Products supplied to agriculturists over the years included instruments such as "Sayers" brand
drench guns, castrating and tailing instruments, cattle syringes and needles. Chemicals marketed in the 1940s and 1950s included drench compounds "Blue-Nik" (
copper sulphate and
nicotine, indicated for large stomach worms, hair worms and black scour worms), "Green Seal" (
carbon tetrachloride, for use against worms and liver fluke), and "Phenmix" (
phenothiazine, for stomach and intestinal worms). Other products marketed were "Barconite" for treating "fly-blow" in sheep. Few of these materials would today be available or recommended for the use prescribed. ;S.A.P. In 1902 the company began marketing this poison, which was, where laid, spectacularly successful against the
rabbit pest. In 1906 the company purchased the recipe and manufacturing rights for "Rabbo", a similar product, from G. McGirr of
Parkes, New South Wales. An active ingredient of "S.A.P." was
phosphorus, and was quickly suspected of starting grass fires, such that competing products such as "Vernox" were soon being marketed as being safer in this respect, though "Vernox" and others such as "Deathtrail" and "Grim" all contained free phosphorus, in perhaps different concentrations. The advantage of phosphorus as a poison is that, in dry weather and if not strewn as clumps, it degrades to innocuous
phosphoric acid within a week and is harmless to stock. ;Thall-Rat The active compound in this rat poison was
thallium sulfate, imported from Germany. Its advantages as a rodenticide, that it was odorless and practically tasteless and swift acting, were also realised by amateur poisoners; it was also inexpensive, required no licence to purchase, gave symptoms similar to known diseases, and one gram was sufficient to despatch a human. Its one disadvantage in this application was that it did not degrade, and could easily be detected many years
post mortem. After a
spate of such poisonings in Sydney in the early 1950s, given due prominence in the Australian press, and the exhumation of more suspected victims, its ready sale was prohibited. ==The founders==
