Thе only issue before us in this tax case is whether the petitioner mined quartzite, which would entitle it to a 15 per cent depletion deduction, or sand, which would call for a 5 per cent deductiоn. Section 114(b) (4) (A) Internal Revenue Code of 1939, as amended by Section 319 Rev.Act 1951, 26 U.S.C.1952 ed. Section 114. The taxable years are 1951, 1952 and 1953.
During the period involved petitioner mined or dredged sand from deрosits near Dividing Creek, New Jersey. The process consisted of removal of the top soil, etc., until the sand was exposed. Dredging removed the sand through pipe lines to screening statiоns. After screening and washing it was transported to concrete storage silos where it was stored and dried. The sand was then sold to a distributor who further processed it and sold it to glass manufacturers principally. The primary chemical content of the sand, 98.98 per cent, was silicon dioxide. This, plus its low iron element, 0.151 per cent, made it useful for glass manufacture. The sand has the crystаllographic structure of quartz and is angular in appearance. It is the result of disintegration of a type of rock formed, through the cementation, by a silica cement, of sand grains.
Petitioner’s main argument is that its expert characterized the sand as quartzite and since that was the only evidence on what it calls a question of fact, it should prevail.
It is true that the witness, in his opinion, classified the cobbles, pebbles, granules and sand which he found in deposits of the petitioner sand company as quartzite. However, immediately thereafter, still on direct examinаtion asked to “ * * * give us the defintion or general meaning of the term, ‘quartzite,’ he answered:
“I would say that the definition which is generally accepted by geologists is that quartzite is a rock composed essentially of quartz, which is formed from a sedimentary sandstone by the introduction of a silica cement. This silica cement is often in crystallographic continuity with the original quartz in the sedimentary rock.”
*593 Still later he stated that the sand was included in the common commercial meaning of quartzite and “This sand also adheres to the technical — the technological definition of quartzite.” He agreed that the correct diameter of sand is from .06 to 4 millimeters. He said that sand had no meaning apart from the size of the particles and that “Sand is a grain size of material derived from rock. That is, it is an inorganic, naturally occurring material, a rock which is produced into the size of sand.” As to the petitioner’s sand, he said, “ * * * it still retains the characteristics of quаrtzite, that is, the aggregation of quartz grains.” Counsel, stating petitioner’s position, told the Tax Court, “I have always contended that this is quartz sand which is quartzite, and I now so contend.”
The depletion allowance is a matter of grace. 1 The allowances we are here dealing with are 15 per cent for quartzite and 5 per cent for sand. The product South Jersey Sand Company mined and marketed was admittedly sand. While the expert’s definition, above quoted, of quartzite would not seem to include sand, nevertheless he says it does, and that the sand would also be included in the commercial meaning of quartzite.
, Had the Tax Court’s decision turned on the acceptance of the expert’s opinion, having in mind that it was the taxpayer’s burden to establish the rightness of its contention, 2 from our own review of that evidence there is ample justification for the Court concluding that “ * * * his testimony is not satisfying that petitioner’s product is commonly or commercially referred to as quartzite. * * * We were far from convinced by his testimоny that such sand is in fact commonly or commercially known and referred to as ‘quartzite’.”
But the Tax Court’s decision cuts far deeper than that. As it stated: “The Court is not compelled to rely on petitioner’s witness in discovering the sense in which Congress used certain words.” That, we think, is the nub of this case. We are here dealing with and guided by what Congress meant by its unmistakable affirmative distinction between quаrtzite as such and sand. We are seeking the commonly understood definitions of the terms. 3 Aside from the statement of the expert, the record is bare of any indication that commercially thе rock quartzite is merely industrial sand because of similar chemical content. The circumstance that quartzite may be reduced to sand prior to being used in the glass industry does not reflect Cоngressional acceptance of the two products as identical. The statute allows the fifteen per cent depletion for quartzite not for glass manufacturing substances.
The legislative history reveals an understanding and awareness of the classification of sand and gravel by themselves as basic materials; that pure silica sand (as before us) is the principal сonstituent of glass. (Testimony of the chairman of the National Sand and Gravel Association, 1 House Hearings, Revenue Revision of 1950, p. 311). The next year, 1951, the chairman, again as a witness, *594 sought specifically to raise the depletion allowance for sand and gravel and industrial sand from 5 per cent to 15 per cent. (House Hearings, Revenue Revision 1951, Part 3, pp. 1539-1545). See also Senate Hearings, Revenue Act 1951, Part 2, p. 885. It is a fair evaluation of those hearings with respect to sand and gravel, particularly industrial sand, that they were considered as completely sеparate materials with not the slightest indication that they were to be classed or confused with quartzite. Actually at the 1953 House Hearings, General Revenue Revision, Part 3, p. 2071, a represеntative of the quartzite industry testified that quartzite is “ * * * a firm compact rock composed of grains of quartz so firmly united that fracture takes place across the grains instead of around thеm.” The entire legislative history shows, silicon sand and generally sand and gravel to have been accepted in the one group, small separate grains; and quartzite by itself, a compact granular rock, which as such during the critical years was awarded a higher depletion allowance than loose sand and gravel. And we find nothing in the later Section 613 of the Revenue Cоde of 1954, 26 U.S.C.A. § 613, or its history that lends comfort to petitioner’s view that its industrial sand is quartzite.
All ordinary definitions of quartzite and sand stress the visible, readily discernible dissimilarities between the two. Quartzite, the hard compact rock. Sand, hard small grains. There is no attempt to merge the one into the other. See Webster’s International Dictionary (2nd Ed. 1950); Encyclopedia Brittanica, 1952 Ed.; a Glossary of the Mining and Minеral Industry, Bull. No. 95, 1947, Bureau of Mines, Dept. Interior We have neither seen nor has our attention been called to any common or industry usage which attempts to eliminate this very real visual distinction between quartzite and industrial sand. 4 The Commissioner and the Tax Court were bound by the 1939 depletion statute. Any relief from that for industrial sand was a matter for the Congress.
The decision of the Tax Court will be affirmed.
Notes
. In W. R. Bonsai Company v. United States, D.C.W.D.N.C.,
Without having the full record of the case we cannot of course discuss it in its entirety. However, it is apparent that the industrial sand presently before us is not within the 1856 report definition of quartzite approved in Bonsai. It is also clear that the second North Carolina report, dealing with the very product before the court, made a sharp cleavage between even grаvel consisting of quartz and quartzite pebbles and sand and clay, though in the next sentence it would seem to classify pebbles as sand, contrary to both geological and commercial сlassifications. The Bonsai facts may well be distinguishable from the case at bar. If they are not, in our view, the decision fails in its construction of the 1939 depletion statute.
