Canvas tents have been around since before they started making tents out of nylon, polyester and other synthetic materials. I own two canvas tents myself, both a Kodiak and a Springbar.
From Wikipedia, the free encyclopedia. The conditional perfect is a grammatical construction that combines the conditional mood with perfect aspect. A typical example is the English would have written. The conditional perfect is used to refer to a hypothetical, usually counterfactual, event or circumstance placed in the past, contingent on some other circumstance (again normally counterfactual, and also usually placed in the past).
A speaker uses the conditional tense when s/he refers to a situation time that is posterior to an orientation time which lies in the past time sphere. The use of the conditional tense does not specify whether the situation time is anterior, simultaneous or posterior to t 0.he English future perfect is a complex tense which can also be expressed in one of two ways. It is either composed by the verb will in the present tense + the perfect infinitive of a main verb (25); or by a form of be going to in the present tense + the perfect infinitive of the main verb (26).
