present used for the supply of fuel, the engineer is to re- 

 port how far the quantity and quality of the fuel is likely tq 

 be injured or improved by the works which he recommends. 



" 22. Where the wetness of the bog appears to be occa- 

 sioned by a lake on a higher level, the engineer is to report 

 on the practicability and means of draining the lake; and 

 also on the difference of levels in summer and winter of all 

 rivers and lakes connected with the bogs. 



" 23. Where the botlqm of the nog is lower than the 

 river into which it would be convenient to discharge the 

 waters of the drains, the engineer is to report on the prac- 

 ticability of lowering the river sufficiently to receive them. 



" 24. As in many instances the levels may not admit of 

 the bogs being drained in the usual planner, in such cases
