732 The Architectural Review and American Builders' Journal. [May, INSTRUCTION FOR STUDENTS. WE have in preparation a course of gradual instruction for young men who are desirous of improving their time by the study of geometrical drawing, which will shortly be com- menced in the Review, and be continued each month, occupying from two to four pages. In these lessons we will en- deavor to brin 2: the Art of Drawin° with its accompaniments of shading and coloring, within the comprehension of all ; and we trust that the consequence may be a great increase of students of Design throughout the country, not alone in our large cities, where there are means and opportunities, but in places remote from any such, where the young taste, ardent for development, may want the very assistance we now propose to give. Nor is it the architectural student alone, or the builder's apprentice, that these lessons are intended for ; but for the use also of those who desire to cul- tivate an acquaintance with Archi- tecture — an art so necessary to the civilized world, and one whose works are everywhere to be met with. The vast increase of facilities of travel are making its monuments in every land more known ; and therefore the too neglected study of its beauties is now grown to be a necessary requisite of a complete education, and calls for every aid to its development. The Architectural Review will do its share in the advancement of the cause, in the hope that its efforts may be productive of a growing desire for that knowledge which every mind imbued with feeling and taste should possess. FIREPLACE HEATER. THIS is a new arrangement of the Bal- timore fireplace stove which claims the superiority over its rivals, and conse- quently assumes the title of Champion. It is a very handsome design, and has many excellent improvements. But, in such matters trial is the test, and all who have had experience of the old Baltimore Fireplace Heater and ap- proved of it, will no doubt, extend a welcome to this new aspirant, whose warmth of character ought surely com- mend it to a corresponding reception by all who believe in the power of im- provement. To our readers who are ignorant of the properties of this sty& of heater we would say that the heat from the room below, in which is the fire, is conveyed by a flue to the fire- place chamber in the room over it, and thus the one fire is made to do the duty of two fires and the apparatus which transmits the greatest amount of heat with the least annoyance from dust, is unquestionably the best. This Cham- pion Fireplace Heater claims to have these advantages in full, and moreover presents a very bright appearance from the very full view of the fire, which is had through the mica lights occupying nearly the whole front, being a large segment of a circle. Monument to Humboldt. — Many of the leading citizens of New York pro- pose to commemorate the hundredth birthday of the great author of the Cosmos, by the erection of a monument to him in Central Park, to cost $2,500. This is a compliment alike worthy of the man and the city.
