In conclusion I would take this opportunity of acknowledging the great assistance I have received from the Acting Assistant Surveyor General (Mr. CoOPER) and from Lieut.-Colonel CHAMPERNOWNE, R.E., during an exceptional crisis, the difficulty of which was increased by my recent arrival in the Colony, and consequent inexperience of the localities, and the departmental organization. With hardly an exception the officials on whom has devolved the superintendence of operations have exerted themselves in a satisfactory manner, and in one case leave already granted was voluntarily ven up with a view to assisting the Department during the emergency. Some of the Overseers have worked overtime, and suffered from exposure to excessive heat and damp, and there is reason to fear that Mr. BAYNE'S end may have been accelerated by the same cause.
I propose advanced to recommend special cases to the favourable notice of Government.
when operations are further
I have the honour to be.

Note A page 3.---Since writing the above I find that Chambers' Encyclopedia (ed: 1882) and the Encyclopedia Britannica (ed. 1881) state, that at Joyeuse (France) 31.17 inches fell in 22 hours, at Geneva (Chambers says Genoa) 30 inches in 24 hours, at Gibraltar 33 inches in 26 hours, on the hills above Bombay 24 inches in one night, and on the Khasia hills (Assam) 30 inches on each of five successive days. These falls if correctly reported exceed that registered here, but as no details are given, nor authorities quoted, I hesitate to accept these statements without further evidence.

PUBLIC WORKS' DEPARTMENT,
23rd June, 1889.
I have the honour to forward you the following report on the damage done to the Water-works by the storm of the 29th and 30th of May last.
Danage.
The Albany Service Reservoir.—Between the hours of 11 and 12 A.M., on the 29th the 16-foot culvert passing underneath the reservoir became blocked at its upper or southern end this caused a heading up of the waters above the reservoir which must have reached from the marks on the slopes some 20 feet above the coping level something then appears to have given way as there are evident signs of a sudden rush of water, the water rushing through the reservoir entered the nearer filter bed lifting some of the sand and depositing it on the concrete margin some 4 feet above.
The culvert being blocked that waters of the Albany Nallah continued to flow into the reservoir carrying with them some 2,000 cube yards of debris and overtopping the dam on the northern side flowed down the earthen slope carrying it away together with the parapet walls of the Bowen Road bridge, the wing walls of the culvert outlet and a short length of the 10-inch main in Garden Road.
The Tytam Conduit.--The conduit was broken and carried away in three places, viz.:---
1st near No. 12 bridge immediately south of the southern end of the Race Course.
2nd at No. 23 bridge south of the Public Cemetery.
3rd at No. 27 bridge south of the Indian Cemetery in all making a total length of 357 feet.
