Notes on the Works of Sowing 
2nd. "When a sowing shall be protected on the north, the lines of defence on 
the south-end will follow the direction of south-west. 
3rd. In the opposite case, where the working-plot is open on the south end, 
the direction of the lines of defence will he to the north-west. 
19. The contractor may in some cases be obliged to deviate from the general 
principles laid down above, but is never to be permitted, for one instant, to 
leave any part of his workyard, when it adjoins the moving sands, with its 
sides exposed and unprotected from the danger of the winds. 
20. The parts at the end of a sowing on the west side which cannot be joined 
to the shore dime, or to a protected Uttey or to a sowing previously completed, 
to be secured by works of defence. 
21. Palisades of planks to be used for these parts, and for the most exposed 
points on the sides of the sowings. The cordons of bush-fences to be kept for 
the foot of the dunes overhanging the lettes of sand. 
22. If tbe movement of the dunes outside the limits of the work rmdertaken 
should threaten the sowings, the contractor must warn the engineer beforehand, 
so that the authorities may take the measures necessary to stop the advance of 
the sands. Any neglect of this rule will exclude him from any right to 
indemnity from loss, under pretext that it arose from causes beyond his 
control. 
23. The contractor only to be paid for the works of defence actually com- 
pleted ; and to bear the expense of any preparatory works which he may 
deem it necessary to set up in the interior of the working-plots to protect 
the sowings while waiting to continue them to the extent fixed in the con- 
tract. He is also answerable for any encroachment or thinner drifts which 
may take place by the movement of the sands within the limits of his under- 
taking. 
4. Special and General Conditions. 
24. The contractor to be responsible for the success of the works, and of 
their maintenance up to the final payment and approval, which is not to take 
place until three years after the last sowings have germinated. 
For the palisades, the wattle and bush-fencing (cordons), the warranting is 
not to commence till three months after the entire finishing of the work, and 
its provisional approval. 
25. The administration not to admit of any excuse, such as the want of 
men, the deamess of seed or provisions, the difiBculty of transport, or tbe 
violent changes of the weather which may have damaged the coverings or 
have destroyed the plants, as, for example, winds, frost, hail, drought, or other 
causes whatever by which the contractor might seek to excuse the failure of 
his sowings. 
26. As the contractor should not make a tender until he has previously 
mastered the substance of all the smaller details, he is to have no grounds for 
claiming indemnity on the plea that the sources of supply for the bnishwood 
have been overrated, or the distance for transport supposed to lie less, or for 
any other reason founded on the supposed errors of the Specification. 
27. Every year a regular statement (jiroch verbal) of the extent of the 
sowings to be drawn up. Tliis statement to contain observations on tbe 
state of the sowings, and to be communicated to the contractor, who must 
either accept it or state his claims for deduction tipon it within ten days. 
28. At the principal angles of the spaces sown in each district, under tbe 
direction of the supermtendent, posts in oak-wood of 4i inches to 6 inches 
in the side, and 62 feet, at the least, in length, to be placed. These posts 
to be imbedded 4 feet in the ground, and to be inscribed on the top with 
a red-hot iron, the year of the execution of the sowing, and consecutive num- 
bers. The part imbedded in the ground to have had previously two coats
