Only the salts, never the esters, of 2,4-D can be used for this work. A 20 per- cent solution appears the best con- centration and is often manufac- tured and sold at this strength. Perhaps the best method for ap- plying is that of constructing a light wooden oblong frame, cov- ering this with any handy absorb- ent fabric and nailing a stick at each end of the frame for carry- ing by two men.

Smaller ones could be made for singleman treatments. The fabric is then wet with the concentrated 2,4-Dâas wet as pos- sible without allowing any drip. The wetting of the fabric should be done on the shore of the bog ^ away from cranberry vines which are readily injured by contact with 2,4-D. Then the wet rack is car- ried across the bog wiping the shoots of 3-square grass, care being taken to keep the poisoned fabric above the reach of cran- berry vines. The operation niay have to be repeated, but since the chemical is both inexpensive and easy to apply this does not appear a serious handicap. This method and material when applied to other tall-growing weeds may be found to control weeds other than 3- square grass. Stoddard Just a word about Stoddard Sol- vent which does not appear on the 1950 Weed Chart. Generally speaking, Stoddard burns down weeds with great rapidity and, provided it is applied before cran- berry vines have started their sea- son's growth, does this selectively. However, in the great majority of cases where it was sprayed in 1949- weed roots were not killed, and new tops were conspicuously evident 4 to 6 weeks after treatment. It appears that kerosene sprays, taking longer to kill the weeds on which it i<^ applied, do a more thorough job of destroying under- ground stems and roots, and grow- ers in Massachusetts are well ad- vised to continue with kerosene until mo
