There isan infinite variety of this general type ofboiler. They have tubes of all shapesand sizes, placed at all angles. Thesetubes are connected with many types ofsteam and water drums, placed somewithin and some without the boiler boilers are supplied with feedheaters, air heaters, and all sorts ofeconomizers. But the boiler that we want,the boiler that we must have, has certainfixed requirements of design. Many ofthe types of water-tube boilers fail atonce to satisfy those requirements. Isthere one that will satisfy them all? Ifthere is such a boiler, which one is it?If no such boiler vet exists, what modifica- Fig^.

As the time required to raise steamfrom a cold boiler is largely due to thetime required to heat to the boiling pointthe water contained in the boiler, in orderto have boilers that will be capable ofraising steam quickly, we must havel)oilers having a small amount of con-tained water as compared with the cylin- • drical boilers that arc now in use. There are many other lessons to bedrawn from the late war between theUnited States and Spain, but the necessityfor the use of water-tube boilers is thegreat lesson to the engineer. To knowthat certain qualities of this type of boilermust be obtained to insure satisfaction,is also interesting. To have a successfuland satisfactory water-tube boiler wemust have a
