buildings, and collecting in a permanent exhibition all materials, appliances, or inventions of a practical or ornamental character. Its advantages are: First, educational, by placing before the interested public an aggregation of building intelligence in the form of exhibits of the actual materials, appliances, and inventions employed in modern construction. Second, that in the fact of such centralization of materials, a vast amount of time is saved to the public concerned in building interests. For those who desire to build, information is not only gained regarding a large variety of improvements, but obtained in a minimum quantity of time.

The Institute of Building Arts is free to the visiting public, who are welcome to all its advantages of information and to the inspection of the numerous exhibits it contains. It furnishes gratuitously, to any one who may inquire, information relating to building improvements. It maintains a series of tests of materials, the results of which may be obtained by anyone asking for them. Courses of lectures given by skilful specialists instructive in the many sciences and arts of Architecture are given under its auspices.

The management of the Institute is strictly impartial as to the merits of the exhibits, having no financial interest in any sale. The purchaser has perfect liberty to examine the exhibits and negotiate with any exhibitor. It is the duty of the management to protect each and every display from any impositions or trespasses on their several rights, and to explain to any inquirer the qualities and merits of the material or invention, as claimed by the exhibitor, but to give no individual expression of views for or against any exhibit. The examiners are to be left perfectly free to judge and accept from their own standpoint.

The important work of the Institution has made of it a central point of great interest to all connected with or interested in architecture and its kindred arts, and those who are identified with the work will not fail to be amply repaid for their interest or their labor in its upbuilding.

It became necessary a year ago to increase the floor space, and nearly one half as much more space was secured and the rooms are crowded with beautiful and instructive exhibits. The Illinois Chapter, A. I. A., has fitted up a fine library and meeting-room in the Institute, which it throws open to the interested public, who find the many pictures and books therein a great enjoyment and benefit.

The other exhibits above referred to are strictly commercial in character, and conducted in the interests of the exhibitors, and consequently may not command the prestige possessed by the Chicago Institute. Nevertheless they are important educational factors in their special localities and are a great convenience to all connected with the building trades. Every large commercial centre should be thus supplied. The success of those already established will doubtless lead to the early establishment of others. Architects and manufacturers both need only to observe the workings of any of the exhibits which we have mentioned to be convinced of their great practical value, and each individual will be enhancing his own interest while contributing to the success of all the others concerned by lending whatever assistance he can to this most praiseworthy enterprise.

Notes.

An architect cannot work to the best advantage without the best and most convenient appliances. It is true that sometimes the cleverest and most skilful draughtsmen appear least concerned about their instruments and materials, and often produce work showing wonderful dexterity and mastery of technique with the most imperfect working materials. But this is exceptional. After years of study and practice one may be able to produce with the sharpened end of a match, or with a toothpick, drawings which it would tax the skill of an ordinary draughtsman to approach
