On removirip the White Scale.

houses have been much admu'ed. We have also a testimonial 

 of Mr. Reynard, who declares that he considers the houses 

 which Mr. Crosskill erected for him " to be in every respect 

 most complete, both as regards the workmanship and the de- 

 sign." He adds, addressing Mr. Crosskill, " They reflect much 

 credit upon yourself and workman, there never having been one 

 screw out of order, or one broken pane of glass, since they were 

 put up. — E. H. R. Sundeiiand-'wick, May 8. 1836." 



[To us, the most remarkable feature in Mr. Crosskill's iron hot- 

 houses is their cheapness, as compared with the price of iron 

 hot-houses either in London or Birmingham. Whether the 

 workmanship is equally good, or not, can only be ascertained by 

 a minute comparison ; which we, of course, have no opportunity 

 of making. We have done our duty, in having brought Mr. 

 Crosskill's claims as a hot-house builder fairly and impartially, 

 as we think, before the public]
