Such a pump is shown in Figure 14 and costs from $30 to $50. For orchards of over 500 trees a power outfit will be found more economical. Gasoline engines are now most generally used for power, and are desirable in that many types may be detached from the pump and used for other purposes during the winter. Such outfits with engine, pump, tank, and tower, all mounted on a suitable truck, are sold by all the loading pump makers at from $250 to $350. Several are now in use in New Hamp- shire and giving excellent satisfaction. Frequently one can be used by several parties or for a whole neighborhood. One vounu' man purchased one this year, and in a com- munity where practienlly no spraying had been done before, secured enough work to pay for the outfit. In our own work we have used a carbonic-acid gas spra^-er very satis- factorily. The outfit is shown in Figure 16. The li<inid carhonie-aeid gas is allowed to pass into the steel tank containing the liquid and forces it out, without the use of a pump. The operation of the outfit is simple. The expense of operation is somewhat greater than for gasoline power, but the investment is not as large and tlie weight on the truck is much reduced, so that a heavy will |)iill a 100 gal- lon tank on level ground. The gas sprayer cannot, however, be used satisfactorily with lime-sulfur mixture. ^lost New Hampshire fruit growers will find the barrel pump best adapted to their needs, for by the use of a row attachment it.
