REPORTS re EXAMINATION of BATHURST ISLAND. º. Botanic Garden, Palmerston, July 1st, 1910. Sir–I have the honor to report that, in compliance with your instructions, I proceeded to Bathurst Island on the 15th ultimo in the lugger Venture, accompanied by the Government Surveyor (Mr. E. C. Playford) and Constable Miller, to make an examination of the island, which is situated about 50 miles from Palmerston, and is estimated to contain an area of 786 square miles. • * * Owing to light airs and head winds Mr. J. Cooper's camp on Melville Island was not reached until the afternoon of the 17th. It had been arranged that Mr. Cooper, owing to his intimate knowledge of the Melville Island natives, . should form one of the party, and that a number of natives should be picked up here to act as carriers. Unfortunately Mr. Cooper was absent on the mainland, and it was impossible to communicate with him without entailing a delay of four or five days' time. It was therefore decided to endeavour to obtain carriers and push on. About mid-day of the 18th five Melville Island men and three small boys turned up. These were engaged, and a start was made for Bathurst Island. - - - + After a fine run during the night, Bathurst Island was sighted on the 19th, and a landing was made in the afternoon on the north-west coast. The country between that and Roe. Point, situate on Apsley Strait, was then thoroughly examined until the afternoon of the 24th, when the lugger was again boarded. We then beat down the strait and landed at Durham Point at 2 p.m. of the 25th June. From there we traversed the country in a south-westerly direction towards a large salt arm, shown on the chart as existing on the west coast; thence south-easterly to coast, and parallel with the coast, until within four or five miles of the strait, where we rejoined the lugger on the evening of the 28th June, and returned to Palmerston by mid-day of the 29th. & + A* - - Owing to want of time it was impossible to make the examination more detailed or to visit the western side of the island. - - The result of my examination may be briefly set out as follows:— The island on the north and south sides is bounded by sandy beaches with occasional intrusions of mangroves, and numerous little indents and bays make landing easy. - º On the side facing Apsley Strait a heavy growth of mangroves prevails throughout, with occasional bluffs and points jutting out into the strait. At these places there are generally only a few mangrove trees, and consequently easy access to the island. No doubt landings could also be easily formed at the heads of the numerous salt water arms and creeks running into the island. * , The western side of the island was not visited, but apparently the sandy beaches continue there, and the chart shows a very large salt water arm as running into the island from that side. se The country traversed was found to be gently undulating, splendidly drained by numerous creeks, and the soil seen may be generally described as a sandy fertile loam of great depth, well timbered by various species of eucalyptus and with an undergrowth of palms (Livistonia Leichardtii), or wattles. - In the northern part of the island traversed the timber consisted nearly wholly of fine trees of woolly- butt (Eucalyptus miniata), with a heavy undergrowth of fan palms (Livistonio Leichardtii). The latter would not present the slightest difficulty in the bringing of the land under cultivation, and could be very easily “rolled ” down. . - - º w The soil is a deep fertile sandy loam, a natural exposure showing about 10ft. of soil. The quality of the soil is well shown by the luxuriant growth of the timber and undergrowth, and is very consistent, being even good right up to the tops of the few small ranges met with. Ironstone outcrop and gravel was quite conspicuous by its rarity. º * - • * , The country traversed in the lower half of the island, viz., from Durham Point, is not of such consistent quality, nor do I consider the quality of the soil quite as high, though still very good. A natural exposure seen showed a depth of about 15ft. of sgil. The soil is still a sandy loam, but rather light in patches, and occasionally patches of ironstone rubble intervene. - * The country around the ranges also is stony, and unfit for agriculture. The timber growth continues good, but consists principally of stringybark (Eucalyptus tetradonta), with an undergrowth of shrubby wattles of various species. Towards the coast the growth of grass becomes coarser, but instead of being withered up, as it is at this time of the year in the neighborhood of Port Darwin, it is as beautifully green as if in the middle of the wet season, and, though flowered off, presents a mass of beautifully-leaved *; - • * . • p .

I append a list of the plants seen on Bathurst Island. Only a few trees of cypress pine were noticed, and, though the island is very well grassed, it was impossible, owing to the time of the year, to determine any of the grasses.

Sir—I have the honor respectfully to hand you herewith a rough sketch of Bathurst Island, and the following report on my visit of inspection there. Mr. Holtze having made arrangements for a party, consisting of Mounted Constable Millar, himself as leader, myself, and two blackboys, we left Port Darwin in the lugger Venture on the 15th ultimo, and arrived at Cooper's camp, on the eastern portion of Melville Island, on the 17th, where we took on board eight natives for carriers, and then proceeded to the north-western shore of Bathurst Island and landed at a place I, on account of the faulty chart of the island, could not determine and from where we traversed the northern portion first, and afterwards the southern-eastern part. The rock formations seen were very simple, consisting of ferruginous sandstone and iron conglomerate, samples of which I took away for the Government Assayer's determination. With the exception of a little inferior class of iron of low percentage, no metallic formations were met with, and not a trace of silica (quartz). The northern portion of the island is densely timbered with ironbark, woollybutt, stringybark, and undergrowth. The South-eastern has the same growth, only the country there is more open. The soils are light-red loam, light-yellow loam, and light sandy loam, all of good depth and well grassed; the northern part of the island being more fertile than the lower, where areas at higher elevation are covered with broken sandstone, and others with ironstone rubble similar to the mainland. The island is exceptionally watered, numerous large permanent springs being met with, some at an elevation of 150ft. above sea level. No portion of the island traversed reached an altitude of more than 300ft. above sea level, the bulk of it being from high-water to 120ft. * t - There are no signs in the creeks of flood-mark, nor of any surface drainage. All the rainfall, which is heavier than on the mainland, must soak in the deep soil and porous sandstone underlying, from which the springs mentioned take their source. Only in one place was cypress pine trees seen, and were of no size. Very little bird or animal life was seen, and, though it is reported that there are some hundreds of blacks on the island, none were met with. Their fires were noticed, and we came across some of their graves, fenced in with large and most elaborately-carved posts—quite different to any that I have seen before. I have, &c., E. COPLEY PLAYFORD, Chief Warden. His Honor Mr. Justice Mitchell, Government Resident, Palmerston. PLAN |||ſiliſill|| 3 9015 04.133 6275 BATHURST ISLAND (N.
