As is well kno%vn, the Baldwin Looomotive works are locafed iu the boart of the city of Philadelpbia, where real estáte is valuable. This condition of things leads to a great ïiiany details iu the construction of the works which would uot be thought of uuder different oircnmstances, although, as very often happens after eme has aceoinmodated himself to circurnstances in this way, the result is found to have uo disadvautages, but, ou the contrary, is íouud to be positively advantageous. One of the features of the Baldwin works, which is a blaoksmith shop, steam hamuiers and all, is located on the seoond floor. ïhis shop does wliat the Baldwin works cali the ligbt work. It does not do the frame forging or other heavy work, although the work done is, as already intimated, sufficiently heavy to cali for steam hammers. The entire shop containa 8" forges, served by two fans, which are driven by electric motors. A complete system of oxhaust piping for barrying away the smoko is provided, which, to gether with the very liberal wiadow and skylight area and elevated looation results in the cleanest and lightes shop wheu the mimber of íires is con sidered, tÜatwe have ever seen.- Amer ican Machinist.
