In the first place, the C a C/3 and C u/4, as we understand, are not critical; and supplies of these fibres are araple for the United Kingdom and the United States. However, last fall we arranged to have 10 tone each of VRA/3 and VRA/4 sent to the United States for exporiraental parposes. Thsse fibres were evaluated by Johns-Manvilie corporation, which la the cnief user of these gradeB, outside of Kessbey & lattiaon. They found that the fibres wars tulcy and not squivalsr.t to the C u u gradSB end thsy would not uss then .nder any cireuautar.ces. Mr. Uuenlsck, President of Keasbey A Mattieon, stated that they ouM nave no use for the YRa/3 ami VRA/4 graaes. In the case of HVL/3 end HVL/3XI, Jolms-Uunvllle had provi"-* experience with these fibres end found that they are not suitable for Lneir use. Mr. Uuehleelr agreed that he coulo take 50 percent HVL/3 in place of C a G/t; however, he has no use whatsoever for the HVL/3XX. ' In the oase of the VRA/2 and HVL/k, it would be important at ti.ee to investigate their suitability for Cato, if it sere not "1 -**dy i-T*. 1-'* - for a aaspie of VRA/k. This fibre was very carefully examined by Raybeetoe-Mannatton, Inc., wnicn is tne principal user of the C it G/2 grade. They nade very careful tests of VRA./.. against C & C/i, ar.d It was found that tr..? shrinkage as received, after crushing and after opening, was considerably in excess :f C Sr d/2.
