The esti-mates range all the way from $ to $ for thematerial required for these 50 columns. We admitthat the estimator furnishing the low figure does notspecify the amount of material necessary for the job,and so we cannot determine if he has made any errorin taking off his quantities. That is a possibility, ofcourse, for previous studies have shown that millmen,as a whole, need some instruction in quantity other estimates show practically the same amountof material in each case, the proportion of waste, how- Our November Subject -— fx DP j* Z-6- 1 -> -3-9- x 3-2 v Readers are requested to submit their ideas of the cost of this pairof garage doors for the November issue.

The firm whose estimate washigh, $, put the price of the material at 50%above anybody else, which accounts for the unusuallyhigh figure. On the question of labor the figures tell an inter-esting story. With bench hours running from 25 to125 and machine hours from 12 to 100 there is surelysomething in error, especially when the firm that es-timates a small amount of bench labor also estimatesa small amount of machine labor. Quite frequentlyit is possible that one firms estimate will show anunusually high amount of bench labor, but it shouldshow a corresponding decrease in machine labor orvice versa. The rates charged for labor are fairlyuniform, bench labor rates at from $.6
