Excerpt from The Tarnished Plant-Bug and Its Injury to Nursery Stock Gain in height at withers.-the changes in the measurements are shown graphically so that the data may be studied better. The comparative growth of animals is better shown by changes in the measurements rather than by the actual measurements themselves. Figure 9 shows the gain in height at withers of the animals upon maintenance. The rate of gain varies somewhat, but it is about the same for the three youngest animals, Steers 164, 197, and 589. These were about one and one-half years old at the beginning of the trial. Steers 18 and 588 were about two and one-half years old and Steer 48 was about three and one-half years old. This last steer, how ever, was on full feed during all the time represented by the measure ments given in Table 11. It is seen in Figure 9 that the three young steers on maintenance gained in height as rapidly as the full fed, old steer. Since they were younger it is very probable that their impulse for grt was greater than that of Steer 48. The better plane of living of the latter seems to have been sufficient compensation for this handicap. Steer 588 was a year older than the young steers, and so had already obtained more of its growth. The rate of gain was slower and it took 34 months for him to make the same gain made by the young steers in 17 to 18 months.
