The sine in fuse produced is computed daily usiny thw latest available and assays of slag received and treated, the computed weights of slaj produced (ty iir.c and load assay formula) I and no lose of either metal. This assumes the balance of treatment less aiaj produceu to be 10o/ volatilized F Into fume. All lead treated is recovered in fume end IOC# of the sine treated less tr.at coc.puted to La in tnu l slag produced is recovered in fume. A loss in either luetal is recognized uniy when the computed -invert lory looks F unreasonable from paet clean-up a^eriance. The last clean-up of tlm fluey and bpt-, house was made in October $1951 and Hr.Thompsonstated that the fume weighed out proved the book fig ora to reasonable. . AtFebruary 29, 1952, there were 50 tons of low-grade fume reported oulaJda the flua and two cars (about 5,80 tons) of high grade fume. The balance of the computed Inventory was classes as hijh-rrode fume in the flus [and in the baghouss. [ * Fume In-Transit Fume in-transit is derived from cars shipped from Easo Helena but not receive! ct their destinaticn. [Tbs February 29, 1952 inventory consisted offers enroute to Great Fulls, hard) 1952 weights and assays uere ; M#d to compute weights end contents. All cars shipped in February were ecucunied for in the audit. I MBi'fORr VALUATION ` As reported before, valuation of inventories is confuted on tha lust-in first-out basis on zinc Eeontent of the fume. The base for this system was liecatiber 31, 1943, and has beenbuilt up as follows to member 31, 1951* Deoember 1943 June 1943 December 194?
