Since the last report, dated June-30, 1890, there havé been made itn+! provements in the Cabinet of a most thorough and satisfactory character. We have removed entirely the heavy and cumbrous walnut shelving running through the glass cases from end to end, and which proved obstructive of light, and therefore detrimental to the exhibition of speci- mens, and substituted therefor large plates of glass supported horizon- tally on light, turned pillars of walnut. In this way we have not only obtained more space for the arrangement and exhibition of the specimens, but also have secured an improvement in their illumination. In addi- tion to this improvement, we have substituted for the heavy-railed, double glass doors forming the walls of the glass cases, lightly framed doors containing each one large glass plate, with the effect of an increase in the light of over 30 per cent—a matter of great moment in the exhibi- tion and view of minerals. At the present time, therefore, the Mineral Cabinet presents a much more attractive appearance than formerly, and permits a more thorough examination of its contents. During the past two years the Cabinet has been visited by several thousand visitors, both citizens and strangers, and it forms apparently a very attractive feature of the Capital City. Moreover, showing as it does, in a way not to be misunderstood, the varied character and great extent of the mineral resources of the State, it cannot fail to be advan- tageous in the way of attracting citizens and capital to California. During the past two years we have added some specimens to the col- lection; some of these have been obtained by the individual exertions of the Trustees, while others are duplicates presented by the State Min- ing Bureau. These additions, and also those made during the previous biennial period, together with perhaps a thousand specimens found in drawers and not hitherto catalogued, will render necessary a revised catalogue. This the Trustees have authorized the Secretary, Dr. Pyburn, to prepare, and if the consent of the honorable Board of Examiners can be obtained, to have it printed in such numbers as may be deemed neces- sary for the use of visitors. It is proposed to make this new catalogue not merely a list of exhibits, but in addition a popular treatise on the properties, uses, modes of procuring and reducing such classes of min- crals as are most abundant and interesting to the citizens of California. Thus, the Cabinet, in connection with the catalogue, will form an edu- cational as well as a spectacular exhibition. Following is a statement of expenditures made during the period intervening between the previous report and the present one: ‘Geo. H. Jost, for wore on Cabinet and for materiale. soo ee fio
