  1. Here's one I've just figured out... For most of my earlier years in the industry, the National Beekeepers' Assn had admin, accounting, and Executive Secretary services provided by the Pork Industry Board. For my first conference, 1975, Graham Beard was the Exec Secy, followed by David Dobson, and then Steuart Goodman. All up, the NBA worked with the Pork Board for about 20 years... Whenever anyone would ask "Why does the Pork Industry Board" do the admin stuff for the NBA, I had always assumed it was just some other primary producer body who saw the chance to take on an outside contract... But I think I've figured it now. There was already a long standing connection for the PIB to the honey industry! Graham Beard was the connector. In his younger days, Beard qualified in his early life as a cheesemaker ("Blessed are the cheesemakers!"). By the late 1940s, he was working for Marketing Dept (in earlier years, known as the Internal Marketing Division), and served as one of the government representatives on the Honey Marketing Committee. ANYWAY... When the Honey Marketing Authority came into being in 1953/1954, with the Govt clearly signalling that it no longer wanted hands-on involvement in honey marketing, civil servants such as Graham Beard went often to something similar to what they were already doing, with with an industry authority, or a board, or some such. A.C. Bridle, the chairman of the Honey Marketing Committee, for instance, went to work with poultry marketing. Beard went to work as the superintendent and chief technical officer for the Pig Producers' Council, which later became the Pork Industry Board. From 1953 to 1974, over the next 21 years, he worked for the Pork Industry Board. And then, in late 1974, the Pork Industry Board took on the NZ Beekeeper's Association, after the previous Executive Secretary gave notice. Graham Beard must still have had some friends and interests in the beekeeping industry! And a year or so later, Beard ended as the NBA's Executive Secretary (retired?) and David Dobson, of the PIB, took over. And then in 1983 or so Steuart Goodman became the Executive Secretary, to be followed by Ron Rowe, Harry Brown, Tim Leslie and ultimately oblivion for the NBA...
  2. Barely more than a cup or two! When the water level rises in the tubing, it is exerting a force into the wine bag equal to the column of water - not the column of water in the tube, but the imaginary column of water of the same size as the wine bag. So in the case I described, with 9.7 mm water rise in the tube equal to 1kg of weight, if you were weighing a 160kg hive, the water would be 1.6m up the small tube. Admittedly, the models I made back then were not working with that weight - I was designing mostly for something more like half of that - I think I had the scale marked up to 100kg. When you pour the cup of water into the tube, the hive lifts a bit and you can steady it with your hand as it sort of floats on the thin layer of water in the wine bag. If you keep pouring water into the tube, the hive will continue to rise, this will distort its overall 'footprint' (h x w), and make the measurement inaccurate. The most amazing feeling was to stand on the platform yourself while pouring a cup of water down the tube - and feeling it lift you up! Sometime after I did this, I saw a Kiwi designed scale for weighing cattle. It was basically a platform with 4 tyres tubes under it, with valves disabled and tubing between them. Put the cattle on top, pour water until the platform rises, and read the weight on the vertical scale. It was homegrown Kiwi No. 8 wire at its finest, and for a long time I would point at it and claim discovery of the principle!
  3. Weighing beehives ----------------- Some years ago I asked an engineering friend how *he* would weigh a beehive. I expected some sort of tripod lifting arrangement with scale and lever. Instead, he thought about 10 seconds and said "Using a plastic wine bag!". Took him the best part of an hour to explain it to me and convince me it would work. OK, here goes: cheapish wine in NZ comes in 3 or 4 liter cardboard 'casks', with plastic bag with valve out the side. The bags, once empty (ahem...) are in fact flat in construction - find one that is pretty big. Small bag means greater accuracy, but harder to measure (hence less accurate, if you see what I mean). Best I ever made was with a commercial sized bag that was almost the same size as the inside of a bee box. Build the floor arrangement. Basically, a flat base with a telescoping lid that fits over it. Hole cut in base to accommodate the valve arrangement of the bag. Take out the 'guts' of the valve, and glue 10mm diameter plastic tube about 800mm long into it. I added a 20mm x 50mm piece of timber, fixed to the telescoping lid thing with a hinge, to support the plastic tube up the side of where the hive will sit. Fit it all together, put it under a hive. Now, here's the part I couldn't really figure: how much water would you have to pour into the tube in order to lift the hive off the base? Hardly any! After only a bit, water starts to 'back up' the tube to a certain height, then doesn't come up any further! If you keep pouring water, the hive will lift higher, but the distance from bottom of hive to top of water in the plastic tube remains constant. The proper name for this thing is a manometer. If you can't get it from this description, go to a good engineering book to get the concept. By pouring only a little bit of water into the tube, the telescoping lid thing 'lifts' off the base, and the hive is floating on a waterbed type thing. The height of the column of water can be converted into the weight of the hive! The height of water is the 'head'. Imagine a column of water the same size as the plastic bag, and as tall as the head. The weight of that water would be equal to the weight of the hive. So you can calibrate a scale up beside the plastic tube to give hive weight. Weight of hive (gm) = Area of bag (cm2) x Height of water in column (cm) x 1 gm/cm3 (weight of cubic cm of water). For the bag size I used (the only variable), it worked out that each kg of hive weight equated to 9.7mm of water height in the column. It meant you could go some pretty accurate weighing, but the cost of the thing was just about nothing. You *might* want help drinking all the wine... scale.bmp

  5. In the early 1950s, a sort of black-mildew-blight was found on the manuka plants in South Canterbury. Farmers (remember Rabbit Calicivirus?) quickly began to spread it. Reading between the lines, I think the beekeeping community was somewhat split between "Don't kill our significant honey producer!" and "Maybe those hillsides could be clover, too!" over the issue. I haven't come across many unambiguous statements of industry position...
  6. There is one part of me that doesn't much care who the bkpr is. If the colonies are within the realm of 'abandoned or neglected' (however that would need to be objectively defined...) I would be pleased if they were (1) immediately destroyed if any AFB at all is found (2) go through the process - probably must notify the land occupier, notice under lid, perhaps even newspaper notice? - to end up maybe 30 days later and then destroy the hives. I guess if I think about it long enough, the only reason I have for wanting to identify the bkpr is to charge back for the privilege of removing these hives from the NZ situation, since the bkpr so obviously didn't/can't/won't. But generally, given the situation that preceded the 'abandonment/neglect' of the hives, no money might be forthcoming anyway!
  7. I was meaning to say that by about 1950, the Dept of Agriculture had stopped allowing the 'shook swarming' method. The reduction in AFB overall, and an industry-wide interest in dealing appropriately with AFB led to calls such as this to reduce the risks that are out there...
  8. Up until about 1950, NZ beekeepers continued to try out 'remedies' for AFB... The methods almost always involved shaking hives off the frames, sometimes multiple times, to try to use up the last of their stores. Equipment was variously scorched, boiled and disinfected, using the methods and beliefs that were common. It wasn't until about 1950 that (1) 'shook swarming', shaking bees off the combs to treat for AFB and (2) a serious attempt to reduce the risk created by abandoned or neglected apiaries. Even with the calls by the industry at the time, the Dept of Agriculture was loathe to move too much in that direction, probably expecting a serious backlash should they make a mistake. Now? I'm guessing there would be a massively more complex process needed to get rid of 'abandoned or neglected' apiaries... But it still should be happening... Here is an unambiguous request by the industry in 1953, by way of a remit to the NBA conference of that year.
  9. This comes from 1954. I think there are photos of both beekeepers in subsequent beekeeping magazines...
  10. James, I think that rata, a good smoothly granulated rata, is one of the finest honeys in the world. While I might personally think of it as priceless, I do hope you get the price you want...
  11. Here are notes I made re: observations hives some time back: Observation hives... I've used a variety of observation hives, including a 1 frame 'portable', a 2 frame not quite so portable and a 4 frame vertical. And I agree with Kerry Clark - the 4 frame was without doubt the best for a permanent location. The 2 framer I only ever used as temporary - run out and grab a few frames, one with honey, one with brood. Find the marked queen to put on it. And brace it well in the car (it was perspex...). One design (Russian?) that always intrigued me had one or two vertical frames (one frame wide, that is), then a strip of queen excluder, then, effectively, a 4 frame nuc fitted on top. The 4 frame area was closed in (not glass) and acted as a reservoir for bees/honey that allowed the unit to be more permanent. Two choices for how you fit the glass/perspex - 'onto' the surface (using clips, called 'mirror clips', I think, to fix the glass/perspex against the surface). Or sliding the glass/perspex into a groove from the top of the observation hive (only really possible with perspex). Latter gives less air leakage around the edges - I found the bees didn't care for that (lots standing facing the draught at the edges). Make SURE you have adequate means of dealing with condensation - build in HEAPS of mesh, etc, even if you have to keep it covered. But I found no trouble with 25mm (1in) square of mesh at top and bottom of hive. Especially just after installing, you'll be amazed at the moisture given off. Perspex tended to craze after several years, not being as sparkly clean as when first made. Glass is easier to write on - its neat to circle eggs, and date them, watching the development. If for a permanent location, you can have heaps of fun designing entrance ways that allow you to 'draft' individual bees into side chamber, where you could, say, mark them or remove pollen, etc. And you can by having a wide entrance, arrange to have incoming bees going down one side and outgoing down another. For a unit that you'll be moving a lot, or if it will be worked regularly, work out a way of easily closing off the entrance and being able to take the whole unit outside - much better than trying to do bee work inside a classroom, for instance. Design some sort of feeder system, too, for a permanent unit - they'll need a lot of babying along in most locations. You may need to top them up with bees/brood. And in a good season, they'll be able to generate more swarms than you'd think possible! REFERENCES Stevenson, Lt H R. 1985. Establish an observation hive and promote beekeeping! Amer Bee Journal.

  12. Sadly, in N.Z., I think it is simply that there has been little effort to preserve our beekeeping history. The industry has just never been large or important enough for anyone to focus on ensuring the continued availability of the old books. After all, "Everything is on the Internet"... And for sure, if you're going to read these old materials, you need to be clearly aware of the *current* conditions and practices for such things as AFB control and the (then quite indiscriminate) use of agricultural chemicals.
  13. This dates back to 1984, and was mostly relating to the Bay of Plenty and Waikato areas...
