An addendum publication came after his death: <\/p>\n\n\n\n
http:\/\/www.dowsing-research.net\/dowsing\/articles\/Tabraham-solar_energy_and_dowsing_an_ddendum.pdf<\/a><\/p>\n\n\n\n and a talk about his work by Chris Burgess in 1989 and recorded in the BSD Journal: <\/p>\n\n\n\n http:\/\/www.dowsing-research.net\/blog_extracts\/BSD_No229_1990_p117.pdf<\/a><\/p>\n\n\n\n The links above give a more than full account, but\nhere is a very brief over view. <\/p>\n\n\n\n The research information has been extracted from the\nvery informative private publication entitled “Solar Energy and\nDowsing” by A.P. Tabraham, Isles of Scilly 1982. Tabraham was an\nenthusiastic horticultural researcher who was intrigued by the early flowering\nof the narcissus,<\/p>\n\n\n\n The Scillonian farmers who raised these narcissi,\nneeded them to flower before Christmas in order to receive higher premiums\nduring the Christmas market period. This required special treatment of the\nplanted bulbs. The chosen method was to loosely spread straw over the planted\nground at mid-summer and set it alight. This brought the bulbs through the\nground 2-3 weeks sooner than bulbs which had not been treated in this way, the\nlatter finally flowered in the early new year. The origin of the practice was\nunknown, as was the mechanism. It was applied for maybe 50 years until it\nbecame uneconomic. <\/p>\n\n\n\n While investigating other approaches, it seems that\nquite fortuitously, dowsing might provide at least some answers, if not a\nsolution. A series of trials were\nperformed in which propane fires were used to heat the ground, in place of the\nstraw and ground thermometers used to compare the temp of the treated ground\nwith the untreated ground. This proved effective and more economic. Treatments\nwere applied at fortnightly intervals, the more treatments applied, the greater\nthe temperature difference, with a change of approx. 2\u00b0F per treatment (up to 3\ntreatments), which persisted over the following year. The bulbs in the warmer ground duly flowered\nearlier. Now it was discovered that a dowser could clearly identify the burnt\nregions, even 6 months after the burning had been applied and furthermore, the\nbulbs showed a dowsing reaction. <\/p>\n\n\n\n Later, it seems that quite by accident, the\ntemperature rise could actually be caused<\/em>\nby dowsing. But they discovered that ferrous objects could remove the effect,\nthe greater the mass of metal involved, the faster the effect was removed.\nThere was also the observation that despite different farmers using the same novel\nburning technique, it tended to fail for the \u201ctidiest\u201d farmers, where-as less\ntidy farmers got excellent results. This effect they put down to the fact that\ntidier farmers would tend to plough the ground after burning to re-ridge the\nfields. The steel plough had removed the effect.<\/p>\n\n\n\n They searched the dowsing literature to find a novel\nway of applying the dowsing effect without using any burning effect. They\nconcluded with the following simple technique. Simply trace out a pentagon\n(regular or irregular did not matter). This could be done by tracing with a\nstick on the ground, or by marking five points on the ground to form the\noutline of a pentagon, while walking around the field. It was not necessary to\nhave any real physical line marking out the whole pentagon. The essential thing\nwas that the first point must be touched again after walking around the\nperimeter, to compete the pentagon, absolutely no gap at all was allowed, otherwise\nthe dowsing effect was lost. If done correctly, the dowsing effect was created\nimmediately, over the entire area within the pentagon and created a temperature\nrise of 2\u00b0F, (the same as, or slightly better than, the burning over process).\nIf two additional pentagons were added, at fortnightly intervals, the\ntemperature rise was 3-4\u00b0F, and for three, 5-6\u00b0F, depending on the ambient heat\n(see later), but adding additional pentagons made no significant difference.<\/p>\n\n\n\n They had devised a dowsing solution, which was more\neconomic and effective than the burning over method and one which could be\nadapted to any area. It could also be used on other crops. For example, the\nincrease in ground temperature using three pentagons had decreased the germination\nof Freesia seed from four weeks to two. Winter broccoli, sweet corn and early potatoes\nwere also found to benefit.<\/p>\n\n\n\n There were some additional intriguing observations.\nThey discovered that the effect within the pentagoned areas tended to move\nsouth by approximately 6-9 feet per year. This movement mainly took place with\nthe ground was full of water in December and January. Another effect was that\nanything that had been exposed to the \u201cdowsing effect\u201d within the pentagon (or\nby burning over) appeared to \u201cconnect\u201d with any available heat source (above\nambient). The connection could be identified by dowsing and along this \u201cflowed\u201d\nheat to the object. So plants outside appeared to connect with the atmosphere\ndirectly above them. Or if indoors, they might connect to an electric file.\nGlass or plastic did not stop this connection, but thin paper did. The temp\nrise per days was also found to be linked to the number of hours of sunshine\nthat day, but rises were still observed in the absence of direct sunlight.<\/p>\n\n\n\n Tabraham published his data in the first publication. This is best reviewed as graphs.<\/p>\n\n\n\n Above is data from 1979. It compares the average maximum daily temperature, averaged over each month, for ground which had been burnt over three times (red line), compared with ground which had no treatment (blue line). \u00a0A consistent elevation of temperature is observed, with the difference increasing towards mid-summer.<\/p>\n\n\n\n Above is the data taken in1980, after the pentagon treatment had been introduced. It compares the average maximum daily temperature, averaged over each month, for ground which had been burnt over three times (red line), ground which had been treated with three pentagons (black line) and ground which had no treatment (blue line).\u00a0 The pentagon treatment produced a slightly elevated warming effect.<\/p>\n\n\n\n Since the publication of the work, other members of\nthe BSD have taken interest. <\/p>\n\n\n\n In this article the author adds some additional\ninformation obtain directly from communication with Tabraham. The latter\nasserts: that it is in fact not necessary to \u201cwalk\u201d the perimeter of the\npentagon, the creator can simply rotate themselves making five points as they\ndo; the pentagon can be as grossly irregular as necessary; the effect can be\napplied to the warming of buildings. <\/p>\n\n\n\n See the correspondence section, a letter from a Philip.
