On June 12, 1909, Major Charles Campbell (1), hosted a demonstration of the use of gelignite to remove trees at his property, Amesfield Park, in Mornington. Amesfield Park, was originally called Manyung and owned by Richard Grice (2) and was located at the 31-mile post on the Melbourne to Sorrento Road. (3). Major Campbell had purchased the 288 acre property six months previously, in December 1908, for £5,000. (4) He invited his neighbours and a number of officials, including Carlo Catani, to this demonstration.
It was an impressive attendance list and Carlo was in the company of Mr Reid, Surveyor General; Mr Crooke, Forestry Department; Dr. Cherry and Mr Kenyon, Agricultural Department; Mr. Barber, Victorian Railways; Mr W. H. Irvine, M.H.R.; Mr Livingston, M.L.A.; Mr. R. G. Fincham, National bank manager; Colonel Stanley, Victorian commandant; Mr. Aitken and Mr. Drake from Dalgety and Co.; Mr W.F. Weigall, Brighton councillor; Mr. J.H. Taylor, the town clerk of Brighton and Mr James Minifie from the Millers' Association. These guests were conveyed from the Frankston station to the scene of operations by cabs and drags, Mr J. Millard having been entrusted with the "transportation" arrangements. (5)
The Mornington and Dromana Standard of June 19, 1909 explained why Major Campbell decided to use gelignite - Since, purchasing the well-known property, "Amesfield Park," some few months back, Major Campbell has spent considerable time and capital in removing a great many of the thickly studded trees on the estate, erecting wire netting, installing windmills, etc., and in numerous ways going in for big improvements. The modern method of blasting has been chosen to remove the trees, and, in conjunction with Messrs Dalgety and Co., (as agents for Nobel Glasgow high explosives) the squire of Amesfield Park gave a demonstration on a large and effective scale. (6)
The paper continued their report with -The object of the demonstration was to show how easily and cheaply trees could be grubbed by the use of gelignite, exploded by electricity. Mr R Sprague (of Dalgety and Co.) and Major Campbell superintended operations, and the agents were also represented by Messrs Allan and Dorecket. The first "blow up" was a "double event," two trees being removed by connecting the charges by wires, which were attached to the main cable and thence to the battery. When all was ready the crowd retired to a safe distance 150 yards away, and there was much speculation as to the result. Many were certain that the effect would be to merely shift the tree, but do no further damage to the butt. The signal to "Let her go" was given, the handle on the battery raised and lowered, and in an instant there was a terrific explosion. A shower of earth and chips shot into the air, and the trees heeled over and crashed to the ground. An examination of the result showed that the butt had been lifted clean out of the ground and shattered in pieces, and the trunk was opened up in numerous pieces. Two other trees were blasted out together, and three more were removed singly. The manner in which each tree was blown out of the ground was highly satisfactory, and the method is a vast improvement on the old style of grubbing by hand. The seven trees were treated with varying quantities of the explosive, and the cost would average about 3/6 per tree. The agents claim that trees can be removed by the Nobel-Glasgow method at from 50 per cent to 80 per cent cheaper than by hand labour. (7)
There were some finer details provided, in case you are interested in removing trees and have some sticks of gelignite lying around; even though apparently the sale of gelignite is now highly regulated and highly restricted -
In blasting trees or stumps, the first thing done is to find with a crowbar the best place between the roots to get under the body of the stump. If the tree is not too large, an ordinary charge, well situated and carefully tamped, will take it out, but if the stump is large and deep in the ground the hole must be larger than can be made with the crowbar, and charges must be carefully distributed in the best possible situation so as to get the best results. The operator digs down by the side of the stump, and then makes horizontal holes under the bottom of the stump as near to the centre as possible, disturbing the natural earth as little as possible. The charges are placed close to the wood; then are put in the primers and tamp. After putting the charges and detonators in, a little wet clay or dirt is placed at the bottom of the holes and in contact with the stump, thus filling up the entire opening. If the charges are not well under the stump, a small dam is made and filled with water. Wherever the charges are they must be well supported with water, mud, damp clay, or some other compact and weighty material. (8)
At the conclusion of the demonstration at large number of the visitors were the recipients of Major Campbell's hospitality, and the opportunity was taken by Mr Dorecket (of Dalgety and Co.) to thank Major and Mrs Campbell for their kindness, and to express the pleasure the visitors derived from the trip. The health of the host and hostess was drunk enthusiastically. Major Campbell acknowledged the sentiment, and expressed himself as pleased that they had found the demonstration interesting. He would always be happy to show anyone the details of the method, and if they were much interested they could bore the hole and fire the charge themselves. (Laughter and applause). The visitors returned to Melbourne by the evening train. (9)
