Abstract: A necessary condition for factoring continuous linear maps with domain $ {c_0}$ or $ {l_\infty }$ through a class of spaces which include the $ {l_p }$ spaces (in fact, include the $ {\mathcal{L}_p}$ spaces) for $ 2 \leqq p < \infty $ and a weaker result for $ {l_1}$ are obtained. As an application, examples of Schwartz spaces are constructed and used to answer questions of Diestel, Morris and Saxon; in particular it is shown that there are Schwartz spaces which cannot be embedded in a product of $ {l_p}$ spaces, $ 1 < p < \infty $.
